A gas adsorption rebreather canister containing at least one sheet embodying adsorbent material inside and a portion of the sheet spaced apart by a separating means. The sheet being arranged so that expelled gases entering pass along the canister interior substantially parallel with a surface of the sheet. The sheets can be formed with an internal screen positioned between two gas-permeable, liquid-water resistant membranes and the adsorbent material positioned within interstices between the screen members. Also, the sheets can comprise a sheet of expanded porous PTFE having a microstructure of nodes interconnected with fibrils, said sheet containing gas adsorbent material. The sheet can be covered on each side by a sheet of expanded porous PTFE. This device effectively contains the adsorption material within the sheets when exposed to vibration, air, and water. |
