How a screw compressor works

A screw compressor works on the principle of rotary positive displacement compression. Inside the airend are two intermeshing rotors that turn in opposite directions. As air enters through the inlet valve, it is trapped in chambers between the rotors and housing. Rotor rotation gradually reduces chamber volume, increasing pressure and compressing the air.

Compression steps

Air intake
Air enters through the intake filter and inlet valve. The rotors trap air in chambers between the screws and the housing.
Compression
As the rotors turn, the trapped chamber volume decreases. This raises pressure, delivering smooth compression without pulsation.
Discharge and separation
When chamber pressure reaches discharge pressure, outlet opens. In oil-injected designs, oil is then separated and returned to the circuit.
Cooling and air treatment
Air is cooled in the aftercooler, condensate is removed, and drying/filtration can be added to reach required air quality.

TECHNOLOGY COMPARISON

Piston or screw compressors – how to choose?

Both compressed air technologies have their strengths. The right choice mainly depends on required airflow, operating regime, and pressure stability in your system.

Piston compressors

Suitable for occasional use
Lower initial investment
Higher pressure pulsation
Less efficient in continuous operation
Typical for workshops and smaller systems

Most often used in smaller workshops or applications where the compressor does not run continuously.

Screw compressors

Steady airflow without pulsation
High energy efficiency
Suitable for 24/7 operation
Stable system pressure
Ideal for industry and larger production lines

Thanks to stable operation and lower energy consumption, they are now the standard choice for industrial compressed air systems.

VSD speed control for compressors

On variable speed drive compressors (VSD), motor speed is not fixed but continuously adjusted to real compressed air demand. This means the compressor only produces as much air as needed at any given moment. As a result, unloaded running time is significantly reduced compared to fixed-speed compressors, where it is often a major source of unnecessary energy use.
