What is PSA and how it works?

Generator columns are filled with molecular sieve. A product Gas is separated from clean&dry compressed air by PSA method (Pressure Swing Adsorbtion). Unwanted molecules are being adsobed by molecular sieve during pressurization phase and released during the exhaust phase. The molecular sieve is fully regenerated at the beginning of each cycle. The process is repeated and a constant production of gas is established.
