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.
