What is a rotary screw air compressor?

Air compressors have been around for a long time now and serve the purpose of providing highly pressured air. They have several applications such as powering pneumatic devices and providing clean compressed air for gas cylinders and submerged surface-supplied divers.

There are four main types of air compressors in the market: Rotary Screw, Reciprocating Axial and Centrifugal. Each provide different levels of output and have different energy and maintenance needs, so you’ll need to choose wisely when looking for the right compressor for the job.

We’re going to focus on the most common type of air compressor: the rotary screw.


What is a rotary screw air compressor?

Rotary screw air compressors are positive displacement air compressors that generate energy from two internal rotors that turn in opposite directions. The air is then trapped between the two rotors and pressure is built up in the system.

Rotary screw compressors are built for continuous use and are relatively easy to maintain. As such, they are the most common types of air compressors that professionals and regular people turn to. They come in both portable and large units, and range in power from 5 horsepower up to 350 horsepower.
