How Do Oxygen Concentrators Work? How Do Oxygen Concentrators Work? An oxygen concentrator, or an O2 concentrator, sometimes referred to as an oxygen machine or oxygen generator, takes in the ambient air that we breathe and removes or scrubs out the nitrogen, leaving the other gases found in the air, most of which is highly concentrated oxygen.
An oxygen concentrator is a medical instrument that provides oxygen therapy to patients with respiratory illnesses. Oxygen concentrators administer oxygen that is purer than the oxygen in the ambient air. Oxygen concentrators have become significantly more popular than compressed oxygen tanks. Unlike oxygen tanks, oxygen concentrators do not run the risk of leaking and causing explosions or fires.
