An oxygen concentrator is a device that
concentrates the oxygen from a gas supply
(typically ambient air) by selectively
removing
nitrogen to supply an oxygen-enriched product gas stream.
nitrogen to supply an oxygen-enriched product gas stream.
Oxygen concentrators using pressure swing
adsorption (PSA) technology are used widely for
oxygen provision in healthcare
applications, especially where liquid or pressurized oxygen is too dangerous or inconvenient, such as in homes or portable
clinics. For other purposes, there are also concentrators based on nitrogen separation membrane technology.
