At the core of an oil free screw compressor is a rotary screw mechanism that compresses air using two helical rotors. Unlike standard lubricated compressors, an oil free rotary screw air compressor eliminates oil in the compression chamber altogether. This is achieved through advanced engineering, precision manufacturing, and the integration of alternative cooling methods such as water injected systems.

In the world of HVAC systems and industrial applications, the choice between scroll compressors and screw compressors is a key decision that affects energy efficiency, quiet operation, and overall system performance. Both technologies have unique strengths, and selecting the right one requires an understanding of how each functions, the operating conditions, and specific project requirements.

A rotary screw air compressor is a type of screw air compressor that uses two meshing helical screws—referred to as rotors—to compress air. These compressors are designed for continuous operation and are ideal for applications with a wide range of air demand.
