- This video is about how to build an Aircrete foam generator for a reasonable price. I was able to build this for about $85 because I got the diaphragm pump on Ebay used and had the air regulator sitting in my garage from another project. Let me know in the comments section if you have any questions.
I got the foam concentrate from richway.com/construction-prod... You will have to call them to order it and it is $50 for a gallon.
Here is a link to the Foam Generator schematic drawing that was in the video. drive.google.com/file/d/1rMhH...
Here is a link to my video on how to make the foam wand that goes with this generator. • Aircrete Foam Wand DI...
And here is a link to my How to make Aircrete the right way. • How to Make AIRCRETE T...
And also a link to my homemade cement mixer that I designed specifically for making aircrete. • Homemade DIY 55 Gallon...
Here is a parts list of the items you will need to make this generator. I didn’t use either of these pumps so you may need some clamps or fittings that I didn’t use to make either of these pumps work. I found my pump used on eBay and usually there are used pumps for sale in the $40-$60 range. Hope this helps.

Hi DH! Thank you so much for your kind comments! You made my whole day! Please let me know if you need any information or help if you build a foam generator. Peace and love to you!🙏😊❤️
Dear @@PranaTech thank you, I will certainly not hesitate to ask you about anything I need because you are a school and I learn from it 🙏🙆❤️
You're the first aircrete builder I've found who is willing to share info instead of selling info. Liked, subbed, bell rang, and I'll be sharing with my family.
Hi Karston! Thanks for the great comment! My goal is to show people how to un-enslave themselves and build their own home for a reasonable price. Not hundreds of thousands of dollars. Glad you found my channel! 😁🙏❤️Don
This video is a real wealth of information on building one of these, thank you very much for taking the time. Really liking all of your uploads.
Thank you Stewart for your kind words! I appreciate it! 🙏😁
Fantastic video! Explained very efficiently. Best video on the topic I have seen so far. Thank you so much for making and sharing!!!
Hi Morgan! Thank you so much for your very kind comment! I really appreciate it!😀🙏❣️
Great info mate, thanks for taking the time to make it and share your hard earned knowledge.
Thank you for the great comment, I appreciate it!😀👍
Thank you very much for explaining how this works. Some CZcams channels are charging for the information. Good on you for posting this up - Thanks!
Hi Phillip, thank you for the great comment and for subscribing! Wow, I had no idea people were charging for this stuff! My hope is that anyone can build one of these at home and I eventually am going to build my own dome home out of this stuff. I am building an affordable concrete pump that can be built at home and will be used for Aircrete and shotcrete. I’ll post up the how to video for that as well when I’m done. Have fun out there! 👍😀
@@PranaTech It's definitely a cool way of making concrete things without the associated weight. You got my brain gears going for sure - ;o) Good luck with your future projects. I'm looking forward to seeing what you come up with...
i have watched dozens and dozens of foam generators but i believe yours is the best. simple and yet very effective. thank you
I have no idea how I missed your nice comment. Thank you so much!😊🙏❤️
Very well done, You are truly a valuable source of great information. Thank you
Hi Glenn, thank you for your nice comment! I really appreciate it! 👍😀
Excellent design which offers full control over the physical properties of aircrete. Thanks for your unique and valuable set of instructions. You are changing the world 😉.
Thank you so much for your very kind comment! I really appreciate it!😊🙏
This is definitely the sleekest DIY foam generator I have seen on CZcams.
Thanks Dennis!😊🙏
You are a good man. Thank you. I wish you success
Thank you my friend! I appreciate your kind comments very much! 🙏😊❤️
Thanks for the demo and name of foaming agent -and- I just realized that the foam you just made can be reused once the air in the bubbles break - soooooo - it would always be a good idea to capture all extra foam in a clean, covered container! I hate waste and soaps are used as pesticides - so, not good to soak the ground! I've been watching many aircrete videos and am trying to learn as much as possible before tackling my first projects!
Seen so many videos, this is definitely very detailed and to the last part. Thank you and look forward to learn more. 👍👌👌
Jyothirmaya, thank you for your nice comment! Stay tuned because I am about to release a new video with an even simpler foam generator with parts that are available worldwide and uses only air pressure to operate. Thank you!😀🙏❤️
@@PranaTech Yes sir! Please do it... Out of many videos that i have watched, yours are definitely among the best. Love your detail, rigurosity and accuracy. Inspiring!
Thank you so much Alejandro! I am just finishing up with testing of the new design and it is working great! I’ve designed a new foam wand as well because my old design could not handle the higher output of this new generator. I should have the new video edited and uploaded in the next 4 to 5 days. Thanks for your comments!😁🙏
I really appreciate your time producing this video, thanks for sharing, one of the best on YT, and the foam results are excellent!
Thank you my friend! 🙏😊
Question, it is possible to increase the flow of the foam? how? a bigger pump with a 2" pipe? TIA! @@PranaTech
Yes, here is a link to my bigger pump build. czcams.com/video/L-SAHq9X9QQ/video.html and here is the larger output wand video czcams.com/video/UU5USOZL7cQ/video.html 😊👍
@@PranaTech thanks a lot!
You are very welcome! 😁
Congrats'!! That is a very simple and effective CAF generator.
Hi Simon! Thank you very much for your kind comments! I really appreciate it! 🙏😀
nicely done. Thanks
Great design & follow up. I thank you my freind.
Thanks Jim!👍😊
You are Very brilliant , thank you for valuable information. God bless you and family
Thank you Rafael for your very kind comments! Bless you as well my friend! 🙏😊❤️
Just com across with this video. Love it. Thanks for a sharing lesson.
Thank you for the nice comment! 🙏😊
yeah, thanks for putting this out to the masses.
You are welcome!👍😊
Thank you so much for this great video and for sharing your schematic on how to build the pump set up. I hope you have at least created an Amazon affiliate account for all the links you provided. nothing wrong with making a few $$ for providing all this great info for free.
I am a new subscriber and have already started building from your designs, especially the Milwaukee portable band saw stand, pure genius!! Thanks again.
Good morning Tony! Thank you so much for your nice comment! I had forgotten about Amazon’s affiliate program. Thank you for reminding me! I am going to sign up right now. Let me know if you have any questions about anything you are building and I will get right back to you. Thanks, 👍😀Don
Gary Yourofsky.......
