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.

Our Standard AS- Series Oxygen Generators can produce from 20 to 5000 cubic feet of oxygen per hour! Once you provide electricity and a source of compressed air, these dependable machines will provide oxygen for any application.

AirSep generators are designed to produce between 45 psig and 65 psig output pressure, 93% nominal purity oxygen, -100°F(-73°C) dewpoint and are available in 120 VAC or 220 VAC.

The Pressure Swing Adsorption (PSA) Oxygen Generating Process

Air contains 21% oxygen, 78% nitrogen, 0.9% argon, and 0.1% other gases. AirSep Oxygen Generating

Systems separate oxygen from compressed air through a unique Pressure Swing Adsorption (PSA)

process. The PSA process uses molecular sieve (a synthetic zeolite), which attracts (adsorbs) nitrogen from air at high pressure and releases (desorbs) it at low pressure.

AirSep Oxygen Generators use two vessels filled with molecular sieve as adsorbers. As compressed feed air flows through one of the vessels, the molecular sieve adsorbs nitrogen. The remaining oxygen passes through the vessel and exits as the product gas. Before the adsorber becomes

saturated with nitrogen, the feed air is diverted to the second vessel. At that point, the sieve in the first vessel regenerates by desorbing the nitrogen through depressurization and purging it with oxygen from the second vessel.

This process is then repeated in the second vessel to complete a cycle that allows the oxygen generator to deliver a constant flow of product oxygen at 90% minimum purity. Under normal operating conditions, the molecular sieve is completely regenerative and will last indefinitely.
