Rotary Screw Air Compressor

Basics of the Rotary Screw Air Compressor

A rotary screw air compressor is a positive displacement compression system that includes a pair of matching helical screws (also referred to as “twin screw compressors”). They operate by trapping air between two meshed rotors and reducing the volume of that trapped air as it moves through the rotors. The compressed air created from the reduction in volume can be used in numerous applications. Screw Compressors are commonly used to replace piston compressors, in commercial and industrial applications, where large volumes of high-pressure air are needed.

Reciprocating air compressors, which is also known as piston compressors, physically push air into a small space, using pistons, and then collect that compressed air in an air receiver tank. Reciprocating air compressors have been around for decades and are relatively inexpensive. Rotary screw air compressors are an improved version of the reciprocating air compressor.

The rotary screw air compressors is more expensive than the traditional reciprocating model and has numerous benefits, which include:

  • Continuous Air Flow/100% duty cycle
  • Large quantities of air
  • Higher CFM (Cubic Feet per Minute) per HP (horsepower)
  • Longer lifespan
  • Better warranties
  • Quieter
  • Energy Efficient

A popular benefit of the rotary screw air compressor is that it can run continuously so there’s no need to wait for an air receiver tank to fill before you start using the air. Many people appreciate the longevity, reliability and easy access to instant air.
