<DIV>I’m in the process of designing one and decided to go with
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>

<DIV>Here’s an example of a rebuilt Biopak. It’s the first
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>
