Are you running a production where there should be no risk of oil contamination to the product? This is where the oil-free air compressor comes in. Also known as a dry screw compressor it ensures that the risk of contamination is eliminated.
Find out how the drying compressor achieves this below. We also have a range of oil-free air compressors available to suit your needs here. Check them out after you finish our guide on oil-free screw compressors.
The dry or "oil free" screw compressor compresses air without cooling the compression chamber. The compressor's operating temperature therefore rises to about 200°C, even at an operating pressure of 300 kPa.
For normal industrial air pressure (about 700 kPa), the drying compressor must therefore compress the air in two stages and cool the compressed air between the compression stage.
