AirSep oxygen systems utilize its proven proprietary technologies to produce oxygen non-cryogenically.
This technology uses an air separation process, Pressure Swing Adsorption (PSA), with molecular sieve (a synthetic zeolite), which attracts (adsorbs) nitrogen from air at high pressure and releases (desorbs) it at low pressure.
AirSep oxygen concentrators, generators, and oxygen plants use at least two vessels filled with molecular sieve as adsorbers. As compressed or pressurized air passes through one of the adsorbers, the molecular sieve adsorbs the nitrogen. This allows the remaining oxygen to pass through and exit the adsorber as a product gas. Before the adsorber becomes saturated with nitrogen, the inlet air flow switches to the next adsorber. The first adsorber is now regenerated by desorbing the nitrogen through depressurization back to the atmosphere, followed by an oxygen purge step. The complete cycle then repeats. When large-scale oxygen production is required, Vacuum Pressure Swing Adsorption (VPSA) is utilized. This process further aids the regeneration or desorption step utilizing a vacuum blower.
