Viair 400P-Automatic Function Portable Compressor offers automatic function. The unit contains an onboard pressure switch that allows the unit to run until an internal pressure of 145 PSI is achieved at which point, the compressor will shut off. To start the compressor, attach to a tire valve stem and squeeze the trigger on the supplied gas station style inflation gun. Once air flows out of the unit, the compressor will restart. It can inflate up to a 35-inch tire from 0 to 30 PSI in less than 5 minutes. Air pressure can be monitored by releasing the trigger on the inflation gun, which will show current tire pressure.
