The CAS-Series carbon dioxide adsorbers are designed to remove CO2 from compressed air. The carbon dioxide adsorber does this by using media beds featuring 13X molecular sieve in a pressure swing adsorption process. Adsorbed moisture and CO2 are vented to atmosphere while dry CO2-free air is provided at the outlet port. Standard voltage is 115 VAC. 230 VAC is available. Standard operating pressures from 50 to 150 psig.
