[PSUBS-MAILIST] CO 2 absorbent

[Alan James via Personal_Submersibles]

Brian,I have read in the past that medical grade absorbent isn't the most suitable for our application.I am not sure why, but it does say that it provides minimal resistance to gas flow. This could be required because theair is circulated by lungs. Whereas with our fans, a different grade might be more efficient.Alan

I’m in the process of designing one and decided to go withthese pre-filled containers.  I used them with my BioPak rebreather I’drebuilt to use for diving.  They worked well for that purpose. Sealed until needed and a standard size.  They show up on eBay alot.  I plan to designed and print out a casing now that I have a 3dprinter! Scroll down the page to see what I mean. http://www.midmarkanimalhealth.com/products/consumables/sodasorb  Here’s an example of a rebuilt Biopak.  It’s the firstone shown.  Most of us swapped in regulators from surplus E. Germanmilitary rebreathers as they fed .9 liters/m at ambient pressure.  You canfind them all over DIY rebreather sites.  http://www.therebreathersite.nl/06_Homebuilders/steve_z_paige.htm  Brian HughesLake Diver
