[PSUBS-MAILIST] Co2 scrubbers

[Private via Personal_Submersibles]

Hi Rick,

As always my guiding principle is to use the simplest components I can. In this case it's a little 1st stage made by Piranha Dive Manufacturing. I'd never heard of this little company but their 1st stage was so reasonably priced I ordered one just to see what it was like. Well, I liked it so much I ordered two more. This is advertised only as Nitrox ready for up to 40% O2. However, I spoke to the owner and he said the O rings, lube, and cleaning process are all for 100%, but they just advertise it for 40% as a legal CYA. It's a balanced piston design.

Best,

Alec
