What Is a Rotary Screw Compressor?

A rotary screw compressor features two meshed rotors that trap air between them and reduce its volume. This process generates compressed air for various industrial and manufacturing purposes. The machine contains two helical-shaped rotary screws, which are positive displacement mechanisms that produce compressed air in a continuous, sweeping motion.

Rotary screw compressors produce less pulsation than reciprocating/piston compressors and other versions. They provide massive volumes of compressed air and can function well in all types of weather conditions. These compressors also offer excellent energy efficiency and are easy to maintain.

What Is an Oil-Flooded Air Compressor?

Rotary screw air compressors can be oil-flooded or oil-free. An oil-flooded version uses oil to lubricate and seal the rotors on the air-end, enabling them to generate high pressure quickly and deliver compressed air in a single stage. The oil separates from the air before leaving the system. The air then recycles into the air-end for another use.

 

How Does an Oil-Flooded Air Compressor Work?

 

Oil-flooded air compressors use lubricating oil that enters the space between the two rotor screws, producing a hydraulic seal and transferring mechanical energy from the driving to the driven rotor. Air enters the air-end of the rotor from the suction side and moves through the vanes as the screws rotate. The rotors force oil and air through the air-end, causing the air to exit at the end of the screws. The air and oil then separate, and the air is cooled, filtered and routed back into the air-end.
