What is a portable oxygen concentrator?

An oxygen concentrator is a device which concentrates the oxygen from a gas supply (typically ambient air) to supply an oxygen enriched gas mixture

inogen_one_g2Oxygen concentrators typically use pressure swing adsorption technology and are used very widely for oxygen provision in healthcare applications, especially where liquid or pressurised oxygen is too dangerous or inconvenient, such as in homes or in portable clinics.

Oxygen concentrators are also used to provide an economical source of oxygen in industrial processes, and also known as Oxygen Gas Generators or Oxygen Generation Plants

An oxygen concentrator has an air compressor, two cylinders filled with zeolite pellets, a pressure equalizing reservoir, and some valves and tubes. In the first half-cycle the first cylinder receives air from the compressor, which lasts about 3 seconds.