THANK YOU ♥️
YOU ARE A GENIUS.
Hi Ronald, thank you for your kind words! Keep watching as I am finishing up an even simpler design for a foam generator that will be even easier to build and use. 👍😀Don
THANK YOU,, VERY ESPECIFIC THE ANSWERS, FOR A LOT OF PEOPLE. HAPPY FATHERS DAY
Thank you Jesus! I appreciate your kind words! Glad you liked my video!🙏😊
Thanks for the video and the schematic. I used your for the basis of my design with a couple of tweaks. I did not ability to weld up a box, so I just bought a 20" toolbox with metal latches. I also put a "equipment switch" that has the three prong mail adapter. That allows me to remove the cord and store in one of the lid storage areas. I put my suction tube in the other lid storage. The interior tray fits the 13" wand and hose. All in one need box you can carry and store easily.
Hi John, I like the way you think! Using an existing tool box saves a bunch of time an I like the removable cord and storage idea. Thanks!👍😁
@@PranaTech Thanks, did not realize how bad the spelling and grammar was on my post. We are going to make aircrete ICF (much like e-z block for our house build. I would be interested in your pump you mention in the thread if you have moved forward with it.
High John, great to hear from you! Sounds like a great project you have for your home build. You’ll have to do some experiments to see how high you can can stack your block before you do your grout fills on the cells. Aircrete doesn’t have a lot of tensile strength so the side loading that the grout filling will have may necessitate the addition of some fibers into the Aircrete to add some cross sectional strength to your blocks. My large pump is a little delayed right now as I’m in the process of clearing a part of my property to build a bigger shop. The design is exactly the same as my high output foam generator but I used a 1” diaphragm pump for the higher volume of foam production. 😁👍
@prana-tech, thanks so much for your awesome videos🙏 when you say that CLC doesn't have tensile strength, you can solve that by using rebar right? Or adding some fiber to the mix?
Hi Ian, adding some fibers would increase the tensile strength for sure! Rebar would not help because the problem is that there is so much air in the final product that it becomes very brittle and breaks easily.👍
Very impressive nice simple build.
I too am very impressed!
Not just the degree of technical knowledge and easy to understand guide steps but you stand alone in not trying to sell me for workshop, video tutorials, pdf files, gadgets and what not... Not that I would not buy from you if I really needed to have it, but its refreshing and so I SUBSCRIBED!
I have my desert land and after the "conjob-19" ceases, I plan to build right away! -- hope I can ask questions from time to time?
Hi Peter, thank you for your kind words! My goal is to show others how to build stuff themselves for a fraction of the cost. Please feel free to asks all the questions you want. I’ll be glad to help! 👍 By the way, I’m a firefighter as my day job and this is most certainly the biggest con I’ve ever seen! 🤣
Thank you!
Excelent Great design Thanks for taking the time to make it and share your knowledge fron Venezuela
Hi Elis! Thank you for the nice comment! I just came out with a new design that is even easier to build and has a higher output. Here’s a link to it. m.czcams.com/video/L-SAHq9X9QQ/video.html
Enjoy! 😀👍Don
@@PranaTech Thank you very much, I am precisely watching your channel at this moment. Thanks for the link God bless you
Awesome! God Bless you as well my friend! 🙏❤️
Great videos! Thanks for sharing your awesome knowledge! Starting mine tmrw ;)
That’s great! Let me know if you have any questions when you get building. 😁👍Don
Hi Don, I have been looking around different stores around my place, and the closest pump to the one in your system has has the following specs:
Centrifugal pump, 18L/min, Total head 10M.
The biggest model is giving 25L/min and has a total head of 18M.
If I am not mistaken they are far from the 90PSI needed. What do you think?
Hi there, the important thing with the pump is that it puts out at least 60 PSI to balance with the air pressure. Otherwise the air is trying to push the water back into the pump. 👍😁
@@PranaTech Good morning, hope you are well. I wanted to ask you: with your experience, do you think that the size of the tubes I pick will matter much in my final mix of foam?
My pump should deliver 160 PSI with a debit of 5.5 LPM and I am about to use 1/2 inch tube to connect with the Y fitting.
My Air system has tubes of 1/4 inch, and might be of a lower pressure (usually standard Air compressors deliver around 120 PSI).
Do you think that my tubes, on both air and water side need to be same diameter and equal pressures? Or it doesnt matter much?
For the water pressure, I have been thinking to add a regulator to reduce it. Any advice?
Thank you very much for your help,
Nico
Good morning Nico! All is well here and I wish the same for you! As far as the lines go, I think you will be fine with the ¼” air line. The diaphragm pumps seem to adjust their pressure to match the air pressure where they meet in the y fitting so I believe you will be fine. Your pump’s output is quite a bit higher than mine so you may need to just put a ball valve inline to reduce the outflow. I would only do this if the foam was coming out to wet and I was not able to balance it by increasing air pressure. My gut feeling is that you will merely have to run a little higher air pressure than I do to match the output of your larger pump output. Most of the time I run right at 60psi of air pressure to make great foam. To make sure your foam is good, once it is thick and creamy like shaving cream, fill a 5 gallon bucket (19 liters) and it should weigh 3 to 3.5 pounds (1.36 to 1.58 kg). Hope this helps! 👍😀Don
Thanks for sharing!!
Hi Jose! You are very welcome! Thank you for your kind words!😊👍
Thanks for the info I have noticed the price some guys are charging for these and it's ridiculous. First tme I have seen the pump pressure and air pressures given which was bugging me. Cant wait to see how you do with your next project, thankyou from John in Tasmania
Hi John! Glad you liked the video! I built a larger model that is all air powered and the video is in my Aircrete section of my channel. m.czcams.com/play/PLU9BfNsb74M8mbnLDf3ILVchM0WyVZATS.html I’m also currently building an even larger “Big Kahuna” model that I should have finished up and out on video soon. 👍😀Cheers!
Very nice!
Thanks Hank! 😊👍
Thanks for sharing!
