A typical rotary screw atmosphere compressor has two interlocking helical rotors contained in a housing. Air will come in through a valve, typically called the inlet valve and is certainly taken in to the space between the rotors. As the screws change, they reduce the volume of the air, hence increasing the pressure.
The cardiovascular 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 section 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 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 shaped screws, Screw Air Compressor china referred to as rotors, to compress the air flow.
