Workhorse oxygen concentrators simplify the process of oxygen system selection and setup. Simply plug the unit in and turn on for high concentrated oxygen delivered quietly and reliably. Each workhorse is the result of some state-of-the-art engineering that produced the Advanced Technology Fractionators (ATF). 

The necessary components have been meticulously matched to optimize performance. The Workhorse is intended to provide a turnkey solution when time or resources are not available to engineer a custom system. These PSA systems are economical and maintenance-free.

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 unparalled design flexibility and enable applications where on-site/on-board oxygen generation was previously impractical.

What is Pressure Swing Adsorption (PSA)

Clean, dry compressed air is fed into the first molecular sieve bed.  Nitrogen is adsorbed, while oxygen is allowed to flow through.  When the sieve in the first bed becomes full of nitrogen, the airflow is then directed into the second bed.  As the second bed separates the oxygen from the nitrogen, the first bed vents its nitrogen into the atmosphere.  Compressed air is once again fed into the first bed, and the process is repeated continuously.  A constant flow of oxygen is reliably produced.
