ARB BRUSHED ON-BOARD TWIN AIR COMPRESSOR - 12 VOLT

Introduced in 2011, CKMTA12 was developed to deliver higher output, building on the success and trusted performance of the CKMA12 in both military and commercial markets. Permanently mounted, the range of ARB vehicle mounted compressors are water, dust, heat and shock resistant to withstand the rigours of off road travel. Each kit includes a full wiring harness with relay, multi position mounting bracket and pressure switch.

Providing optimum power, the ARB twin motor design delivers class-leading air flow for fast inflation purposes. Constructed of lightweight, high-strength engineering grade materials, it incorporates quality components for quiet operation and extended durability. The twin motors incorporate internal thermal protection against extreme temperature damage while a heavy duty in-line maxi fuse for each motor provides professional circuit protection. Available as a vehicle mounted kit with associated wiring loom and mounting hardware.

THE COMPLETE SOLUTION
