This is a 30 gallon Westinghouse compressor set up for garage. It is a 1 HP heavy duty motor. It is wired for 220 single phase and has a square D switch set to come on at 90psi and shut off at 125psi. It is very quiet and would be used for compressor piping system. There are no gauges. I purchased it to run in shop but never installed it. Good shape and a work horse. There are no gauges. (You would put gauge on ripe distribution system)
