Screw Air Compressors

A rotary screw air compressor is a type of air compressor which uses a rotary-type positive mechanism. Screw compressors can commonly be found where large, A rotary screw air compressor is a type of air compressor which uses a rotary-type positive mechanism. Screw compressors can commonly be found where large volumes of high-pressure air are in need. When your application requires continuous air demand, a screw compressor is the way to go, Working Principle of a Screw Compressor. The oil injected rotary screw compressor is a positive displacement type compressor. A given quantity of air or gas is trapped in a compression chamber and the space that it occupies is mechanically reduced, causing a corresponding rise in pressure prior to discharge, The main difference between a screw compressor and a piston (reciprocating) compressor is the way the air is compressed inside of the unit. Screw compressors use two meshing helical screws, while piston air compressors use pistons driven by a cranksh
