摘要：
An oxygen concentrator may rely on a pressure swing adsorption process to produce an oxygen enriched gas stream from canisters filled with granules capable of separation of oxygen from an air stream. The adsorption process uses a cyclical pressurization and venting of the canisters to generate an oxygen enriched gas stream. During venting of the canisters, use of oxygen as a purge gas may improve the efficiency and lifetime of the oxygen concentrator.
