Rotary screw compressors are a brilliant alternative to the common piston compressor, due to containing less moving parts they are easier to maintain and are designed to last for many years. They are also safe and extremely efficient, generating a low amount of heat and consuming less oil than other types of oil flooded air compressors, but not compromising on the performance. Many come with sound insulating options meaning that you get the power without the noise, which makes them ideal for small spaces or low noise applications.
