INFO on older CURTIS COMPRESSOR?? , Setup

[skylonda]

I am setting up a 3PH/ 5HP Curtis Compressor and wanted some advice on the Control and unloader setup. The Tank is Marked CURTIS (made 1974) , there are no markings on the pump except " 230". Was being used in an upholstery shop. It appears to be single stage, the motor is a 5PH Westinghouse. I ordered a new Furnas Pressure switch with an unloader connection (69HAU1). Should that tank fitting below the pressure switch be a check Valve? Will inspect tank prior to use. I am wondering if any maintenance would be available for this unit (if it can be identified)? Anyone know what the pump make and model are? Thanks in advance.

that's 3-phase, 5HP.

Pump looks like an older Quincy with two unloader towers.

Pump is a Quincy 230.....
Guessing they discontinued this model but there are models above and below this one, so they likely use the same pump or very similar. Pump is a top end model. I would check that tank very very carefully and hydro it, tank is 42 years old.
