What is an Oil Lubricated Rotary Screw Compressor?
An oil-lubricated rotary screw compressor uses oil to seal, cool, and lubricate its internal components during compression. This design ensures efficient, continuous operation, making it ideal for industrial applications requiring high-duty performance.
A rotary screw air compressor uses twin spiral screws to compress air through positive displacement. In oil-lubricated systems, oil fills the space between the helical rotors, creating an air-tight hydraulic seal and efficiently transferring mechanical energy. As atmospheric air enters the system, the interlocking screws push it through the compression chamber. The oil also cools, seals, and lubricates the internal components, reducing friction and minimizing air leakage. This design allows for continuous, high-performance operation with steady air flow, making it ideal for demanding industrial applications. With lower maintenance requirements and an extended lifespan, these compressors deliver reliable and energy-efficient performance.

How Do Rotary Screw Air Compressors Work?
KLINA Oil-flooded rotary screw compressors operate by using two interlocking helical rotors that spin in opposite directions to compress air. As air enters the system, it fills the gap between the screw threads or grooves, where it is compressed as the screws rotate. The majority of rotary screw compressors are oil-flooded, where oil is used to seal, lubricate, and cool the compression process. However, oil-free screw compressors are also available for applications requiring contamination-free air.
- Air intake: Atmospheric air is drawn into the compressor through an intake valve.
- Rotor compression: Two interlocking helical rotors compress the air as they rotate.
- Oil injection: Oil is injected into the compression chamber, forming a seal and enhancing compression efficiency.
- Cooling: The oil absorbs heat generated during compression, cooling both the air and compressor components.
- Air-oil separation: After compression, the air-oil mixture is directed to an oil separator, where the oil is removed from the compressed air.
- Oil recirculation: The separated oil is recycled back into the system for reuse.
- Compressed air delivery: The purified, compressed air is then delivered to the air system for use.
