For sale is a Quincy Duplex Compressor. It has two pumps model SLT-15. Each of these pumps is powered by a 7.5 HP Baldor three phase motor. However, according to Quincy, the pumps are capable of being driven twice faster by 15 HP motors. Presently, this compressor has a approximately 50 CFM capability, but if you upgraded the motors and motor controls, you could theoretically get approximately 100 CFM capability.
The pumps are general purpose pumps. The tank is 240 gallons. This compressor is huge! Pump: SLT-15, S/N G20238 Compressor: QC07524DX3, S/N 5019882, 240 gallon tank
The compressor was owned by Central DuPage Hospital. Then they upgraded it to something and donated it to Illinois Railroad museum. It stood there for a year and they decided that it was too big for them, at which point I bought it from them.
I checked this compressor out a little. The controls on it and the motors were wired for 460 volts. Since I only have 220 volts three phase at my house (from a phase converter), I had to disconnect the motors and rewire the motor connections for 230 volts three phase. I labeled the disconnected incoming wires 1, 2, 3 so that you can connect them back to the control box to get the right rotation. Both pumps run and pump air. The tank holds air.
I also cleaned up the minor rust spots
