Screw Compressors

Rotary screw compressors are the workhorse choice for any business that needs a steady, continuous supply of compressed air, running cooler and quieter than piston machines while delivering consistent air all day.

What is a rotary screw compressor?

A screw compressor uses two interlocking rotors to compress air smoothly and continuously, which makes it ideal for long duty cycles and high demand. Unlike piston machines, which are built for intermittent bursts, a screw compressor is happy running for hours at a time, so it suits busy workshops, manufacturing and industrial sites.

Fixed speed vs variable speed (VSD)

Fixed-speed machines run at full output whenever they are loaded, which is simple and cost-effective where air demand is fairly constant. Variable-speed (VSD) machines vary motor speed to match output to demand, and can significantly cut running costs where air use rises and falls through the day. If your demand varies, the energy saving often pays back the extra cost.

How to choose a screw compressor

The key figures are air delivery (CFM or l/min), working pressure (bar), motor size (kW) and whether a fixed or variable-speed machine suits your demand profile. For clean, stable air, pair the compressor with a dryer and an air receiver. Our team is happy to advise and arrange UK delivery.
