Oxygen Generators (OG)


OGSI offers a range of generators based on your requirements. They are designed for applications requiring outputs from 25 to 5500 SCFH (12 to 2360 LPM). You’ll never pay for capacity you don’t need. Non-standard generators are available on request.

Our line of Pressure Swing Adsorption (PSA) oxygen generators can deliver a constant flow of up to 93% (± 3%) oxygen at 45-60 psi. Higher oxygen pressure is optionally available.

These units are available with telemetric communication packages. The plant can be monitored from our factory to facilitate quicker service or software updates.


Energy Efficient

OGSI's plants are the most energy efficient plants on the market. Extract oxygen directly from the atmosphere and deliver it to any medical or industrial application with an OGSI oxygen generator. All you need is air, electricity, and OGSI's plants to begin generating your own oxygen on-site, on-demand, with only the electric bill to pay once purchased.

Dependable – MADE IN USA

Every PLC-controlled 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 robust manifolds, our generators operate in the harsh environments of Africa, Asia, South America and the Yukon.


Eliminate the unnecessary costs of transportation, storage and cylinder rental. OGSI’s oxygen generators are economically priced so that you can realize a return on investment within a short period of time. Supplying oxygen for as little as 3 kW/100 SCF, OGSI’s oxygen generators are the most energy efficient plants available.

Unfamiliar with PSA Oxygen Systems?

Pressure Swing Adsorption (PSA) is rapidly becoming the technology of choice for a range of applications. Call or contact us to request a personalized quotation. OGSI can provide the proper air compressor, air dryer and storage tank combination to optimize your oxygen system. We can assemble the system and test it in our factory before shipment. All components can be mounted to a steel skid and pre-wired for easy transportation and set-up.