You are very welcome Bobby! Thanks for the kudos! 😊👍
Well done
Thank you!😊🙏
Nice ... thanks for sharing...Worth watching
Thank you for your nice comments, I appreciate it very much!👍😀
Great video! thanks for sharing God bless...
Thank you for your kind words!🙏Peace!
Excellent...best I've seen. A more detailed schematic of what's going on inside the box would be very helpful.
Thank you! I appreciate your kind comment. Unfortunately I can’t really do much with the schematic because I gave the unit to a guy in Mexico who couldn’t get the parts to build one. 😊👍
Great videos!
Thank you Scott! I appreciate it!🙏😀
Thank you for sharing your foam generator! Have you done any tests to see how deep of a pour you can do with the CMX or the Drexel foam? Domegaia (sp?) recommends no greater than 12" while using dish soap to prevent collapse.
Awesome 👍
Great Video. I'm new to air crete so this was a great tutorial.. Thanks. Great design on the foam generator as well, very nice job. Just one suggestion for your foam generator construction. I didn't see a Ground wire going to the aluminum enclosure. I may have missed it, but if not, you might want to add one to limit the chances of shocking yourself in wet environments. : ) Safety First! :)
Hey, thank you for the nice comment and the safety tip! I will definitely hook up that ground wire. Good eyes!👍😁
@@PranaTech Thanks for this! Also, I realize this is a year or more old, but don't just attach a bonding wire to the case!!!
There's a dangerous misconception that bonding (grounding) is meant to be a protection for wet environments, and/or that it protects against shock!
The green bonding wire (aka ground fault wire) is attached to the motor case, just as it should be, only to trip a breaker in the case that there is a failure in the motor causing the case to become energized. If the motor case is attached to the box through the attaching foot, then bonding the case to the electrical panel is already done. If the motor is insulated from the box then that's excellent.
Attaching the box to the motor case adds a conductor directly to the ground it's sitting on. If it were wet, and the there were to be a fault that energized the box you're holding, and the box is connected to the motor case, then the energy would move through not only the green wire back to the electrical panel, but also through you, and may not trip the breaker! Electricity does not take the path of least resistance, it takes all paths back to the service panel at the same time, current being dependent on resistance.
Anyway, thank you again!
czcams.com/video/3vvvv5QVZoA/video.html
Yes, I hooked the ground up to the motor because it is isolated on rubber mounts. Thank you for the safety advice! Cheers!😊👍
I finally found the video where you recommend a different foaming agent. In later videos it shows you using drexel. Did you end up going back to drexel? I want to buy my foaming agent but want to get the best. Thank you for all of your amazing information.
genius!
Thanks! 😊👍
Awesome video and design, I am new to aircrete and this is the best one I have seen (hat off to you sir!) definetly I will be building mine inspired in yours, just one question: whats the CFM and tank size of your compressor? greetings from México!
Hello Jorge, the smallest size I have run this unit with is a compressor that was 4.5 CFM @ 90psi output and had a 30 gallon tank and it was able to keep up with no problem. Let me know if you need any other information. Paz mi amigo!🙏😁
Great video! Thank you for sharing your plans and ideas. Question - what type of pump should one look for? Would a self-priming diaphragm pump work? Or are there better terms to search for?
Hi JW! Yes a self priming diaphragm pump is what I used. I have some links in the description for a couple pumps that would work. There are great deals on a regular basis on eBay for high quality diaphragm pumps. You basically need one that will be able to output 60 psi or greater would be even better. Mine has a 90psi capacity and puts out 1.6 liters per minute. I also built a larger version that uses a air powered double diaphragm pump and puts out a lot more foam. You would need a decent size air compressor to run that version though. Hope this helps. Let me know if you have any other questions. 😁👍
Thanks, Don for all your generous learning and support. It's amazing that you're so giving of your time, talents and information. I went ahead and purchased an air compressor and the shurflo pump you originally mentioned. I now see your constantly improving especially with your high output design. Question. For now, I'm going to stick with the California Air Compressor because its quiet. At just over 5 CFM at 90 PSI. Would the heavier duty pump (or equivalent) you mentioned above be the right choice for my air compressor? Thanks so much Don. Weldon
Hi Weldon, thanks for your very kind comments! They are greatly appreciated! Ok, so that compressor will work very well with my original smaller design but will be ok for smaller batches with my new high output design. I tested my new high output foam generator at work and their compressor is a 4.5 CFM @ 90 psi 30 gallon tank unit. It worked great for about 4 gallons of foam solution and was struggling for the last gallon to produce good foam. This would only come into play if you were doing large batches of Aircrete and needed a large volume of foam to match. That 4 gallons of foam solution made well over the top of a 55 gallon drum of foam so if you are doing smaller batches of Aircrete your compressor will work great because while you are mixing up a batch, you compressor can pump back up and you can do it again. Now if you want to dose an entire cement truck worth of Portland cement, you are certainly going to need a bigger compressor.😀👍Don
@@PranaTech That's fantastic news!. I meant what I said about you, Don! Thanks for everything your doing. I'm looking forward to your future work with hempcrete in combo with aircrete. I live in Vancouver BC. Change is slow and arduous from industry-standard practices. It's going to be a long battle to change any code up here. I'm sure you can relate in the States. FYI; there is a 300,000-acre hemp farm that will be in full production by 2025 in northern BC. They plan to ship hemp to ports worldwide. Lastly, I'm hoping I could email you to the address if I have questions? I'll keep it short... Again, I don't want to take up too much of your time but appreciate anything you can offer. Sooner than later, you won't have the time to answer questions due to your continued success:)
Hi Weldon, glad to help anytime! My email is pranateq@gmail.com and feel free to ask all the questions you want. I’ll try and help in anyway I can. I definitely believe that hemp is one of the building materials of the future. It will take a while to get it legal to grow everywhere here in the states, but I believe it is coming. Talk to you soon.😀👍
Sir, i want you to build this for me, am in Ghana i need this compressor sir.
Good good video!
Thank you🙏😊
Have you ever made Aircrete with refractory cement?
Hi Randal, no, but I have thought about that for insulation for my brick pizza oven that I’m planning to build.😁👍
Are there any difference or recipe advice you can share
I’m thinking of a wood fired oven use for aircrete.?
