An average rotary screw surroundings compressor has two interlocking helical rotors contained in a housing. Air comes 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 the most important part of any screw-type compressor. It’s that part of the machine where in fact the actual compression occurs. It is the center of the rotary screw atmosphere compressor.
A Rotary Screw Atmosphere Compressor is a compressor that uses a Screw Air Compressor china rotary-type positive displacement mechanism, called 
a rotary screw, air-end. … Rotary Screw Compressors also use two inter-twined helical designed screws, known as rotors, to compress the air.
