PSI has always been and will always be a full service compressor distributor. PSI has a long history of providing the best possible compressor service in the Midwest. With an average of 10 years experience in our service department, our technicians are quick to resolve customers problems. Our field engineers work through design and equipment selection, our installation team provides a turn-key solution, and our un-matched service department will handle the maintenance. As a result, PSI can offer our customers compressed air solutions rather than just equipment. Highly skilled system designers, welders and the latest equipment gives our installation team an advantage over traditional pipe fitters. Compressed air system piping is what we do everyday. Projects range from 1/2 Transair Systems to 10 Plant Headers.
