brunner air compressor

the unit likes like it the stationary 20 gallon is about 20-30 gallons with odd cast iron legs, supporting the unit. It then has a shelve on which a huge Brunner single cylinder sits that is turned by an electric motor , through the use of a belt (small wheel to large wheel on cyclinder). There is a what looks like a small glass gage on the cyclinder that measures the amount of oil in the cyclinder. Also on hop of the tank is a square box that appears to have the electrical cutoff switch? Coming out of the tank is a pipe with two pressure gages.

I tried to read the number of of the plate but they warned down best gues is 1352-250 or 1358-250 ...found model B in another spot.

info would be appreciated like spec... changing oil whta sae , how do you adjustment the pressure etc....

thanks

What you might want to do is drain the water from the tank.

Place the unit somewhere so that when the tank explodes from rust failure brought on by years of having some water in the tank, it doesn't cause bodily damage, or make some sort of situation worse by starting a fire or brakeing something.

If it runs and makes pressure, use it as intended.

If you need less pressure get a regulator.

If you want more pressure get another compressor.

Chances are the oil in the "pump" is just fine and would be just fine if left alone.
