I'm a volunteer firefighter. I live in a rural area where I have to fly out my empties. I think I'll look in to this. I've just had our ten bottles replaced.
This was a fun project and it really works! Air quality is great. Many more tests to come.
did you try it on 80cf tank?
I am a Bauer and Nuvair factory technician, and the only thing I can say is that, wow, you've done your research, and you nailed all the key points. Maybe find a more effective way to do aftercooling, like using a coil of stainless tubing. And the final stage separator should be installed right after the final stage but after all the filters since moisture reduces the effectiveness of all the filters. The PMV should be something individual instead of built-in and installed after the final filter. Maybe consider installing remote air intake, dew point monitor and Co monitor as well as performing air testing to be compliant with Grade D breathing air or CSA 275.2. Also, consider replacing all the filters with a Bauer triplex.
SO that is my dilemma here Sir. i have a Poseidon "UNI" Compressor. and need to augment/replace the old filtration system, as I was told that the Filters are now Obsolete. It was built from the Bauer Compressor Head set up from the factory. If you could give any advice here, as all the USA Reps I have contacted, I believe I am up to 6 across the USA, seem to not support this small Compressor, anymore. What is a Bauer Triplex, and costs? Thanks!
You might consider an air dryer like what we use on commercial semi trucks they are large air dryer canisters
I have debated this before! Please give updates for n how the air works out, any tank issues, build sheet and costs, subscribing for this kinda info for sure!
Life got crazy busy, but I do plan to do shallow dives and disect the filters after some more use. Not really feasable for regular use and there is concerns of air quality. I plan to see about having air samples tested. But still a fun project.
@@BringYourHelmet OK, so you do not recommend any of the filters you rigged this with, I suppose, then?
In the process of setting up a Yong Heng compressor for PCP Airgunning. I removed the cigarette filter and went straight to a oil/water separator(the gold filter you see here with a drain) and a single cotton/charcoal/cotton filter. I also purchased Seccolube 500 which is similar to the diester based oil mentioned here for air purity. This is good enough for shooting
If I was going to trust my life to a compressor like this I would run this layout: compressor > oil/water separator > molecular sieve> cotton/charcoal/cotton filter> PMV valve
After doing all this, you SHOULD be safe. But if you want to be sure you can contact a lab and see if the air is considered breathing safe. They will provide you with instructions on how to send them the air.
I would advise AGAINST the current setup that he is using now, I personally think that he is using the BARE minimum for breathable air. I would rather spend a few hundred dollars on the proper filtration rather than passing out and dying underwater or getting some sort of lung disease because of the contaminants breathed in and paying THOUSANDS in medical bills.
I wasn't aware of a PMV - Thank you for informing us on that. Great Video!
You can also consider an auto drain system for both the final stage and the inter-stage if you want further improvement.
Good explanation! very interesting. I bought one but the manual is lacking.. Can you put a link to the manual. I dont find it. And the dealer doesn't answer anymore and there is no brand on it..... It looks very similar to yours even the colours are identical (but is a single step).TNX
thank you for the tips, verry usefull.
Try Filling my Aluminum 80 cf to 3k PSI. I have a Nomad I use to fill a 6cf Spare Air. Using Extra Filters on the output.
After a year how has it held up? Have you filled any 80s with it yet? How much did the whole rig end up costing? Thank you.
Awesome video thanks for sharing . I don't have a dive shop anywhere close to me so I would like to build a rig similar to yours .
A while back i bought a similar compressor and air filter and everything, but my diving school prohibited me from using it as it's impossible to guarantee that the air is healthy clean. Official filling stations are sampled and checked by a lab to prove that the air is good, and that the machinery is almost guaranteed to keep working in that clean way. If you want to poison yourself it's your own choice, but your buddy is also depending on the air quality in your tank. Which makes it rude to fill your tank with this.
I just used a Husky oil less compressor with a Horrible Freight spray paint filter and a $50 regulator and 2x 25 ft HF hoses I was down only 5.5 feet for 45 minutes in my pond vacuuming sludge off the bottom, and I had no problems what so ever. It was really cool in fact.
Will you be getting a 2L scuba tank now that they are out. Interested to find out how quick your set up can fill it.
At the price point man ... But that looks fun!
I'm wondering if we need change oil regularly?
How's the maintenance we need to work?
Do you have a link to the inline bleed valve?
Excellent build, and explanation, Sir! Would you be as so kind to provide links, or if anybody else could on the Whole Filtration system parts sources? I was lucky to find an Electric Poseidon "UNI" model 3.5 CFM Compressor. Several decades old but with maybe 10 max 80Cu tank fills in its whole life. The issue is I have hit brick walls sourcing any of the Old Filter designs as they are now "Obsolete" I searched for even NOS filters, with no luck, as well. So, like you I only wish for Clean Air going into these lungs of mine, and some directions as to what you sourced would be pure gold. I was quoted over $1,100.00 for a custom build from Bauer, who made the Compressor head section for Poseidon to begin with. Poseidon as a Company is no longer, and Bauer sort of bought them out. The USA Factory reps do not wish to support us small fries and cater to the Huge Compressor market mostly! If anyone else has any suggestions as well, I'd appreciate your input, as well! Thanks for a great understandable build, and use of your compressor! It should last you, because of your enhancements galore! Great JOB!!!
Whats wrong with the air quality after spending so much on filters?
Breathing Gas is classified Grade E
Do not do this. Not enough oxygen in the air for this.
How so ?.
@@brianredmond4919 the compressors sometimes has little combustion in the cylinder depending on the oil maybe. I run royal purple full synthetic and probably still wouldn't try to breathe it. The oxygen levels are very low probably due to the small combustions. Scuba shops have big fancy compressors and tanks probably already filled they can cascade into your bottle.
@@brianredmond4919 I saw a review on CZcams where the guy sent off the air to get tested and oxygen levels were just too low.
@@drywallman1986 what you’re saying makes no scientific or medical sense. The oxygen level is absolutely the same going into and out of this compressor. The risk with oil based “air’ compressors in terms of breathing is lipoid pneumonia… the diester oil addresses this point. The danger really is if someone tries to compress enriched air I.e. higher concentration oxygen. That’s when unrated oils, combined with pressure results in a possible explosion.
@@drywallman1986 depending on what he sent the sample container had in it before adding the gas under test and the elevation where the sample was collected can affect the results. There may be oxidation in this system, but there is no ‘mini combustion’ going on! 👌🏿😉
