The 400H-Automatic Compressor (400H-A) is the newest addition to VIAIR’s H model family.
This compressor is IP54 Rated and CE certified.
With a duty cycle of 33%, this hard mount compressor is intended to fill tires up to 35” and can be operated for up to 40 minutes at a time before needing to be rested (at up to 40 PSI).
The 400H-A comes with a moisture resistant On/Off power switch and built-in automatic shut-off function.
The 400H-Automatic includes a 30ft inside braided coil hose, Gas Station-Style Tire Inflation Gun with 160 PSI Gauge, and a carry bag for convenience.
Compressors with automatic shutoff are useful when moving from tire to tire and when checking tire pressure during a tire fill.
H standard compressors must be turned off between tire fills and whenever you want to check tire pressure.
If you aren’t near the compressor, this can lead to running back and forth to turn the unit on and off.
Automatic compressors do not operate in this manner and will save time and effort to inflate tires quickly.
