The VIAIR 450P-RV portable compressor is perfect for inflating up to 42\" tires and other inflatable items. Its 1.80 CFM (100% duty cycle) compressor provides up to 150 psi capable of inflating even high pressure rated truck or RV tires. The 450P-RV 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 and effort to get tires inflated quickly.
