Abstract: A dual function device which provides compressed air for tire inflation and a vacuum machine for cleaning operations at a single location. The air compressor and the vacuum machine are interconnected electrically so that a user may switch back and forth between each function as rapidly as may be required by the user without overloading or stalling the air compressor. A pressure relief valve is also provided in the air compressor outlet pipe to control the air pressure in the outlet pipe, thereby allowing restarts of the air compressor in an unloaded condition. In an alternate embodiment, the air compressor is connected to an air reservior. The timer controls the operation of a solenoid or a vacuum machine. The timer energizes the solenoid, which then opens to provide compressed air from the air reservoir.
