A typical rotary screw air flow compressor has two interlocking helical rotors within a housing. Air comes in through a valve, typically 
known as the inlet valve and is usually taken into the space between your rotors. As the Screw Air Compressor china screws convert, they reduce the level of the air, thus increasing the pressure.
The center of an air compressor is 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 takes place. It is the cardiovascular of the rotary screw atmosphere compressor.
A Rotary Screw Atmosphere 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 formed screws, known as rotors, to compress the atmosphere.
