Screw compressors are a type of positive displacement compressor that use two interlocking screws to compress gas or air. They are widely used in various industrial applications due to their high efficiency, low noise levels, and compact size.

How does a screw compressor work?

Screw compressors work by using two rotors or screws that interlock with each other. As the rotors rotate, the gas or air is drawn into the space between the rotors and the compressor casing. As the rotors continue to rotate, the gas or air is compressed and then discharged through the outlet.

Advantages of screw compressors

Screw compressors offer a range of benefits, including high efficiency, low noise levels, and compact size. They are also easy to maintain and can operate continuously for long periods of time. Due to their design, they can provide a continuous flow of compressed air or gas, making them suitable for applications such as manufacturing and chemical plants.


Screw compressors are commonly used in various industrial applications, including food and beverage production, pharmaceutical manufacturing, and automotive manufacturing. They are also used in construction and mining applications, where portable units can be used for drilling and other activities. Additionally, they can be used for HVAC systems and refrigeration units.
