An average rotary screw air compressor has two interlocking helical rotors contained in a housing. Air comes in through a valve, typically known as the inlet valve and is definitely taken into the space between the rotors. As the screws convert, they reduce the volume of the air, therefore increasing the pressure.
The Screw Air Compressor china center of an air compressor is the screw element which can be called air-end. The air-end is certainly the most important component 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 surroundings compressor.
A Rotary Screw Air flow Compressor is a compressor that runs on the rotary-type positive displacement system, called a rotary screw, air-end. … Rotary Screw Compressors also make use of two 
inter-twined helical designed screws, known as rotors, to compress the surroundings.
