An average rotary screw air flow compressor has two interlocking helical Screw Air Compressor rotors within a housing. Air comes in through a valve, typically called the inlet valve and is taken into the space between your rotors. As the screws convert, they reduce the level of the air, therefore increasing the pressure.
The cardiovascular of an air compressor may be the screw element which is also 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 air flow compressor.
A Rotary Screw Surroundings 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 shaped screws, known as rotors, to compress the atmosphere.
