PSA nitrogen generators are fed compressed air which goes to two vessels alternately. One vessel fed by pre-treated air produces nitrogen, and the other undergoes regeneration by depressurization, purging the adsorbed gases, and then repressurization. This cyclic process ensures a continuous supply of nitrogen. The adsorbent materials selectively capture gases like oxygen, carbon dioxide and other trace gases within the compressed air stream while allowing nitrogen to pass through. 

Both screw air compressors and centrifugal air compressors offer unique advantages and are suitable for different applications. When selecting an air compressor for high altitude installations, it is essential to consider all the specific operating conditions and requirements of the customer's site to ensure optimal and correct capacity, performance and efficiency for your location.
