VIAIR – 40045 400P-Automatic Function Portable Compressor , Silver

Product Description

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.

The unit comes with an automatic shutoff function that will power down the 400P when the compressor is turned on, but not actively filling tires – making it unnecessary to turn the unit off between tire fills. In addition, the included closed-ended tire inflation gun allows for on-the-fly tire pressure reading, without having to turn the unit off to check tire pressure.

About Compressor Duty Cycle
Compressor duty cycle refers to amount of time a compressor can be operated in a given time period, at 100 PSI and at a standard ambient temperature of 72°F. Duty Cycle is commonly expressed in percentile as: compressor on time (compressor on time + off time) %. As an example, a compressor that is rated for 25% duty cycle means that compressor can be operated at: 100 PSI @ 72°F for 10 minutes on and 30 minutes off. 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle.
