PSA pressure swing adsorption nitrogen generator, works using pressure swing adsorption (PSA for short) is a new technology for gas separation, the principle of which is the use of molecular sieves of different gas molecules "adsorption" performance differences separating gas mixtures. 

It is to air as raw material, the use of a high performance, highly selective solid adsorbent for nitrogen and oxygen selective adsorption performance of air nitrogen and oxygen separation.
