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.
As a general rule, oxygen concentrators produce oxygen at purity levels between about 90-97 percent at most. This is variable, however, with regard to certain factors such as â¦elevation. At lower elevations, oxygen purity will be higher. If you are looking for an oxygen concentrator for personal use, www.VitalityMedical.com has a lot of good information on their blog.
