Built for Off-Roaders, Tourers, and Adventurers

Whether you’re exploring the outback, tackling beach tracks, or touring remote highways, reliable air is essential. The BIG V4’s 4-cylinder oil-free design ensures smooth, maintenance-free performance, while its pre-set pressure control system makes tyre inflation effortless.
Simply set your desired PSI, connect your hoses, and let the compressor handle the rest, it automatically stops when your set pressure is reached.

From deflated 37” tyres to sports balls and camping gear, the BIG V4 has the muscle to get the job done, quickly, cleanly, and consistently.

Power That Performs

At the heart of the Sherpa 4x4 ‘BIG V4’ is a powerful 12V, 1200W motor, drawing up to 100 amps through heavy-duty 5AWG power cables. Connected via 120A Anderson-style plugs and protected by a 125A inline fuse, this system is built for serious current flow and reliable operation under load.

With a flow rate of 400LPM (14CFM), the BIG V4 maintains consistent, high airflow even under pressure, inflating a 37" tyre from 9 to 38 PSI in just over 2½ minutes or two 37" tyres in around 4 minutes.

With an operating range from -20°C to +50°C, robust internal wiring, precision-machined cylinders, and oversized cooling fans, this compressor is designed for long life and dependable service, trip after trip.

Itsthermal overload and over-pressure protection keep it safe under extended use, offering up to 3 hours of duty cycle at 40 PSI (temperature dependent).
