Portable Offroad Air Compressor for Truck & SUV

The VIAIR 400P (40043) 12 Volt Portable Air Compressor for Truck Tires offers unmatched convenience and reliability for any journey. Whether you’re driving a truck, SUV, RV, or motorcycle, this air compressor provides the peace of mind that you'll never be stranded due to a flat tire.

Weighing just 10.4 pounds and measuring 10.87 inches in length, the 400P is designed for portability and ease of storage. Its compact size allows you to easily stow it in your trunk or cargo box, ensuring that it’s always accessible when needed. The compressor comes with a durable canvas carrying case featuring a top handle, making it simple to carry and use wherever you are—be it at home, on a busy road, or in remote locations.

This versatile compressor is compatible with a wide range of vehicles, including trucks, SUVs, motorcycles, and side-by-sides. It can inflate a 35-inch tire from 15 to 30 PSI in just 2 minutes and 45 seconds, making it a powerful tool for getting you back on the road swiftly.

Using the 400P is straightforward—just attach the alligator clips to your vehicle’s battery terminals, start the engine, connect the air hose to your tire, and power on the unit with its simple On/Off switch. The built-in pressure gauge helps you monitor and achieve the desired pressure with ease.

Ideal for both daily commuters and off-road enthusiasts, the VIAIR 400P is praised for its robust performance and reliability. Off-roading often demands more power than cigarette lighter plugs can provide, so the 400P’s direct battery connection is preferred for its ability to handle the higher current draw of more powerful compressors. Although VIAIR does offer models that connect via cigarette lighter, battery clamps are recommended for serious off-road use.

The 400P is equipped with features that cater to high-performance needs, such as a maximum working pressure of 150 PSI and a duty cycle of 33%. It can inflate tires up to 35 inches in diameter from 0 to 30 PSI in under 5 minutes. The compressor’s design includes a low power draw and is powered by any 12-volt battery, making it reliable for use even when far from home.

Included in the package are a zippered soft carry case, an inflation hose with a 100 PSI gauge, a heavy-duty sand tray with vibration isolators, dual battery clamps, a 25-foot 5-in-1 inflator/deflator hose, and other essential accessories. The compressor’s specifications include a permanent magnetic motor, a maximum amp draw of 30 amps, and an ambient temperature range of -40°F to 158°F.

The VIAIR 400P's compact and durable design, coupled with its high performance, makes it an excellent choice for both casual and serious users. Its 33% duty cycle ensures it can handle extended use without overheating, with a free flow capacity of 2.3 CFM. With a maximum recommended tire size of 35 inches and an IP54 rating for dust and water resistance, this compressor is built to withstand tough conditions.

VIAIR Corporation, with over 25 years in the industry, provides high-quality portable air compressors and inflators known for their durability and performance. The 400P model is backed by a one-year limited warranty, covering defects in workmanship and materials. This makes it a reliable companion for all your tire inflation needs, no matter where your adventures take you.