I think it should be pretty close to the same as regular cement as far as recipe goes. I was going to use fire bricks for the inner lining and then pour Aircrete in over everything for the insulation layer and then probably stucco the outer layer for durability. I’ve thought about this a bunch and I’m not sure if the refractory cement is even needed but it would certainly insure that that insulation layer doesn’t degrade over time from the heat.😊👍
Very helpful video and the generator looks really neat!
I'm planning on building my own based upon this explanation :)
Maybe I missed it, but could you provide the widths of the tubes and connectors?
EDIT: ah if anyone is searching for it, parts are in the description!
Thank you! If you have any questions when you begin building yours, just leave them in the comments and I will try and help. 😀👍Don
@@PranaTech I do have a question actually. Here and there I read that 90 PSI is required. Haven't read anywhere why though. Could you explain?
The Shurflo pump is rated at 90 PSI, but I can't easily find a pump with those specs here in the Netherlands (only Chinese crap from Aliexpress). So I'm reworking your design a bit to make it suitables for Dutchies/Europeans ;) and therefore I'd like to know if it's really required.
Hi NM, so I copied the pump from domegaia, but after using it for a while now, most of the time I set the air pressure about 55-60 pounds per square inch or 380-415 Kpa in metric. So I really don’t think you need a pump that large to make good foam. A pump that would output 60 psi should work just fine. It really just needs to balance with the air pressure so they are equal at the outlet Y. All of this depends on using a foam wand the same size as the one in my how to video. I had made a larger one earlier and it was too big for my generator to produce good foam so I had to downsize. The gallons per minute though should be at least 1.5 gpm or 6 liters per minute. Hope this helps! 👍😀Don
I just built a foam generator so that I can experiment with making air Crete. I chose to use Ajax dish detergent for the test just because I have it already and on my first test I used 6 ounces of soap to 1 gallon of water and the foam comes out pretty nice but I’m still experimenting. I haven’t tried it yet but I also have been told that adding glycerin to the soap helps with holding the structure of the bubbles. I will do a test
Hi Ben! That’s great! Glad to see others working with this stuff! I haven’t tried the glycerin trick yet but I’ve heard about it. Be curious to see what you find with it.😊👍
@Prana-Tech ok so I picked up some glycerin from Walmart but I’m definitely going to look for a larger amount for a way better price. At 6oz for $5 plus tax is not going to be cost effective. originally I had mixed about 4 ounces of Suave to 1 gallon of water I tried that and I made a really nice foam but then set my timer for one hour just for an example and after one hour my foam had dropped by about 4 inches in the 5 gallon bucket this is without the glycerin! I did a second test with approximately a quart from my one gallon of mix suave daily clarifying shampoo solution I had made but in that quart I added 1 ounce of glycerin and 3 ounces of clear light corn syrup because that is what I found online of how to make homemade bubble solution so I was thinking well if it makes quality bubble solution why wouldn’t it make nice foam. Well I am pretty pleased with the results after one hour and my 5 gallon bucket of foam has not even a drop and inch and it is still level to the top of the 5 gallon bucket but the only thing is and it’s acceptable is that the foam definitely gets more airy ( loser more open bubbles) the longer it sits though it doesn’t lose its height.
Hi Ben! Interesting results! I’ve been experimenting with this stuff for a while now and in my experience the smaller the bubbles the more effective the foam solution will be and the more durable it will be once mixed with the cement. The closer you can get to shaving cream consistency the better. You want a very dense foam with the smallest bubbles. The larger bubbles just pop when mixed with the cement. Hope this helps! 😁👍
Dude good video thanks and I can't believe someone did a thumbs down on this video thanks again
Hey Boo, thanks man! Yeah, there’s always a few out there that just can’t be pleased.🤣👍
@@PranaTech ain't that the truth lol so I'm going to making some Aircrete soon was wondering if you think a electric transfer pump would be strong enough to transfer the Aircrete from the drum into the moulding you want to put it in
Well, Aircrete doesn’t do very well going through pumps. It tends to pop the bubbles and make it collapse. The only kind of pumps that work well with Aircrete are peristaltic hose type pumps and screw auger pumps because they are gentle on the bubbles. Hope this helps! 👍 Don
@@PranaTech thank you I'll look into that
@@PranaTech by hose type pump do you mean like a eco flo thermoplastic drill pump
It's possible to use the foam to make bricks and tile with pigments colors ?replacing sand I enjoy watching U videos u got do much knowledge I appreciate you blessings
Hello Antonio! Yes, you can make colored bricks, pavers, tiles and small walls up to one meter tall per section. Thank you for your kind words! Blessings to you my friend as well!🙏😁
Cool design, though given the tubing is identical in color, makes it hard to tell one from another. I would use a couple different sharpies to provide contrast visually.
Hey, that’s a great idea! Or use some different color electrical tapes on the ends.👍😀
Great video. I have watched some of your other videos too. I am now seriously considering giving this a go in my next build. Would you mind giving me some idea of where economics of making aircrete. How much cement is required per 100 standard size block for example
Good morning! I’ve actually been working on a new method for making Aircrete chemically. This way you need no pump or foaming agent and it just rises like a cake. I’m in the process of making forms for my blocks and I should have a video out soon detailing the process and recipes to do the mix. 😊👍
@@PranaTech That sounds awesome. Can't wait!!
What did u use the 3/8 to 1/4 female to male fitting listed in parts list for? Tube for want u mentioned is 1/2 inch. Did u use the same tubing for inside the generator?
Hi Alonzo! I believe I used that fitting to reduce the outside push lock fitting to the inside hose transition. I think you could eliminate it if you just use a 3/8 O.D. Barb fitting with a 3/8 npt female on the other end. Yes the inside hose is all 1/2” tubing as well. 😊👍
Great info. I really enjoy all of your videos. I am looking forward to going Aircreat and would like a few suggestions. Could you please recommend the formula of Richway foaming solution, water and cement to make a 45 gallon mixture.
