How Oxygen PSA works
Ad-sorption is the physical process of separating molecules. Our Pressure Swing Adsorption (PSA) oxygen generation systems generate oxygen by separating it from the nitrogen in ordinary air. Air, of course, is 20.9% oxygen and 78% nitrogen, along with a small percentage of inert gases.
A vessel containing a molecular sieve called zeolite is filled with compressed air. The nitrogen molecules are adsorbed by the sieve material while the oxygen molecules drift past and are collected in an oxygen receiver tank.
Pressure is then released from the vessel, and the nitrogen molecules are vented to the atmosphere. At the same time, the cycle is repeated in a second vessel to provide a constant flow of gas.
