Hello. I have a "never been used" johnson air compressor Model #152M , ser # SF-37. It is a aluminum housing diaphram type. My guess is that it is approx. 25-30 years old. I want to hook it up but need to know:
Max pressure, rpm, horsepower needed, and if and where spare parts are available.
Local air compressor repair places have never heard of this manufacturer.
I will be using this unit for a air supply for my airbrush painting, filling tires, etc.
Thank you for any help.
