Basic Things You Need To Know About Screw Air Compressor

Screw compressors are the workplace for most manufacturers around the world. If you see a large building and do something there, there's a good chance that a rotary screw compressor is powering the manufacturing process.

Industrial turn air converters have a 100% duty cycle. It can work 24/7 and it works better and lasts longer when used that way. 

Understanding Compressors

A typical screw compressor has two locked scroll rotors built into the housing. Air enters through a valve commonly referred to as an intake valve and is discharged into the space between the rotors. By turning the screw, you reduce the air volume and thereby increase the pressure.

There are also screw compressors with only one screw. However, they are not very popular when it comes to compressed air. You'll see a lot more of this in cooling applications.

An installation that includes the rotor and the housing in which they are located is called an "airside" or air blower. This is the terminology for all rotary compressors, whether rotary, screw, or vane compressors – the part that compresses air is called the air valve.

Screw compressors can be oil-filled or "oil-free". The oil-free ones are in quotes because oil-free compressors don't deliver oil-free air (the air around us is air).

In oil-lubricated screw compressors, the male rotor is driven by a motor, and the female rotor is driven by the male rotor, or indeed by a thin layer of oil in between.
