Understanding Screw Type Air Compressors: How They Work and Their Benefits

diesel air compressor

Screw type air compressors are widely used in various industries due to their efficiency and reliability. They work by compressing air using two interlocking helical rotors, which reduce the volume of air as it moves through the compressor. This results in an increase in air pressure that can be used for various applications.

How Screw Type Air Compressors Work

Screw type air compressors consist of two rotors that are interlocked and rotate in opposite directions. These rotors are housed in a casing with an inlet port that draws in air and an outlet port that releases compressed air.

As the rotors rotate, the air is drawn in through the inlet port and moves towards the discharge port. As the air moves through the compressor, the volume of the air is reduced, and the pressure increases. This is due to the interlocking helical rotors compressing the air and forcing it through the discharge port.

The Benefits of Screw Type Air Compressors

Screw type air compressors have several benefits over other types of compressors. These include:

1.Energy efficiency: Screw type air compressors are more energy-efficient than other types of compressors, such as reciprocating compressors. This is because they use less energy to produce the same amount of compressed air.

2.Reliability: Screw type air compressors are known for their reliability and can operate continuously for long periods without any issues. They are also less prone to breakdowns and require less maintenance compared to other types of compressors.

3.Low noise levels: Screw type air compressors produce less noise compared to other types of compressors, making them ideal for use in noise-sensitive environments.

4.High output capacity: Screw type air compressors can produce large volumes of compressed air, making them suitable for use in industries such as manufacturing, construction, and mining.


Screw type air compressors are an essential tool in various industries due to their efficiency, reliability, and high output capacity. Understanding how they work and their benefits can help you make an informed decision when choosing an air compressor for your application. Whether you’re in manufacturing, construction, or mining, a screw type air compressor could be the perfect solution for your compressed air needs.
