Standard Oxygen Generator

NOVAIR USA oxygen generator OG 100

Our tried, tested, and true “original,” the high-quality OG oxygen generator fits in a variety of applications

NOVAIR’s OG oxygen generator series is the tried and true industry leader in standard O2 generating equipment. The OG’s extract oxygen directly from the atmosphere and deliver it to any health or industrial application using Pressure Swing Adsorption (PSA) technology that can deliver a constant flow of up to 93% (±3%) oxygen purity at 45-60 psi, with higher pressure optionally available.


Every generator is assembled and tested in our North Tonawanda, NY production facility. The zeolite sieve is factory sealed in solid steel tanks, and rarely needs replacement. With very few moving parts, our generators are built to provide thousands of hours of continuous, reliable service. Routine maintenance is as simple as changing an air filter. 


From their precision-welded tank assemblies to their oxygen-clean brass tubing and valves, our generators operate daily in some of the harshest areas of the globe from near the North Pole to the penguin territory.


Eliminate the unnecessary costs of transportation, storage and cylinder rental. Our standard product line has 12 models — from 100 to 5,500 SCFH — so that you’ll never pay for capacity you don’t need while saving much money over delivery. Non-standard tailored generators are also available on request.
