Do you have links to those items?

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

Breathing Gas is classified Grade E

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.

Hi, can you tell me what you fill your filter with? I'm experimenting with the ratio of molecular sieve and activated carbon, in a 32cm filter, so far 70/30 is giving almost odorless air. I'm using Royal Purple fully synthetic oil. I use the air to deep clean my pool, average depth is 1.5m, max 2m. Done 2 hours so far with no ill effects, but I'd never use this air any deeper. I rent my gear when I go recreational diving because I live a very remote area of the Philippines and taking my own stuff is a nightmare.

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.

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 .

thank you for the tips, verry usefull.

You might consider an air dryer like what we use on commercial semi trucks they are large air dryer canisters

Have the Same setup with numerous filters . Still got a 300ppm co content . Dangerous levels in one tank. I did allow to run to 60c though . So more research to be done. And test the air professionally ... not at depth.

Do you have a link to the inline bleed valve?

did you ever get a test on your breathable air? these things diesel the oil in the compression chamber and actually have a lot of carbon monoxide in the air. how are u dealing with this?

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.

I have roughly the same compressor and the same setup for my air guns, I did get my air tested and it is, in fact, breathable air with secolube brand oil, no CO, oxygen level of 20.4, low PPM, VOC, with no odor. For reference, my scuba shop gets CO 2ppm @ 3000psi, so this diy system works ironically better (when I tested it, who knows how low it would last). You don't actually need to have a back pressure regulator to get clean air. I don't recommend anyone to do this just for safety reasons, just get your tank filled at the scuba place. This is not economical to do you would have to refill your tanks 50 to 80 times from empty to full to break even to the scuba shop $10 per tank refill. Or even more assuming you don't have to change the expensive oil or other parts don't break. Nevertheless it is pretty cool that such a small compressor can get up to such a high pressure to fill a large 60 min tank.

Do not do this. Not enough oxygen in the air for this.

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.

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!!!

Hi, I'm a commercial diver without a place to refill tanks easily, do you have a parts list for this

You can also consider an auto drain system for both the final stage and the inter-stage if you want further improvement.

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.

It would be interesting to have a power meter attached so you can calculate how much each fill costs.

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.

About how long did it take in total to fill the 80cf cylinder?

I just ordered this for mini take. Can I get your contact information please

You should be using Triester oil , Diester is really not rated for breathing

I wonder how to do tank inspection check? I'm scared the tank going explode.

I'm wondering if we need change oil regularly? How's the maintenance we need to work?

muito bom parabéns show de compartilhamento de informação

Whats wrong with the air quality after spending so much on filters?

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.

What type of oil are you using?

boring!

At the price point man ... But that looks fun!

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!

This was a fun project and it really works! Air quality is great. Many more tests to come.

Y'all need to look into it more and good groups get string silencers and carbon arrows never break and get fixed blade broadheads

were you using it incorrectly? a lot of the time the reason a bow string will bust off is because of user error, sometimes people will twist the the bow string at full draw, when they release or let the string down it can cause the string to derail off the cams, never have i once had a problem using this bow, also if you hold the bow in a strong grip this can be detrimental to your bow, when you hold it very tight and the string angles in your hand it can derail

String**

Picked this up today and shot it about ten times. Set it down in my room and the stung busted off... Cabelas will repair it tomorrow for free. Kinda disappointed

thats not a whisker biscuit, its the octane hostage rest.

Nice job Jon!
