What is a rotary screw air compressor?Let me tell you.

Ever wonder what the rotary screw air compressors is, or how it works, and if your business should be using one? Below is a guide to help you better understand how rotary screw air compressors work and their benefit.


How Rotary Screw Air Compressors Work

A rotary screw air-end or element has twin rotors, which includes male and female parts rotating in opposite directions. Air fills the space between the rotors and, as they rotate, the volume between them and the surrounding housing decreases, squeezing or compressing the air into a smaller space. The length, pitch of the screw, and the form of the discharge port collectively determine the pressure ratio. Beyond that, there are no valves, or other mechanical forces that can cause unbalance, which allows a screw compressor to operate at high speeds while combining a large flow rate with small exterior dimensions – it packs a good punch for its size.


Benefits of Rotary Screw Air Compressors

Rotary screw compressors typically are used for continuous, commercial and industrial applications. Here are some of the primary advantages of a rotary screw compressor:

1. Lower noise outputs to meet OSHA requirements

2. Significant reduction in weight, typically by 50 percent

3. Easier maintenance due to fewer wearing parts to maintain or replace

4. Shock-less, non-wearing compression technology

5. Simplified maintenance procedures

6. Extremely low oil-carryover (as little as 3 ppm)

7. Less overall oil consumption

8. Proven reliability in harsh environments

9. Smaller physical footprint, typically by 50 percent

10. No “unbalanced” forces, less vibration transfer

11. Less heat generation

12. Zero reduction in capacity over time