Hi Mento! For a 45 gallon mix, I put 4 ounces of Richway concentrate into 5 gallons of water for the foam machine. I then put 6.5 gallons of water into a 55 gallon container I then start to slowly blend a full 94 pound bag of Portland into the water until fully incorporated and smooth. I then fill up the container with foam up to the 45 gallon mark and then slowly blend the foam into the Portland cement mix until just fully blended and then pour into your mold. 😊👍
@@PranaTech Thank you for your timely response. That was very useful information. One more question. In a rough estimate, how much forms can I get from the 45 gallon mixture when the forms are 48 in X 24 in X 4 in?
Hi Mento, the foam gets beaten down a little by mixing into the Portland so depending how much you mix it probably about 1.5 of your forms will be filled because your form is right at 20 gallons. 😊👍
@@PranaTech Thanks you very much. Really appreciate your response. Now I know how much Freeway solution to buy. Thank you lord for this channel.😊
Anytime! Just let me know if you have any other questions. 😊👍
It seams the best foam should have the consistancy of shaving cream?
Question please. I found the pump you used and it is really expensive. Do you know if a pump wirh 45 psi will work out will it have problems at the venturi and back flow.
Hi Surly Dog! You need at least a 60 psi pump for my design to work. I have updated my parts list in the description so there are two pumps on Amazon that are fairly affordable. I purchased mine used on eBay and you can still find them if you search diaphragm pumps on there. 👍😊
Hi. Great video. Your schematic shows air hose connection to compressor. Is compressed air needed or just the Venturi pressure as you mentioned on the demo?
Hi Ahmed! Yes it needs at least 55-60 psi to blend and expand the foam solution in the wand to make the foam.👍😁
Great information thanks! Just curious about how thick a block can be cast using aircrete before it’s own weight causes the foam to start collapsing. Most demos I’ve seen are only a few inches deep, it’d be handy if thicker forms are possible.
From what I have read, you can go to about 3 feet tall in your mold before the weight is too much for the bubbles. 😊👍
@@PranaTech Cool, thanks for the reply! That’s actually quite a bit more than I expected.
That foam doesn't look bad ...but I think it needs to be thicker/firmer. May try adding a few more scrubbing pads???
Hi Jimmy! I’ve tried less and more pads. I made a newer design wand with my new high output generator and it has an expansion chamber after the pads and this helps it a bunch. Check out that video. Foaming set ideal at about 17:48 in the video. czcams.com/video/L-SAHq9X9QQ/video.html😀👍
Cool
Wow. You are a handy genius. I have a question for you. I noticed some CZcamsrs use a thickener when making their aircrete. Have you tried using any thickeners, And if so, did you feel they made a difference? Thank you so much for sharing this valuable information. God bless you.
Good morning! The only thing I’ve tried was glycerin and it did seem to help some. What I found the most effective was using a foaming agent specifically designed for Aircrete. This solved 95% of my problems. Vermillion is by far the best that I’ve used. Here is a link www.vermillionassociates.com/varimax-concentrate.html 👍😊
@@PranaTech Thank you so much! I absolutely love your videos on this subject!
Thank you! I’ll be coming out with a video soon about how to make a chemically produced Aircrete. I’ve been experimenting with it for a while now and I like it even better than the foam injection method. 👍😊
I appreciate your videos, others show their machine and offer it for sale, yours is truly aimed at the DIyer. I think the link you have for the 110 volt solenoid is wrong as it is now going to a 12 VDC solenoid. Thanks again.
Hey, thanks for your nice comments and thank you as well for letting me know about the bad link on the solenoid!👍😁Don
@@PranaTech No worries, glad to help and thanks again for doin what you do… Do you know if anyone makes a pump that is conducive to mounting vertically rather than horizontally.
I think these diaphragm pumps can be mounted any direction you want. I’ve seen them mounted in RVs upside down and vertical and they work great. 👍
@@PranaTech Thanks
Another question if I may, concerning the in and out fittings on the pump they look like they are QD do they come with the pump or do I order them? What are they called? The motor seems to be around 150 but I don't know how to verify the in and outlet. Thanks again..
What air pressure ranges are you setting regulator... Somewhere near the 90 PSI of the solution pump?
Hi there, I usually run the air pressure right at 55-60psi and that’s where it usually makes great foam.😊👍
I wanted to understand how do u know how much is the air pressure in the mixture. Or if there is a way to know what's the air to liquid mixture ratio. Of the foam
Hi Noel, I use 55-60 psi of air pressure to make shaving cream consistency foam. The foam consistency is the important part. Once you have your machine dialed in with air pressure making good thick foam, you then can adjust the density of the Aircrete by how much volume of foam you add to your mix. If you watch my other video on how to make Aircrete the right way, it tells you how to measure the density through sampling you Aircrete mix. Here is a link czcams.com/video/q5xqT2sFGdI/video.html 😊👍
can you please explain what the regular does, isn't enough that there is a regulator on the air compressor? Thanks.
Hi David, It allows you to fine tune the air balance with water volume right at the generator. You could get away with just the regulator on the compressor, but having one on the foam generator allows you to fine tune while producing foam without running back and forth to the compressor. 😀👍 Let me know if you have any other questions. Don
Thanks for the video and schematic - what volume water pump are you using ?
Hi Cass, the pump I’m using is 1.6 gallons per minute at 90psi maxed out. I usually run the air at 55 to 60 psi and so the pump only needs to overcome the air pressure. Any pump will work as long as it can put out the volume you need and overcome 55-65 psi. Let me know if you have any other questions.😊👍
Great video dude thanks for the information
Now that I have built the foam generator and the wand what formula would you use to pour a panel 4’x8’x3 1/2” thanks
Hi Bryan! Congrats on building your generator! It’s always cool to see others build stuff and have the information spread. Ok, so Aircrete is pretty fragile when it’s only 3 ½” thick. To get that to not break when you take it out of the mold is going to be tough. I’ve never tried a panel that large before, but I’ve had my own challenges with 2’x4’ panels, so bigger is only going to get worse. Two things you could do to increase strength would be to use fiberglass fibers added to the mix or short chopped hemp fibers. These would add a lot of stability and shear strength to the Aircrete for a panel that large without adding a ton of weight. You could also add a layer of scrim cloth to the middle of the panel like they do with concrete counter tops. You pour half the depth of the mold and then lay the scrim in and then pour the rest of the Aircrete in slowly so you don’t sink the cloth to the bottom. Just some ideas as I said because I’ve never tried anything that large before. I would love to see some pics of your progress if you get some done. Send them to my email at pranateq@gmail.com 😀👍Don
@@PranaTech Thanks Don
I will be using fabric and metal studs as the mold
I would like to know the yield of aircrete using the formula 94# Portland cement 6 gallons of water and 40 gallons richway foam or the recipe you use
That recipe will yield about 6 cubic feet of aircrete.👍😁
@@PranaTech thanks don
I may cut it down to 2x8 so it’s a little easier to handle
I appreciate all the information and advice
@@bryannapier3354 7.48 gal per CF so 40 gallons yields 5.35 CF . Your panel is about 9.3, so 2 batches (bags) to fill. Good for the fill half, add fabrice and then top off.
