ATF Series

PSA Oxygen Concentrator Module
ATF stands for Advanced Technology Fractionators®. These oxygen modules incorporate provenpressure swing adsorption (PSA) principles into a unique patented design. AirSep’s design allows
these systems to be compact, efficient, rugged, and lower in cost. The ATF module offers
unparalleled design flexibility and enables applications where on-site/on-board oxygen generation
was previously impractical.

Features

How it Works

A patented single rotary distribution valve built into the ATF module is continuously rotated at low speed by a small motor. The valve is maintenance-free, selfcleaning, insensitive to contamination, and invulnerable to wear. It sequentially directs the flow of compressed air to a group of four sieve beds (adsorption), whileat the same time another four beds are purged into the atmosphere though the valve (desorption). The remaining four of the twelve beds are interconnected
through the valve to equalize pressure as the sieve beds sequentially transition between adsorption and desorption. The small amplitude pressure swings
generated by the ATF’s twelve sieve beds eliminate loud noise pulses, eliminate the need for a pressure regulator, and reduce compressor wear.

Warranty: 1 Year Parts and Factory Labor** An unprotected or inadequately ventilated environment, or improper control power may cause damage to the oxygen generator not covered under warranty.
1The maximum compressor pressure is a characteristic of the compressor and is higher than the air input pressure specification for the ATF modules.
2The ATF-25 and ATF-32 will achieve the specified oxygen flow and pressure when supplied with the specified air flow and pressure. Larger compressors areavailable to achieve slightly higher oxygen pressures. This technical data is presented as a basis for ATF and compressor selection only.
Compressor performance is based upon nominal units tested with ATFs under lab conditions.
All performance ratings based on an ambient temperature up to 100°F (38°C), up to 1,000 feet elevation, and 80% relative humidity.
