AirSep’s products range from standard generators delivering 6 LPM to custom-built, large-scale industrial Pressure Swing Adsorption (PSA) or Vacuum Pressure Swing Adsorption (VPSA) systems that can produce 100 tons of oxygen per day. For over 25 years, AirSep Oxygen Generators have been a proven alternative to any other oxygen source, reliably producing oxygen, 24/7. AirSep’s high-quality products are easy to maintain, the most cost effective and the safest oxygen sources available for applications such as fish farming, thermal/chemical oxidation, ozone generation, waste/water treatment and environmental remediation. AirSep delivers innovative solutions for all of your oxygen generation needs.


Blazing New Trails!

We did not get to be an Industry Leader by following in everyone’s footsteps. AirSep Corporation is a unique success story based in NY. Over 25 years ago, our founders started a company whose main goal was to provide an innovative on-site oxygen source. Two decades later, AirSep Corporation is still synonymous with oxygen generation. Whether it is for hospitals or industrial applications like mining, steel mills, paper mills, water treatment facilities, etc., AirSep products deliver the oxygen where you need it, when you need it!

AirSep’s wide range of standard generators have secured AirSep as the leader in on-location oxygen generation. Whether you are in need of a self-contained generator, standard generator, packaged system, large plant, or simply have a specific application in mind, AirSep delivers innovative solutions for all of your oxygen generation needs.

Our customers include some of the biggest names in the gas industry: Air Liquide, Praxair, Linde, Air Products. All of our customers recognize that we have built a solid reputation for providing them with quality systems that deliver as promised!

How Does It Work?

It’s All About the Swing!

Oxygen is essential for supporting life as well as many other industrial and environmental applications. This makes it one of the largest selling chemicals on the planet. AirSep has adopted the motto: “Why buy when you can make your own oxygen?”

Oxygen exists in the atmosphere around us. It makes up approximately 21% of the air we breathe. If only that oxygen could be separated…

The technology behind all of our standard oxygen generators is the Pressure Swing Adsorption (PSA) process. It is the engine that drives the separation of oxygen from air. It is a purely physical process; there are no chemical, electrical, or other reactions in our process.

For certain specific applications, we can make a variation of the PSA process, called the Vacuum Pressure Swing Adsorption (VSA/VPSA) process. The only differences are that VPSA uses a feed blower instead of an air compressor and the absorber vessels are desorbed through a vacuum blower. The net result is a significant decrease in the power consumption of the system as a whole. However, these plants are typically only cost effective for very large oxygen capacities.
