Used air compressor. Runs on 110 volt, 2 horsepower motor. 120 PSI Some lower end noise. The control switch works as it should, turning the compressor on and off according to the tank pressure. In order to stop the compressor automatically turning itself on with dropping air pressure, you have to unplug the machine. The on-off power switch no longer works. Motor is very good - runs very well. Tank also very good. Please email for address to see and hear compressor in operation. Gordon Head area. NEEDS TO GO - I NEED THE ROOM. Thanks
