A typical rotary screw air flow compressor has two interlocking Screw Air Compressor china helical rotors within a housing. Air will 
come in through a valve, typically called the inlet valve and can be taken in to the space between the rotors. As the screws convert, they reduce the volume of the air, hence increasing the pressure.
The heart of an air compressor may be the screw element which is also called air-end. The air-end is definitely the most important part of any screw-type compressor. It’s that area of the machine where the actual compression occurs. It is the center of the rotary screw atmosphere compressor.
A Rotary Screw Surroundings Compressor is a compressor that runs on the rotary-type positive displacement system, called a rotary screw, air-end. … Rotary Screw Compressors also use two inter-twined helical formed screws, referred to as rotors, to compress the atmosphere.
