A typical rotary screw air compressor has two interlocking helical rotors contained in a housing. Air will come in through a valve, typically known as the inlet valve and is taken into the space between your rotors. As the screws change, they reduce the volume of the air, therefore increasing the pressure.
The center of an air compressor may be the screw element which is also called air-end. The air-end is the most Screw Air Compressor china important part of any screw-type compressor. It’s that area of the machine where in fact the actual compression takes place. It is the cardiovascular of the rotary screw air flow compressor.
A Rotary Screw Atmosphere Compressor is a compressor that uses a rotary-type positive displacement mechanism, called 
a rotary screw, air-end. … Rotary Screw Compressors also make use of two inter-twined helical designed screws, referred to as rotors, to compress the air flow.
