Les, my 110 volt air compressor is located in the generator sealed compartment, and is so quiet that you have to listen carefully to hear it running. Recently, I found it was running continuously, and discovered that the plastic hose that connects the tank to the compressor was broken. I cut it back about an inch, install a new farrell, and now everything is normal. If there are no leaks, I would suspect the pressure control switch may be cycling on and off with pressures set too close. Good luck.
