Oxygen generators separate oxygen from air so that the gas can be fed into industrial processes in real-time or stored in pressure tanks. Oxygen generators are used in dozens of industrial applications ranging from gold mining to aquaculture to life support.
Normal ambient air is made up of 78% nitrogen, 21% oxygen and other trace gases like argon and CO2. In order to remove the nitrogen and trace gases an oxygen generator is used.
The smallest oxygen generators can be no larger than a 10 liter can, while industrial oxygen generators can be as large as a container. However, all oxygen generators have the same purpose: to provide a safe supply of concentrated oxygen gas.
