Frequently Asked Questions:

What Is A Rotary Screw Air Compressor?

The rotary screw air compressors are the type of gas compressor which utilizes helical screws to compress the gas. They are usually used in industrial applications, automotive shops, factories, dealer shops, or body shops.

They are also used on high-power air tools such as impact wrenches and jackhammers. Rotary screw air compressors are best for the applications that require a continuous air demand.

The rotary screw air compressor air flow rate is very great and a lot of them have low operational noise.

The rotary screw air compressors use two types of meshing helical screws which are generally known as rotors. These are:

  1. Dry Running Rotary Screw Compressor
  2. Oil Flooded Rotary Screw Compressor
Dry Running Rotary Screw Compressor:

The dry-running air compressor typically relies on the timing gear which ensures that the male and female rotors for continuously efficient performance. 

Oil Flooded Rotary Screw Compressor:

In an oil-flooded air compressor the lubricating oil bridges between its rotors which then transfers the mechanical energy between the rotors and also provides a hydraulic seal. 

Conclusion:

In the above, we have listed the top rotary screw air compressor.

But If you are still unsure which one to choose then you need to ask yourself some questions like Does the air compressor I am getting fall in my budget? Does the Cfm, Psi and Tank size meet my requirements? In which places will I be using it? By asking these simple question you will easily pick the compressor of your need.
