The clean compressed gas into KPN series PSA Nitrogen generator, the carbon molecular sieve adsorb the oxygen and release the Nitrogen. When the pressure rise up, carbon molecular sieve adsorb the oxygen, during the pressure reduce to the normal pressure, the carbon molecular sieve desorption the oxygen for regeneration. KPN series system generator with two tanks, one tank adsorb the oxygen to make the nitrogen, the other one on regeneration. For that cycle switching on two tanks, system can continue to make the nitrogen gas.
