25 SCFH oxygen production at 35 PSI is produced by an ATF-25 oxygen concentrator module.



ATF Oxygen Modules incorporate proven pressure swing adsorption (PSA) principles into a unique patented design, which allows these systems to be compact, efficient, rugged, and lower in cost. ATF modules offer unparalleled design flexibility and enable applications where on-site/on-board oxygen generation was previously impractical. 

A patented single rotary distribution valve built into the ATF module continually rotates at low speed by a small motor. The valve is maintenance-free, self-cleaning, insensitive to contamination, and invulnerable to wear. It directs the flow of compressed air to a group of four sieve beds (adsorption), while another four beds are purged into the atmosphere through 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 amplitutde pressure swings generated by the twelve sieve beds eliminate loud noise pulses, eliminate the need for a pressure regulator, and reduce compressor wear.
