An oxygen concentrator is a device that concentrates the oxygen from a gas supply by selectively removing nitrogen to supply an oxygen-enriched product gas stream.
Two methods in common use are pressure swing adsorption and membrane gas separation.
An oxygen concentrator receives the ambient air, filters out nitrogen to retain oxygen, and then supplies it through the nozzle. Oxygen concentrators are usually capable of delivering 90 to 95 percent pure oxygen.
