  • OXYGEN CONCENTRATOR APPARATUS AND METHOD HAVING FLOW RESTRICTED COUPLING OF THE CANISTERS
    Publication number: 20150059742
    Abstract: 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. The oxygen concentrator system may include one or more flow restrictors to allow controlled release of oxygen enriched gas between the canisters.

  • Oxygen concentrator apparatus and method with an oxygen assisted venting system
    Patent number: 8915248
    Abstract: 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.
