CANISTER DESIGN CRITERIA OF CARBON DIOXIDE REMOVAL FROM SCUBA
Abstract
An empirical set of design criteria for a scuba carbon dioxide moval canister were derived from data obtained by a review of the pertinent literature. Such a device, presuming satisfactory performance for 180 min. at 30 ft. and 30 min. at 180 ft., must be capable of absorbing a minimum of 600 gm. of C02. It must also remove 75-80% of the C02 from a mixture containing 0.5 - 2.0% C02 passing through it at a velocity of 55-90 L./min. It must remove 70-75% of the C02 from a mixture containing 1.0 - 2.5% C02 passing through it at a velocity of 125-200 L./min. The breathing resistance must not exceed 1.5 cm. H20/L/sec. The inter-granular space must be at least 3.5.L.
