The 450H-Automatic Compressor (450H-A) is VIAIR’s newest addition to our H model family. This compressor is CE certified and IP54 Rated. With 100% duty cycle, this hard mount compressor is intended to fill tires up to 37” and can be operated for up to an hour at a time before needing to be rested. The 450H-A comes with a built-in, moisture resistant On/Off power switch and automatic shut-off function. The 400H-Automatic comes with a 30ft inside braided coil hose, Gas Station-Style Tire Inflation Gun with 160 PSI Gauge and a carry bag for added convenience.
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. H standard compressors 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 compressor to turn the unit on and off. Automatic compressors do not work in this fashion and will save you time & effort to get tires inflated quickly.
