The VIAIR 440P Portable Air Compressor is the ultimate portable tyre inflation solution for serious 4x4 enthusiasts, overlanders, off-road adventurers, and touring vehicles running oversized tyres.

As the largest and most powerful portable compressor in the VIAIR range, the 440P is engineered to deliver exceptional airflow and rapid tyre inflation in demanding conditions. Capable of inflating a 37-inch tyre from 0 to 2 Bar in under 5 minutes, the 440P is built for vehicles that require maximum performance and reliability when venturing off the beaten track.

Whether you're airing up after tackling sand dunes, rocky trails, mud, or corrugated tracks, the VIAIR 440P provides the power needed to get you back on the road quickly and efficiently.

The system includes VIAIR's innovative 5-in-1 tyre inflator/deflator with an integrated pressure gauge, allowing you to accurately manage tyre pressures for changing terrain conditions. A quick-connect air hose with an integrated heat shield ensures safe operation during extended use, while thermal overload protection provides additional reliability in demanding environments.

Designed for harsh off-road conditions, the compressor is mounted on a vibration-resistant diamond-plate sand tray that improves stability on soft surfaces and uneven terrain. Dual battery clamps provide direct power connection for maximum performance, and the dual-compartment carry bag keeps everything organised and protected during transport.
