An average rotary screw surroundings 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 turn, they reduce the level of the air, therefore increasing the pressure.
The heart of an air compressor is the screw element which is also called air-end. The air-end is the most important component of any screw-type compressor. It’s that portion of the machine where in fact the actual compression occurs. It is the heart of the rotary screw surroundings compressor.
A Rotary Screw Air Compressor is a compressor that runs on the rotary-type positive displacement mechanism, called a rotary screw, air-end. … Rotary Screw Compressors 
also use two inter-twined helical formed screws, known as rotors, to compress the atmosphere.
