Rotary Screw

The Rotary Screw Air Compressor has become a popular choice for providing compressed air in industrial applications.

A major reason is its simple compression concept: air enters a chamber and traps it between contra-rotating asymmetrical screws.

As these rotors inter-mesh, they reduce the volume of trapped air delivering it compressed to the proper pressure level.

Combined with continuous contact cooling, the rotary screw air compressor operates at lower temperatures. These temperatures reach approximately half of those produced by a typical reciprocating piston compressor.

The lower temperature allows the compressor to operate in a “fully loaded” continuous-duty cycle. It runs 24 hours a day, 365 days a year. Its ability to run for extended periods makes the rotary compressor ideal for demanding industrial applications.

Today, lubricant-injected Rotary Screw Air Compressors are used in most industrial plant air applications and for large applications in the service industries.

They offer several advantages over reciprocating compressors, including lower initial installation and maintenance costs, smaller size, reduced vibration and noise, reduced floor space requirements, and the option to install them on a level industrial plant floor.

Rotary screw compressors provide continuous flow and avoid the pressure pulsations typically found in reciprocating compressors. Two-stage rotary screw compressors generally operate more efficiently than single-stage ones
