Installing a fixed-speed MAXIMA as a base load machine and then trimming with an energy saving OPTIMA VSD compressor generates savings that are hard to beat.

Engineered like all Mattei's to operate at standard motor speeds, MAXIMA's massive airends turn at just 1,200 rpm versus our usual 1,800 rpm speeds. It is the incredible mechanical efficiency of Mattei airends that leverage this reduction in speed to deliver some of the lowest kW/100 CFM performance in the industry. In fact, the efficiency and output of single-stage MAXIMA rivals that of two-stage rotary screw type air compressors.