Very inspiring, wouldn’t it be wise to add a check valve right after the solonoid valve? This way water wont flow back into your air regulator in case your compressor fails or you forget to connect it somehow. I’m using a standard y-fitting so am perhaps more concerned with this issue than you need to be. Cheers
Martijn, that’s a great idea! I have been getting water coming back through the airline inlet when I flush the system after use and then I have to flush with air again to make sure there isn’t any liquid left in the system. A check valve would solve this issue completely! Thank you so much for this! Much love to you my brother! 🙏😀
Thank you for the details, Where is the air compressor.....
The compressor is in the shop. I just ran the hose out to the foam generator.😊👍
If I understand correctly, the foam solution is forced into your output hose at a constant 90psi and 1.6gpm because these are the pump's non-adjustable settings. Apparently this makes your foam generator very simple to operate -- because you've eliminated all the variables associated with the foam solution, thus leaving you with only one adjustable parameter -- air pressure/volume which you can easily control via your regulator. Genius!
Did you buy the CMX™ Foam Concentrate directly from Richway? If not, where did you get it? I've searched for it on the Internet but haven't found any retail sources, distributors or dealers.
Hi Fred, you are pretty close on the operation of the generator. The only thing that I realized about these pumps is that they boost up to 90 psi based on the pressures of the system. When I turn the air off and run just the pump to flush the system it probably only puts out 25 psi but as soon as I put my finger over the end, it will boost up all the way to 90psi if I could hold it. So it sort of balances the flow of water to match the air pressure where it mixes in the y before it comes out the front of the generator. The CMX solution I purchased right from Richway. Just called them up and ordered it over the phone. I think it was $50 a gallon. It costs more than the Drexel foam but it is way more stable when mixing with the cement. I made some aircrete with it yesterday and it was the best stuff I’ve used. It mixed smooth and creamy with small bubble structure. I made a video of it and I’m going to upload it today. Thanks for the comment! 👍😁Don
Hi Don, thanks for the clarification. Since your pump basically matches your air pressure it should be possible to use only an air compressor to power a foam generator of a different design. This would require a pressure-rated vessel to contain the foam solution, but it would eliminate the cost of the pump and the use of electricity in a wet environment.
To mimic the performance of your generator without a pump, two air regulators might be needed, one to pressurize the solution vessel at 90psi and another set to 65psi to match your regulator air pressure setting. This setup would also require a valve to control the rate of solution dispensed, or maybe a piece of copper tubing crimped enough to limit the solution outflow to 1.2gpm (more or less) at 90psi thus matching your pump's fixed volume output.
I've seen videos of people building foam generators without pumps, but usually they make their own solution vessels out of PVC pipe. This can be problematic because they all want large pressure vessels, but large diameter PVC pipe is weak, so they use long pieces of small diameter pipe instead. This makes those generators inconvenient to fill and unwieldly to use and store.
I think the benefits of your generator design are that it is very small and easy to move around, easy to control with only one regulator and a single on-off switch, and it can actually generate foam non-stop from a container much larger than a 5-gallon bucket if you happen to need that much -- no pressure vessel required.
I'm wondering if you normally set your regulator at 65psi as noted in your video, or have you been able to produce excellent foam at lower air pressures with certain foam concentrates on a repetitive basis? For example, would you ever want to be limited to 50-60psi air pressure? Or do you absolutely prefer the ability to use higher pressures? Here's why I ask:
Most DIY folks seem to be using lower pressures with their generators (which do not use pumps of course) yet they are claiming to produce great foam in many cases. My thought here is that if your generator can produce excellent foam at lower air pressures, a cheaper Shurflo pump could be used, perhaps one with a 60psi rating, and this would lower the build cost. Does this possibility seem practical or foolish based on your experience making foam?
Hi Fred, I think you could easily get away with a lesser psi pump if it could still produce the 1.6gpm. I bought the pump used on eBay for like $35 and it has worked out great so far. I have played with running the air pressure up to 90 and it makes great foam with very little density. For Aircrete to be structurally effective, you want to take a 5 gallon pail full to weigh 3 to 3.5 pounds of foam.(not including the bucket) To get this kind of density I had to drop the air pressure down to 60-65 psi and essentially make wetter denser foam. Knowing this now, I probably could have gone with the lesser shurflow pump as you have surmised. The pressure vessel foam units were just too complicated and unwieldy for me. Too many hoses and valves and constantly filling reservoirs. My plan is to build my own dome home out of Aircrete and so I will be building a much lager version of this system that I can use to inject the foam inline on the output side of a peristaltic concrete pump that I am designing, and eliminate the cement mixer from the equation. Just have a cement truck deliver slurry into my pump and then pump Aircrete directly into my forms. The new larger pump will be an air driven dual diaphragm pump. I have a bunch of projects in the works. Should be some very cool videos soon!😀👍
Hi @Prana-Tech, I built my generator exactly as your schematic shows, the only differences are the pump model (mine is 2 GPM, 100 PSI) and the Y fitting, which I bought on Amazon (a 3/8 in barbed Y connector).
My problem is that air from the compressor goes into the pump through the Y connector when I turn my machine on. After a while I am able to get the water to flow through the Y connector and foam is generated, but the air pressure never goes above 60 PSI. My air compressor is a 150 PSI one, and ir cannot stay above 60 with this setup. Adjusting the dial on the air regulator doesn't help - at max it stays at 60 PSI. Obviously when I turn off the machine the pressure goes up on the regulator, as the compressor is still pumping air at 100 PSI and the solenoid is closed.
