MEDICAL OXYGEN GENERATOR
HOW IS OXYGEN GENERATED?
Most components of a Medical Oxygen Generator are quite similarto Medical Air Generators. A large compressor compresses atmospheric air, which is then passed through a dryer and a series of filters. Next are the Pressure Swing Adsorption (PSA) towers where the dried and purified compressed air gets separated into oxygen and nitrogen.
The separated oxygen is further filtered, stored and delivered to medical gas pipeline systems. Duplex and High-Pressure Systems with oxygen booster for cylinder filling are available as options.
THE PSA PROCESS
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.
