VIAIR 440P Portable Air Compressor

Short Product Summary

The VIAIR 440P is the biggest portable compressor VIAIR makes, sized for 4x4s running large off-road tyres. It clamps straight onto your vehicle battery and brings aired-down tyres back up to road pressure quickly, with its own inflator/deflator and gauge.

Why This Product

Letting tyres down for sand, rocks or corrugations makes the going smoother and kinder to the vehicle, but every tyre has to be pumped up again before you're back on the tar. On big mud-terrain tyres that can mean a long wait next to each wheel. The 440P is made for that job, so airing up is a short stop rather than the end of your afternoon.

Key Features

• Top of VIAIR's portable range – VIAIR's biggest and strongest portable model, built for oversized tyres
• Quick fill on large tyres – VIAIR rates it to take a 37-inch tyre to 2 Bar from zero in under 5 minutes
• 5-in-1 inflator/deflator – add or let out air through one tool with a pressure gauge built in
• Heat-shielded air hose – the quick-connect hose has its own heat shield for long inflation sessions
• Thermal overload protection – adds a layer of safety when the compressor works hard
• Diamond-plate sand tray – a vibration-resistant base that stays steady on sand and uneven ground
• Dual battery clamps – power comes directly from the vehicle battery

Ideal For

• 4x4 owners on oversized tyres who air down often and want to get back to road pressure without a long wait
• Overlanders and touring rigs that need a strong compressor that packs away in a bag between trips
• Campers and caravanners who adjust tyre pressures on gravel roads and want one compressor for the job

Optional Fitment / Upgrade Notes

A few things to check before you buy:

• The 440P runs off dual battery clamps, so make sure you can reach your battery terminals easily
• VIAIR's fill time is based on a 37-inch tyre pumped up to 2 Bar from flat; your own time will depend on tyre size and starting pressure
• Tell us your tyre size and how you travel, and we'll confirm whether this portable unit or a vehicle-mounted VIAIR system is the better fit

FAQ

How fast does the VIAIR 440P fill a tyre?
VIAIR says it gets a 37-inch tyre to 2 Bar from zero in under 5 minutes. Smaller tyres or a higher starting pressure will change that time.

Does it come with a tyre gauge?
Yes. The 5-in-1 inflator/deflator has a pressure gauge built in, so you can check pressures while you add or release air.

How is it powered?
It connects directly to your vehicle's battery with dual battery clamps.

Is it only for big 4x4 tyres?
It's built with large off-road tyres in mind, and it also suits touring vehicles, campers and caravans.

How do I store it?
Everything packs into the dual-compartment carry bag, which keeps the compressor and its accessories organised between trips.
