Description, Q&A
Description. 400P-Automatic is VIAIR’s first Automatic shut-off function powerful portable tire inflator. This 33% duty cycle unit is capable of pressures up to 150 PSI and can be operated for up to 40 minutes at a time before needing to be rested (at up to 40 PSI). The 400P-Automatic comes with a close-ended gas station-style air gun for added convenience.
Portable compressors with automatic shutoff come into play when moving from tire to tire, and when checking tire pressure in the middle of a tire fill. A typical portable compressor must be turned off between tire fills, and anytime you want to check tire pressure. If you aren’t near the compressor, this can turn into running laps back and forth to the portable compressor to turn the unit on and off. Automatic portables do not work in this fashion and will save you time & effort to get tires inflated quickly.

Viair Heavy Duty Onboard Air System
This system has worked great for my F150 Raptor. It provided the base for an impressive custom modification. I can air up all four tires within minutes and provides enough air to power tools for off road requirements..

Air it up
Not only is the air system sleek. It gives your truck a feature that doesn't let you down, "air pressure" that is. Upgrade your truck.....upgrade your life.
