Quality and long-term value are built into every AirSep product for total customer satisfaction. AirSep’s commitment to world leadershipin expertise, capabilities, and products inspires technologically advanced, innovative solutions for every aspect of oxygen supply needs.

Pressure Swing Adsorption (PSA) and Vacuum Pressure Swing Adsorption (VPSA) Oxygen

Air contains approximately 21% oxygen, 78% nitrogen, .9% argon, and .1% other gases. AirSep Oxygen Systems separate this small
percentage of oxygen from compressed air through a unique non-cryogenic process. Both the PSA and VPSA processes use molecularsieve (a synthetic zeolite), which attracts (adsorbs) nitrogen from air at high pressure and releases (desorbs) it at low pressure.
AirSep Oxygen Generators and Oxygen Plants use at least two vessels filled with molecular sieve as adsorbers. As compressed orpressurized air passes through one of the adsorbers, the molecular sieve adsorbs the nitrogen. This allows the remaining oxygen topass 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. Under normal operating conditions and with proper system
maintenance, the molecular sieve is completely regenerative and will last indefinitely. The Vacuum Pressure Swing Adsorption (VPSA)
process further aids the regeneration or desorption step utilizing a vacuum blower.

Self-Contained Generators

For unique applications, AirSep offers a range of completely self-contained
oxygen generators equipped with air compressors. With the exception of theCentrox, these generators require no special installation. Simply connect theoxygen outlet to your oxygen distribution system and the power cord to agrounded electrical outlet. Turn the unit on and set your oxygen flow rate.

relatively low pressures are needed. They supply sufficient oxygen for ozone generation,
jewelry manufacture, glass work, and various brazing applications. In comparison, theCentrox and Reliant are ideal for use in applications that require oxygen pressures of 12-50 psig (85-345 kPa) at 8-15 LPM.

Standard Generators

AirSep Oxygen Generators eliminate the expense, inconvenience, hazardous
handling, and storage problems often associated with purchased liquid or highpressure cylinder oxygen. The standard models AirSep offers are the most efficientand reliable generators available today. With their proprietary mufflers, these units
also achieve the lowest sound levels in the industry.

AS-J, and AS-K
Generators
Note: The 220 V ~ ±10%, 50 Hz configurations for AS-D+ – AS-L		 are available for medical applications for export only outside		 of the USA.

Fully automatic, the generators require no specialized operating personnel. Simply
connect an air compressor or central air supply to the generator and your applicationor oxygen distribution system to the generator’s oxygen receiver. Then connect thepower cord to a grounded electrical outlet, turn the unit on, and set your oxygen
delivery pressure. That’s all there is to it. A simple on-off switch supplies oxygen
whenever you need it.

AirSep PSA Control Systems

AirSep Standard Generator models AS-D+ through AS-P may be equipped with an optional NEMA 4 touchscreen control panel with anintegrated oxygen monitor. Standard equipment on models AS-Q to AS-Z, the touchscreen provides a normal start-up system, monitors/controls the operation of the process valves, monitors signals coming from the pressure transducers, and provides an alarm system, as
well as a fail-safe shutdown mode. This control panel also features diagnostic capabilities and Ethernet access for remote monitoring ofprocess parameters. The various color screens are easy to follow, as the user-friendly interface maintains a consistent template design.

Packaged Systems

These skid-mounted or containerized, turnkey
packaged oxygen systems are ideal for locations
where a compressed air supply is limited orunavailable. Customers without adequate space or
those desiring ease of installation or portability, alsofind these options attractive. Containerized units
used for military applications are built to ISO 1-C
construction standards. All AirSep Standard Oxygen
Generators can be packaged using customerspecified or AirSep-recommended components.
Note: All configurations for medical gas are for export only outsideof the USA.

Medical Oxygen Systems

AirSep has over 4,500 hospital installations in50 countries worldwide. These plants operate
automatically to supply patient, surgical, andcritical care units in medical facilities, military
field hospitals, on-site emergency preparedness
centers, and disaster-relief efforts.
Note: All configurations for medical gas are for export only outsideof the USA.

Cylinder Refilling Systems

AirSep Oxygen Cylinder Refilling Plants enable customers to filloxygen cylinders for existing needs or to supply others. AirSep
manufacturers a complete line of turnkey oxygen cylinder refilling
plants — with capacities from 8-100s of cylinders per day.
Complete plants include a feed air compressor, refrigerated dryeror chiller, oxygen generator, oxygen compressor, and a cylinder
filling rack. The oxygen compressor delivers oxygen at up to
2,200 psig (15,169 kPa or 151.6 barg) to a high pressure manifold
capable of filling up to 10 cylinders at a time.
These cylinder refilling plants operate automatically andgenerate oxygen that meets the United States and European
Pharmacopoeia Oxygen 93 Percent (93% ±3%) Monograph. For
special applications, an optional high purity module may be added
to the plant, to increase oxygen concentration to 99% ±0.5%.
Note: All configurations for medical gas are for export only outside of the USA.
