What Are Screw Compressors?

Rotary screw compressors, or screw compressors, pressurize Freon by trapping it between two interlaced counter-rotating spiral screws. The volume of the Freon is physically reduced as it is pushed down through the rotors.

How Do Rotary Screw Compressors Work?

A screw compressor is able to compress Freon with the use of dual helical screws, also known as rotors. The intake side of screw compressors allows Freon to enter where it is then compressed as the helical screws rotate and then exits beyond the meshing rotors. The process area is made up of an inter-lobe volume between the screws, which is wider on the intake side and becomes more narrow towards the exhaust port. This narrowing volume is what actively compresses the Freon before moving onto the discharge manifold.

Benefits of Rotary
Screw Compressors


Continuous Flow & Pressurization

Screw compressors are made for continuous use and can be run with little to no downtime.

More Power

Since they have extremely high flow rates, screw compressors are quieter and more efficient than piston compressors.

Prolonged Lifespans

This type of compressor has a particularly long lifespan, making rotary screw compressors a great long-term investment.
