VIAIR Steel Air Tank

Short Product Summary

The VIAIR Steel Air Tank range gives your 4x4 or vehicle a store of compressed air for onboard air systems, tyre inflation, air lockers and other pneumatic accessories. Built from cold-rolled steel with a powder-coated finish, it comes in three sizes and two pressure ratings to suit different onboard air setups.

Why This Product

A compressor alone can struggle to keep up when you need a burst of air quickly, whether that's locking a diff or topping up a tyre out on the trail. Adding a steel air tank to your onboard air system stores compressed air ready to use, so you're not waiting on the compressor to catch up every time you need it.

Key Features

• Cold-rolled steel construction – built for consistent weld quality and long-term reliability
• Black powder-coated finish – resists corrosion in outdoor and off-road conditions
• Pressure tested – VIAIR checks every tank under pressure for safe, reliable use
• 150 PSI or 200 PSI rating – choose the rating that matches your onboard air system
• Three size options – 0.5, 1.0 and 1.5 Gallon capacities to suit different installation spaces
• Wide operating temperature range – rated from -40°C to +80°C

Ideal For

• 4x4 owners building onboard air who want stored compressed air ready for tyre inflation or air lockers
• Overlanders with limited install space who can pick the 0.5 Gallon tank when room is tight and still have stored air on tap
• Anyone running pneumatic accessories who needs a steady reserve of compressed air on tap
