A typical rotary screw air flow compressor has two interlocking helical Screw Air Compressor china 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 switch, they reduce the level of the air, therefore 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 portion of the machine where the actual compression occurs. It is the center of the rotary screw air flow compressor.
A Rotary 
Screw Surroundings Compressor is a compressor that runs on the 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 air.
