Medical Oxygen Generator utilizes an ultra-porous adsorbent material known as Zeolite, or ‘molecular sieve’. The system consists of two Zeolite-filled towers, with compressed air passing through any one tower at a given time. The towers selectively trap (adsorb) the nitrogen molecules in their nanometer sized pores, letting the oxygen pass unaffected.
Over time, as Zeolite in the initial tower becomes saturated with nitrogen molecules, compressed air supply is switched to the other tower which continues the oxygen separation. Meanwhile, the saturated tower is regenerated by depressurization and oxygen flushing. In this way, the entire cycle automatically repeats – producing pure oxygen consistently.
