Viair 400P Portable Compressor is a larger portable compressor kit that can inflate up to a 35 inch tire from 0 to 30 PSI in less than 5 minutes by simply attaching its supplied heavy duty battery clamp power leads to the battery, attaching the lever style air chuck to a tire valve stem and turning the unit on.
Air pressure can be monitored using the 5-in-1 inline inflator/deflator hose and gauge included.
Always turn off the unit to take an accurate pressure reading since air flow into the tire will show an inaccurate pressure reading while the compressor is running.
Used and approved of by off road enthusiasts worldwide.
Let compressor cool off for about 30 minutes to allow thermal overload reset

VIAIR offers the most comprehensive line of fractional horsepower DC oil-less air compressors and air accessories for on-road, off-road, and industrial markets. Since 1998 our quality engineered compressors have become the industry standard for automotive aftermarket applications worldwide.
Heavy Duty Compressors for Tire Inflation
VIAIR’s heavy duty portable tire inflators can be used on any vehicle with a 12v battery source and are designed for tires ranging from 33″ to 42″ diameter.
These compressors are suitable for both on-road and off-road vehicles.
VIAIR’s Automatic Tire Inflatiors make tire filling simple! While most portable air compressors must be turned off between tire fills and checking tire pressure, the Automatic compressors only operate while the trigger on the inflation gun is pulled. This will certainly save you much needed time, making the overall process of filling your tires seem effortless.
For those in the off-road segment, airing down tires allows for better traction while off-roading. Once your tires need to get back to their normal pressures, you simply hook the compressor up to your battery, and fill them to the recommended on-road pressure your vehicle suggests.
For those in the on-road segment, proper tire inflation is very important because it helps keep your tires lasting longer, it’s better for gas mileage, and overall makes for a better ride while keeping you safe on the road.
