An average rotary screw air flow compressor has two interlocking helical rotors contained in a housing. Air will come in through a valve, typically called the inlet valve and is definitely taken in to the space between the rotors. As the screws turn, they reduce the level of the air, hence increasing the pressure.
The cardiovascular of an air compressor is the 
screw element which can be called air-end. The Screw Air Compressor china air-end is certainly the most important component of any screw-type compressor. It’s that section of the machine where in fact the actual compression occurs. It is the heart of the rotary screw surroundings 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 formed screws, known as rotors, to compress the air.
