Portable home compressor

[Brandon]

To cascade gas I guess it would depend on the duty cycle of the unit. Say to do a 5 bottle, 2000 cf system to 3000 psi would take 37.5 hrs to fill. To get the bank up to the normal 4500 psi, being conservative would take another 18.hr for a total of 56.25hr.

The cascade option is intriguing... but by time you purchase and plumb in the cascade cylinders and add additional filtration (another $3-4k), you may as well just buy a larger compressor.

For fun - assuming I could modify the intake to get a mixing stick in there, is this little compressor rated for up to 40% oxygen?

I need 600 to 1800 cfm a day when diving for 2 to 3 people.My compressor weighs under 300.Roughly $10K.

I'd need 16 of the little ones.On a small scale it's hard to beat paying the dive shop 3 to 10 bucks a fill once you figure in power consumption,filters and any extra gasses.

It definitely would be time management with that many tanks. I have never tried 40% oxygen? I would need someone in the Phoenix area to help me out. I'm willing to try. I'm not having good luck talking to the local scuba shops. This compressor is more for convenience. A lot of our customers live in remote locations where they don't have access to any fill shops and I find we are getting lazier to drive back and forth. This is just a thought--- once the tank got over 2K..if you removed the PMV valve...you could set the gauge to 3K and it would fill faster. The PMV valve is set to 2K, the gauge needs to be set for 5K to achieve 3K. It would only be practical for large tanks. I have ran this compressor in my garage for 2 days non-stop at 3k in the 115 degree heat. The compressor water tank was about 125 degrees and it worked fine.

even for an at home convenience type compressor it is just abysmally slow. You're talking about a compressor with a 0.4-0.5cfm fill rate. For things like CCR guys it may be warranted, but 3-5cfm is kind of a bare minimum for a tolerable fill.

On an average day in cave country, I will go through roughly 400cf of nitrox and O2 That's 13 hours of filling with this thing vs just over an hour on a Rix... Great idea, but if it was even a 2cfm instead of 0.5cfm it would be legit.

I do have a dual piston model that only takes 1.5 hrs to fill a tank.

 

[tbone1004]

still less than 1cfm though, which while quite a bit faster is still about half the rate it needs to be. I can get a Rix SA-3 granted used, for about the same money you are asking for the single piston, but is 3cfm and not much less portable and still runs off of 120v single phase plug.

This is our other model that we have...110 volt 5amps ,auto-stop, manual bleed,single filter, PMV valve (not shown). It is the same piston as the other model. This model goes for $1,650. I think for a 2-6 tank set up this would be fine. Very portable and light weight.

The RIX compressor weighs in at 150 lbs and it is 110 volt,but it takes a 30 amp breaker. My compressor you could put it in a suitcase and fly anywhere you want to go.I have used a pure sine wave inverter to run this compressor when i have gone camping.

What is the flow rate for this one?
