AirSep Oxygen Generators provide instant oxygen on demand, eliminating the oxygen deliveries or the transportation and storage of pressurized, volatile oxygen cylinders on premises. Provides all the oxygen needed for most jeweler’s torches.
  • Generates 93% nominal oxygen concentration.
  • Generate oxygen at half the cost of cylinders or liquid oxygen.
  • Two models are available: the portable Onyx (on rollers) for one-person and smaller shops and the commercial grade Topaz Plus for production shops. Topaz Plus is wall mountable and includes oxygen delivery and cycle pressure gauges, and high temperature, ozone-resistant process tubing.
  • Larger models available. Please email us for details.
Both the Onyx and Topaz Plus utilize a molecular sieve to separate compressed air into nitrogen and oxygen, allowing the oxygen to pass through to your torch line. The molecular sieve is completely regenerative and will last indefinitely making AirSep the most user-friendly oxygen generator on the market.

Both generators require minimal regular maintenance, limited to cleaning the system’s particulate filter and replacing filter pads. Filter pads are sold in packages of 5.

Air Oxygen Generators are CSA and CE approved. 1 year manufacturer’s parts and factory labor warranty.

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 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.

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.
