About Airsep Onyx

This oxygen generator is a self contained unit ideal for commercial use.

Onyx--9054

  • Advanced engineering.
  • Low operating cost.
  • Transportable with rollerbase design.
  • Easy to operate and maintain.
  • Time-proven reliability.
  • Successfully used around the world.

Specifically designed for reliability, energy efficiency, and ease-of-use, there are thousands of Onyx PSA Oxygen Generators currently in use throughout the world. The Onyx’s reliability, low noise level, and ability to deliver up to 95.5% oxygen concentration make it a perfect fit for many applications, in water treatment as a feed gas for some type of ozone generators, jewelry/soldering, glass work/blowing, fish farming, laboratory experiments, aquaponics, and hydroponics.

How It Works

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 process. The PSA process uses molecular sieve (a synthetic zeolite), which adsorbs nitrogen from air at high pressure and releases it at a 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 products gas. Before the adsorber becomes saturated with nitrogen, the feed air is diverted to the second vessel. At the point, the sieve in the first vessel regenerates by desorbing the nitrogen through depressurization and purging it with oxygen from the second vessel.

The 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.