What am I doing wrong? How can I get my air pressure to go above 60 PSI?
Hi Marco, ok so the procedure I use during startup is to not hook up the air until I have the liquid pump primed. Once I have flow, I hook up air and this eliminates back flow of air into the pump. If you don’t like this, you could install a back flow valve on the pump side of the Y so the air can’t get to the pump. The air pressure issue may be due to the size of your compressor not being able to keep up with the amount of flow that is needed to run your foam generator. The smallest compressor I’ve used my generator on was one at work that puts out 4.5 cfm at 90psi and a 30 gallon tank. I really haven’t experimented with what the minimum size compressor you will need to run this generator, but if you are less than 4.5 cfm then this may be the problem. What size compressor do you have?
@@PranaTech thanks for the answer above. I've never seen anyone mentioning a minimum CFM required for great foam generation. My compressor can sustain 2.6 CFM @ 90 PSI. Do you have any information as to what is the minimum CFM requirement for making great foam? Is it 4.5 as you noted above?
Well, I never gave it much thought until I built the larger high performance one last month. My compressor at home is an 8 cfm @ 90psi 3.5 horsepower. So it runs my small one that you copied and my new larger design that is completely air powered with no problems at all. When I brought the new larger generator to work, the 4.5cfm compressor couldn’t keep up with the demand. That compressor is a 150 psi compressor and 30 gallon tank. This is when I realized that cfm was more important than psi output. I suspect that the minimum for my small generator is probably a little less, like 4cfm but if you are going to invest in a new compressor, always get the biggest that will fit your budget and your garage. That being said, I usually only run my small generator at around 60psi for my air and this makes high quality foam. With your higher output pump than mine, you may need more cfm to match the higher gpm output of the pump. Since your pump is putting out more liquid per minute, you will need more air volume to match that output to produce high quality foam. How big is your tank on your compressor?
Superb video. I'll be making this set up to produce aircrete for my pizza oven build projects and giving you a shout out on my channel when I do. Thanks for taking rhe time to upload, much appreciated.
Awesome! A wood fired pizza oven is on my list of projects as well😀👍
@@PranaTech I'm also considering a wood fired Pizza oven which is what led me to discovering the world of AirCrete. I think I may do a dual fuel with a thermocoupled Propane heat source to facilitate better control for long controlled projects like low and slow for meats. I would think the thermal mass would be very conducive to that.
That sounds like an awesome idea with the dual fuel setup! You could even set it up with an electronic control for temperature and plumb in a pilot light and solenoid for gas and have it maintain an exact temp for as long as you wanted.😀👍
@@PranaTech That is my plan.
Nice! 👍
How much of that solution is water versus other chemicals (percentage wise)? And how safe are those chemicals to use? Do you need to worry about aircrete off-gassing VOCs?
Hi Braeden, the majority of the solution is Portland cement and water. There is 4 ounces of foaming solution mixed into 6.5 gallons of water. Over the last year I have switched to a company called Vermillion and their foaming solution is completely harmless and non toxic and the best I’ve used to date. Here is a link to their site. vermillionassociates.com/varimax-concentrate.html No VOC’s with this stuff as it is completely non-toxic. 😊👍
Could you tell me the pressure the water pump is set at..90? and the air pressure 65~70 lbs.. do I understand those correctly? THANKS.. I will do my best to make one.
Hi there, the pump has a max pressure of 90 psi but it self adjusts to match the air pressure when it’s running. The air pressure is usually at about 60 psi when I’m getting good foam. 😁👍Don
Hi, your specs say that a diaphragm type pump is used. My question is that will a centrifugal type of pump work the same for the foam generator?
Hi Rico! Yes any pump will work as long as it can produce 55-60 psi of pressure because it has to be able to match the air pressure incoming into the system so it can blend into a good foam. Let me know if you have any other questions 👍😊Don
Sir,I can't find 90 psi mortor. Is ok to change another psi mortor?
Hi Ko, yes you can go down to 60 psi if you have to. Most of the time my air pressures are around 50- 60 psi so you just need enough to equalize with the air pressure. Let me know if you have any other questions. 🙏😀
Hi friend . I just saw the video I'm interested in doing it here in Mexico to manufacture. my cellular concrete. could you help and give me information please. for all your help. Beforehand thank you very much greetings from guadalajara mexico
Less talk. More pizza ovens out of Aircrete. :-P
Great new content Don, think I watched all of them since I too have a habit of looking for treadmills and microwaves :)
Question on the aircrete (which... i was making myself this afternoon)... why do you think everyone makes the slurry so wet?
Good morning Scott! Yes the pizza oven is coming right up in the project list. It’s been delayed a bit because I’m developing a concrete pump that I can pump concrete, shotcrete and Aircrete. My design will hopefully eliminate the mixer from the Aircrete blending process. I plan on injecting the foam inline just after the pump to mix the slurry and foam, that way I can just have a cement truck pour into my pump when I want to do large batches of Aircrete. I am planning on building my own dome home out of Aircrete in a couple of years and have finally found an engineer that will sign off on my structural plans.😀👍 As far as the slurry wetness goes, I’ve just been following domegaia’s recipe and haven’t experimented with a dryer mix. Have you played around with this? If so, I would love to hear any thoughts you have on this. When you mentioned this my initial thought was that it would increase strength and density up to a point but I really don’t know, just guessing. Anyway, great to hear from another Aircrete and DIY enthusiast.👍Don
We have been using 5 gallons of water and it has been working fine. I bought some foaming agent fron Richway, but haven't had a chance to use it. My main complaint with the Drexel is that the aircrete comes out with a cottage cheese consistency (smooth but lumpy). I'm hoping to CMX from Richway is creamy Smooth.
Val
I think you’ll like it! It is very consistent and repeatable without the quality issues with Drexel. I’ve been using the concentrate from Vermillion for a while now and it is slightly better than the CMX and completely non-toxic.😁👍
Not trying to be a smart-ass but what's the point of the air switch if it just comes on when you power it up and you don't have any control over it. Or does it create some sort of resistance that's needed
Hi Shayne! No offense taken at all. So I just wanted it as simple as possible when I built it, that’s all. You could certainly add a separate switch just for the air valve if you wanted and then you could control water and air separately. I usually turn it on without my airline hooked up to prime the water pump and then hook up air and start the generator and begin making foam. If you added the air switch you could hook everything up and just control it your way with the switches. Good thinking on your part! 👍😀
Have you tried adding liquid Glycerin to your foaming agent to help stabilize the foam bubbles ?
