Two Cylinder Compressor With No Markings
I bought this compressor at an auction about fifteen years ago, mounted it on a 40 gallon tank, added a 1/2 HP 1725 RPM motor with about a 2.5 inch pulley. It will produce about 90 PSI with some waiting.
The motor will not start in cool/cold weather (it is too small). With this setup, the compressor RPM would be a little under 300 RPM. This was all fine for topping up tires, cleaning carburetors and such but now my son needs something for painting and some sandblasting and I am trying to figure out this machines capability assuming a properly sized motor and drive.
It would be good to know the make and model but, in particular, I would like to know what a reasonable compressor speed might be and what the output might be.
The compressor has no identification except for "94535" stamped on the boss located just above the crankcase drain plug and an arrow on the pulley indicating clockwise rotation looking at the pulley end.
I started to disassemble the compressor in order to measure bore and stroke. The head came off easily but the cylinder block is being a bit contrary mostly because beating on these things makes me nervous.
The brass intake and discharge fittings were attached when I bought the unit.
