Scales PA Jim Osmun made a cold call on a company and asked how their compressors were operating and was told that they had a blue one that would not pump air.
They had a base mounted 325 and a F350. Jim asked for a wrench and removed the copper tube from the unloader and the compressor started to pump air. The owner was ecstatic and asked how Jim fixed it. Jim said that the diaphragm was leaking and needed to be replaced. Jim said he sent a diaphragm at no charge. This company has spent approximately $250,000 purchasing mainly rotary screws from Quincy Compressor .
