Oxygen Concentrator

We just got one of these in at work. Great device for concentrating over 95% oxygen from ambient air at a rate of up to 5liters/minute. Although expensive (about $4k)

You would probably have to run it in conjuction with a haskel to get it to any kind of pressure, I'd guess.

There is a company making a booster to fill portable medical oxygen cylinders from this machine. I see it as a emergency medical oxygen source for scuba instructors or the truck ride to the chamber.

Yeah, that would be a great use, especially way offshore !

I am not sure on the separation process but it should be noted in other systems there has been issues’ reaching above 90% and there has been problems with inert gas buildup.

Jeff describes in this article that they averaged 90% O2
and 5% ARGON in the breathing gas.
