An average rotary screw air compressor has two interlocking helical rotors contained in a housing. Air comes in through a valve, typically called the inlet valve and is taken in to the space between the rotors. As the screws turn, they reduce the volume of the air, thus increasing the pressure.

The cardiovascular 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 section of the machine where the actual compression occurs. It is the center of the rotary screw air compressor.

A Rotary Screw Air Compressor is a compressor that uses a rotary-type positive displacement mechanism, called a rotary screw, air-end. … Rotary Screw Compressors also use two inter-twined helical shaped screws, Screw Air Compressor china referred to as rotors, to compress the air.
