Rated at an impressive 400 LPM free air delivery, this 4-cylinder powerhouse delivers outstanding real-world performance thanks to its high-flow 100 A power system and heavy-duty construction.
As pressure builds inside a tyre, airflow naturally decreases, but the ‘BIG V4’ keeps pumping hard. It inflates a 37" tyre from 9–38 PSI in just over 2 minutes 30 seconds, or two 37" tyres simultaneously in around 4 minutes, making it one of the fastest portable compressors on the market. In additional testing, the ‘BIG V4’ inflated a 215/60R16 tyre from 0 to 35 PSI in under 50 seconds, proof of its exceptional real-world performance.
Engineered for reliability and relentless performance, the ‘BIG V4’ is built for those who demand serious air and serious results. Whether you’re tackling remote tracks, towing heavy loads, or touring the outback, this compressor gets you aired up and back on the road fast.
Featuring an advanced pre-set pressure control system, operation is effortless: connect the power leads, attach the hoses, set your desired PSI, and let the compressor do the rest.
