Mattei fixed-speed compressors deliver over 15% energy savings thanks to the low rotational speed of Rotary Vane Technology, high volumetric efficiency, and the absence of roller or thrust bearings.

Unlike traditional screw compressors, Mattei’s rotary vane design eliminates thrust forces and removes the need for bearings that wear over time. Instead, oil-lubricated white-metal bushings allow the shaft to rotate on a thin lubricant film, so the shaft and blades experience virtually no wear, with typical lifespans exceeding 1,000,000 hours.
