Description
VIAIR 400P RV — overview
The VIAIR 400P RV is a 12V portable compressor intended for RV and motorhome tyre inflation. Its manufacturer-rated free airflow is 2.30 CFM at 0 PSI, with a maximum working pressure of 150 PSI. VIAIR lists it for tyres up to 35 inches; actual inflation times depend on tyre size, starting pressure, environmental conditions and the air hose arrangement.
The stated duty cycle is 33% at 100 PSI. This is a usage limit measured at the specified pressure, not a claim that the unit can operate continuously at every pressure. Allow cooling time and follow VIAIR’s user manual. The compressor is particularly useful for RV and motorhome tyre inflation, with the vehicle-specific hose and accessory arrangement described in the original kit contents. The RV configuration is designed around access to larger vehicle tyres; confirm that hose length and attachments in the supplied kit match your needs.

Our 400P-RV Automatic powerful portable tire inflator kit will inflate 275/80/22.5 tires from 80 to 90 psi in just 30 seconds. While the unit is intended for RV use, it can be used for virtually any tire since it comes with accessories for more varied inflating situations than any other portable compressor kit on the market today.
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-RV does not work with Presta bicycle valves, unless used with a Presta Valve Adapter.
