these pre-filled containers. I used them with my BioPak rebreather I’d
rebuilt to use for diving. They worked well for that purpose.
Sealed until needed and a standard size. They show up on eBay a
lot. I plan to designed and print out a casing now that I have a 3d
printer!</div>

one shown. Most of us swapped in regulators from surplus E. German
military rebreathers as they fed .9 liters/m at ambient pressure. You can
find them all over DIY rebreather sites.</div>
