400P-Automatic is VIAIR’s first Automatic shut-off function portable
compressor. 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.
Please Note: The air hose supplied with this kit
may become brittle from prolonged exposure to UV/sunlight. – Stow when
not in use. Never allow the hose to come into contact with the head of
the compressor during use (melting hazard). The use of the included air
hose is not recommended in sub zero or freezing conditions. The 400P
does not work with Presta bicycle valves.
