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.

A rotary screw compressor has two meshed rotors that trap and reduce the volume of air between them. This process produces compressed air for a variety of industrial and manufacturing applications. Two helical-shaped rotary screws, or positive displacement mechanisms, are used in the machine to continuously and sweepingly produce compressed air.

 In comparison to other types of compressors like piston and reciprocating, rotary screw compressors have less pulsation. They can operate effectively in any weather and offer enormous compressed air volumes. These compressors are also very easy to maintain and have excellent energy efficiency.

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.

Oil-flooded or oil-free rotary screw air compressors are both possible. The rotors on the air-end of an oil-flooded version are lubricated and sealed with oil, allowing them to quickly produce high pressure and deliver compressed air in a single step. Before it leaves the system, the oil separates from the air. After that, the air is recycled into the air-end for additional 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.

Lubricating oil is injected into the gap between the two rotor screws in oil-flooded air compressors, creating a hydraulic seal and transferring mechanical energy from the driving to the driven rotor. As the screws turn, air enters the rotor’s air-end from the suction side and passes through the vanes. The air exits at the end of the screws as a result of the rotors forcing oil and air through the air-end. Following the separation of the air and oil, the air is cooled, filtered, and returned to the air-end.
