I picked up this 1987 RamAir 80 galllon air compressor for next to nothing this morning. I was told it has some oil blow by in the lines and they decided to upgrade to a new system. I have not been able to find much information on this brand, other than another post on this website that hints that it might have a Campbell Haus pump. The thing I am confused about are the motor is directly connected to the pump, most compressors use a belt sytem. Is it worth trying to rebuild the pump if I can get the correct parts? Or am I better off converting it to a newer pump and motor?
