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.
There are various sizes and types of stationary oxygen concentrators, but most of them feature the following: 1  Power switch: This turns the concentrator on and off. 2  A light shows you when the unit is on. 3  Flow meter: This controls the flow rateâhow fast the oxygen is delivered through the breathing device.
