AirSep Oxygen Generators use vessels filled with molecular sieve as adsorbers. As compressed feed air flows through one of the vessels,the molecular sieve adsorbs nitrogen. The remaining oxygen passes through the vessel and exits as the product gas. Before the adsorber becomes saturated with nitrogen, the feed air is diverted to another vessel. At that point, the sieve in the first vessel regenerates by desorbing the nitrogen through depressurization and purging it with oxygen from the other vessel. This process is then repeated to allow the oxygen generator to deliver a constant flow of product oxygen at 90% minimum purity. Under normal operating conditions, the molecular sieve is completely regenerative and will last indefinitely.
AirSep offers a wide variety of standard PSA oxygen systems to supply virtually any oxygen application from 12–5,000 SCF/hr (0.32–131 Nm3/hr) of product oxygen output. AirSep also designs
