Terrafirma Twin On-Board Air Compressor 12v

Upgrade your 4x4 with the Terrafirma 12V Twin Motor Air Compressor — a powerful, quiet, and reliable on-board air system designed for serious off-road performance. Delivering fast, consistent air pressure for tyre inflation, winch free-spooling, and differential lock operation, this twin compressor can even run air tools when paired with a reservoir.

Built for rugged reliability, the Terrafirma twin compressor features high-quality, red anodised pump bodies that are both dust- and water-resistant. Producing up to 100 PSI, it includes an integrated safety valve and arrives pre-mounted on a sturdy, pre-drilled frame for easy installation. A heavy-duty wiring harness with a built-in on/off switch is supplied, and compatible air hoses and tyre inflators are available separately.

Engineered for long-term durability, the compressor uses hard-anodised cylinder bores and Teflon-impregnated carbon fibre piston seals to reduce friction and maximise service life. Each motor has individual in-line fuses for circuit protection, while an integrated pressure switch, relays, and brushless cooling fan maintain optimal temperature across the electronics and cylinder heads. The motors also feature internal thermal protection for safe operation in extreme conditions.

Whether you’re overlanding, off-roading, or running a workshop setup, the Terrafirma 12V Twin Motor Compressor is the ultimate solution for dependable on-board air power.
