MX Rebreather - Radial CO2 cartridge, stand/watertrap & Canister

The canister is a rigid canister that has one sealed end and one removable end or head. The canister is designed to be as low profile as possible, will not flex at depth, fits between our double backgas/bailout/diluent tanks and houses the radial CO2 cartridge.

The Radial CO2 cartridge is a re-packable cartridge designed to take 7.9lbs of CO2 absorbing material such as sofnolime. We chose radial canister design as it gives us the best work of breathing results, or the least resistance of the gas, to pass through the materials. Of course there are always pro’s and con’s. As the canister is re-packable by the diver, one must take care to carefully pack the CO2 absorbing material to ensure no major gaps exist in the material which will allow CO2 laden gas to channel through. Radial cartridges are considered more sensitive to channeling. A second consideration is the size of the granuals of the CO2 absorbing materials. The larger the granuals, the less breathing resistances but the less time the CO2 laden gas contacts the material and therefore the less diving time the 7.9lbs of CO2 absorbing materials gives you. The smaller the size of the molecular the higher the breathing resistance but the longer you get. Generally we use sofnolime 8-12 mesh/797 to give us about 1 hour per pound of CO2 absorption time. Of course temperature and workload and many other things play a factor as to how long we get.

The canister is a rigid, anodized, aluminum canister, that has one sealed end and one removable end or head. The canister is designed to be as low profile as possible, will not flex at depth, fits between our double backgas/bailout/diluent tanks and houses the radial CO2 cartridge.

The the CO2 Cartridge is placed ontop of a small spacer or stand that also acts as a water or moisture collection area. This moisture can be a by-product of the the CO2 reaction or form an intrusion. The moisture pads are designed to absorb this moisture and protect it from traveling through the CO2 absorbing materials and then heading towards the divers as a caustic cocktail.
