Rotary Screw Compressors

Quincy Rotary Screw Compressors

The most popular source of compressed air for industrial applications, the rotary screw air compressor uses a simple compression concept. Air enters a sealed chamber where it is trapped between two contra-rotating rotors. As the rotors intermesh, they reduce the volume of trapped air and deliver it compressed to the proper pressure level.

With continuous contact cooling, rotary screw compressors can operate “fully loaded” 24/7 on a continuous duty cycle. A rotary screw compressor’s ability to operate for extended periods of time makes it ideal for demanding industrial applications.
