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