  2. VIAIR 400P-RV Automatic Portable Compressor Kit (12V, 33% Duty, 40 Min. @ 30 PSI) 40047

    VIAIR 400P-RV Automatic Portable Compressor Kit (12V, 33% Duty, 40 Min. @ 30 PSI) 40047

    $299.95

    Product Description:

    VIAIR's 400P-RV Automatic offers automatic shut-off in a larger portable compressor kit that can inflate 35-inch tires from 0 to 30 PSI in less than 5 minutes. While the unit is intended for RV use, it can be used for virtually any tire since it comes with more 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 Automatic does not work with Presta bicycle valves.

    • Automatic shutoff pressure of 150 psi means that you never have to worry about turning the system off at a determined pressure, although for prolonged periods of non-use, you should disable power in case of air leaks
    • All required basic fittings are included to install a fully functional onboard air system that includes an air hose dedicated to filling tires
    • Maximum amp draw at peak pressure is 26-Amp (12-Volt)

    Specifications:

    • 12-Volt
    • Permanent Magnetic Motor
    • Duty Cycle: 33% @ 100 PSI
    • Max. Working Pressure: 150 PSI
    • Max. Amp Draw: 30 Amps

Rural King is the place to shop for all of your air compressors and accessories. Air compressors create energy from pressurized air, and this air is used for a lot of different applications as the air is depressurized. Air compressors are used for many things, from airing up tires, to running air powered tools.

The most common type of air compressors are: gas or electric powered. Their power is measured by the HP (Horsepower), and the CFM which is the cubic feet of air per minute that the air compressor has. The size of the tank will tell you how much compressed air that is in reserve is available.

For example, the Ingersoll Rand Air Compressor 5hp 80gallon will let you do a lot more projects before running out of air, verses the Mat Industries Air Compressor 1 Hp 7 Gallon. The size you need depends on the size of the job you need to do.

If you are working where there is no electricity available you will need a gas or diesel powered air compressor. The gas and diesel powered compressors will require ventilation because of the exhaust gases and they are noisy.
