At the heart of all of SeQual’s oxygen products is the Advanced Technology Fractionator (ATF®) module, a patented device that economically separates oxygen from ambient air. The single integrated ATF® module eliminates approximately 200 connections, fittings and components found in most conventional oxygen concentrators and allows unsurpassed energy efficiency at low system weight.
