Power$ync® is a unique design that gives the compressor the ability to function as a base load machine AND a part-load machine. When you don’t need the entire capacity of the compressor, the Power$ync® quickly decreases the air flow output. The compressor is able to vary the output using specially designed lift valves (see photos above), controlled by the Power$ync® controller. These patented lift valves adjust automatically to match the demand of your application!
