They are used industrially, to provide supplemental oxygen at high altitudes, and as medical devices for oxygen therapy .
Portable oxygen concentrator used with bottle humidifier. POCs operate on the same principle as a home concentrator, pressure swing adsorption. [6] The basic set up of a POC is a miniaturized air compressor, a cylinder filled containing the sieve, a pressure equalizing reservoir and valves and tubes.

These are the canisters which ignited and caused the fire on the ValuJet flight in Florida. The develpment of the oxygen generator is held by a Dr Hwoschinsky.
