A typical rotary screw atmosphere compressor has two interlocking helical rotors within a housing. Air comes 
in through a valve, typically called the inlet valve and can be taken in to the space between your rotors. As the screws change, they reduce the level of the air, therefore increasing the pressure.
The heart of an air compressor is the screw element which can be called air-end. The air-end is definitely the most important component of any screw-type compressor. It’s that area of the machine where in fact the actual compression occurs. It is the cardiovascular of the rotary screw atmosphere compressor.
A Rotary Screw Atmosphere Compressor is a compressor that uses a rotary-type positive displacement mechanism, called a rotary screw, air-end. … Rotary Screw Compressors also make use of two inter-twined helical Screw Air Compressor china shaped screws, known as rotors, to compress the surroundings.
