Rotary Screw Compressors
Rotary
screw compressors operate on the principle of positive displacement, and use
rotating male and female rotors to compress ambient air. Oil injected into
the housing mixes with air to seal, lubricate, and cool the
components.
The oil is separated from the compresses air, cooled, filtered, and returned to
the injection point. The compressed air passes through an aftercooler to
reduce the temperature and
is then ready for air treatment equipment.
Rotary screw technology has become the standard for high quality, efficient compressed air in the automotive market... the major advantages of rotary screws over piston compressors include smooth, virtually vibration-free operation, and extremely low noise levels. Screw compressors operate at much cooler temperatures, often more than 200 degrees (F) cooler than the typical piston compressor. The completely balanced rotors combined with minimal moving parts allow Kaeser units to operate for more than 50,000 hours before requiring an overhaul. This is ten times as long as a typical piston compressor!
Kaeser's rotary screw compressors feature the proprietary Sigma Profile which produces more air per horsepower than other rotor designs. They also feature the patent pending Sigma control system that offers remote access capability, air demand tracking, operating hours and maintenance history.
