When a twin-cylinder pump is not fast enough, a 400L/min tire inflator is the answer. This 4 cylinder air compressor runs four 50 mm bores on a direct-drive motor to deliver roughly double the airflow of a dual-cylinder unit, so even a big 4×4 or light-truck tyre comes back to pressure in minutes. It is a genuine heavy duty air compressor 12V owners ask for by class.

Rated to 150 PSI, this 150PSI tire inflator and quad cylinder air pump covers the pressures passenger, light-truck and RV tyres need. It is a battery clamp air compressor that draws from the vehicle battery through fused cables, and a digital tire inflator whose preset gauge stops the pump automatically at your target. The 50mm 4 cylinder inflator head and cast body are built for repeat, high-volume use.

As a portable tire inflator it is also a general off-road air compressor and car air compressor: coil hose, quick-coupler and adapters handle tyres, bike tubes and inflatables. The model is the WM102-45 tire inflator, a 4-cylinder platform that suits off-road, fleet and RV buyers — and a high-margin line for wholesale.
