How to select
If consumers need no more than 0.3 MPa, a low-pressure compressor uses much less energy than a 0.7–0.8 MPa machine with a pressure reducer.
Questions and answers
Can the compressor replace a blower?
Yes, for pneumatic conveying and aeration up to 0.3 MPa a low-pressure screw compressor often replaces blowers.
Are 0.5 MPa models available?
Yes, there is a two-stage low-pressure series for 0.5 MPa.
