Dave thanks for the reply.I have heard that they use membranes in submarines to scrub O2 then they vent the O2 out into the water, out of the loop. This is similar to what I want,exept I would like to introduce Helium into the mix,Do you think this is possible
Larry
What I would like to do is be able to remove CO2 from a Helium Oxygen Nitrogen breathing mix without relying on a sodalime chemical scrubber. can anyone on this site help me. Expired gas would be approx 5% CO2 on every breath. approx 1 liter per minute
