Eaton Compressor of Engelwood, Ohio, said its 5-30 horsepower variable speed rotary screw compressor cuts energy consumption by up to 30 percent, compared to a centrifugal compressor.
The unit's speed is controlled by a variable-speed, alternating-current drive, which ensures that the motor does not operate at unnecessarily higher speeds.
Eaton Compressor is also known as Polar Air.