Hi Ray! No not yet. Enough people have asked me now so there must be something to it. I’ll try it when our weather warms up.😊👍
@@PranaTech what ratio should we use for Glycerine to foaming agent?
Is they any other pump that can be used ? This one I am seeing on ebay and it is very expensive.
Hi Richard! Here is a link to another one that will work. www.amazon.com/gp/product/B07TSC6V7M/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B07TSC6V7M&linkCode=as2&tag=pranatech-20&linkId=b77db5386ca45284fd5ee21f29cc63c6. This one is less expensive. You can usually find them used on EBay for reasonable prices and they are extremely durable pumps so even used ones last for years. 😊👍
About what is you dimensions of your aluminum case you made? Thanks
Hi Jay, the box is about 12” long by 8” wide and 10” tall. 👍😁
👍👍👍
Thank you for these aircrete videos.
I'm wondering if you think a 60 psi pump be sufficient?
Hi L.S. I think 60 psi would work as long as it was a quality pump that can maintain that pressure constantly. I usually have my air pressure set at 55-60psi so the pump has to be able to balance that much pressure to be able to make good thick foam. If it can’t maintain that pressure, it will be fighting the air pressure and not getting enough water/concentrate into the mix and you will make a lower density foam that won’t be optimal for mixing Aircrete. Hope this helps and let me know if you have any other questions.👍😀Don
@@PranaTech Thanks for the reply, I really appreciate it.
No problem at all, anytime 👍
Hi, nice project...Prana, I bought all the compones for the generator, but unfortunate , the SOLENOID CAME WITH 2 BLACK WIRES,,,,WHICH ONE IS HOT
Hi Nelson! It won’t matter on a solenoid. It is just an electromagnet so being energized is all that matters. 😊👍
@@PranaTech Thank you
No problem at all! Let me know if you have any questions when you get to building it. 😊👍
I just did a quick calculation, your foam comes at 7 cents per gallon for foaming agent, if that is of interest.
Hi Jan! Thanks for information. I never worked it out but I did know that it is very cheap to make. 👍😊
Hello, I recently purchased land in New Mexico and I live in PA. I want to experiment with aircrete here in PA and make a small dome to see what and how quickly I can build a small structure. I was about to buy a foam machine but I watched your video. I would be interested to attempt to make your foam generator. Would you have a complete part list of your foam generator?
Thanks, John
Hi John, I will put a parts list together this morning and put it in the description today when I get it finished. I will reply again when I get it posted. Thanks! 👍😀 Don
Hi John, I put up links to the parts you will need for the generator in my description. Hope this helps and feel free to ask any questions you may have in the comments section. 😀👍
Great videa.
How do you know the expansion rate? Is there any way to figure it out. Expansion rate with any foam generator
That’s a good question? I’m sorry but that is way above my qualifications.😊
@@PranaTech Thank you very much.
how much did you dilute CMX foam agent to Water ? Thanks
I usually do 40 to 1 for the ratio.😁👍
Are you going to build something out of the aircrete? And, what liquid soap did you say was best?
Hi there Juniverse! The best foam solution that I’ve used is from Richway. And yes I have a bunch of aircrete projects in the works. 👍😁
Would be interested in his latest version... selling a complete unit.
How much PSI are you using max on this system? Thank you 😊
Hi Jim! 60 psi is about the max I ever use. Most of the time I run right at 55-56psi. 😁
So did the rich way tracmark end up working better than the Drexel?
Yes, it works way better! No more collapsing foam and intermittent failures for no apparent reason. I have also found an even better product from a company called Vermilion. There’s is even better and nontoxic 😊👍
@@PranaTech thank you for replying. Ironically I had just contacted vermillion
Ha! Great minds think alike! 😁👍
Great work boss, how much to have you build me the generator? A wood box would be fine to on the cheap. I’m in MN. Lastly I’m curious how the shrinkage changed when you used the cement? Did you have to refill after the shrinkage again?
Hey, thank you for your kind comment and interest in my foam generator. Unfortunately I don’t have time to build these generators but mine is basically a copy of the Dome Gaia little dragon generator. If you can’t make one yourself, you could always buy one of theirs.

I realized that I didn’t answer your second question. I don’t have any shrinkage problems since I started using Richway or Vermilion foaming solutions that are designed for aircrete and have much stronger bubbles.👍😊
Are you still in Tucson? If so I’d love to meet you in person to pick your brain. I’ve been working on a concept using ICF block but I think aircrete could
Be a better solution

The pump you link here is not available right now. Is it ok if the pump is 130 PSI ?
Hi Kamal, yes, 130 psi will work fine. Thank you for letting me know that the pump is unavailable. I’ll try and update it to a newer link.👍😀
@@PranaTech you are welcome and both of your pump links and not available . Thank you.
Do you feel like you've gotten a superior air crete using this foam as opposed to Drexel foam?
Hi Scott! Yes, a much more durable and consistent foam that was designed for use with Aircrete. Drexel is just ok and I had regular problems with collapsing Aircrete and consistency issues. Drexel is designed just for farmers to mark their fields for crop dusting. Ridgeway is far superior foam. I’m also using foam solution from a company called Vermillion and it is even better than Richway and is nontoxic. 👍😁
@@PranaTech Thanks for the reply! This is great information to know considering I kept hearing that Drexel is the best foam. I really appreciate your efforts to help others be successful!
I am interested in that machine
Hi Singa! I don’t sell the machines, I just make them so I can show others how to make them. 👍😀
Is this strong enough for a two story building?
Hello! Aircrete is not really strong enough for two stories, but there are stronger variants of the technology known as Aerated Autoclaved Concrete or AAC that is used in Europe and is available here in the United States as well. 😊👍
Would this work t shot concrete to the wall?
Hi there. No, Aircrete is too runny to stay up on a wall.👍😊
