Frequently Asked Questions
+ What is the difference between the ARB CKMTA12 and CKMA12?
The CKMTA12 is the twin motor version with 72 LPM flow rate; the CKMA12 is the single motor version with 42 LPM. Both run at 100% duty cycle. The twin motor airs up a full-sized 4WD about 40% faster — from ~5–7 minutes per tyre to ~3–4 minutes. The twin motor costs ~$150 more. For solo tourers, the single motor is adequate. For groups or anyone who values speed, the twin motor is worth the premium.
+ Can I mount an ARB compressor under the bonnet?
Yes — both CKMTA12 and CKMA12 can be permanently mounted under the bonnet or in the engine bay as a fixed installation. This is a popular setup for serious 4WD tourers who want the compressor always available without unpacking it. ARB sells mounting kits for specific vehicles. Alternatively, both units come with an alligator clip cable for portable battery-direct use.
+ What is the ARB compressor warranty in Australia?
ARB compressors come with a 2-year warranty backed by ARB's extensive Australian dealer network. Parts and service are available at ARB stores in every major city and many regional centres. This makes ARB the most serviceable compressor brand for Australian touring.
+ How long does the ARB twin motor take to air up a 4WD?
The ARB CKMTA12 twin motor (72 LPM) airs up a typical 285/75R16 4WD tyre from 20 PSI to 35 PSI in approximately 3–4 minutes. For a full set of four tyres, expect 12–16 minutes total — including connecting and disconnecting the hose. The single motor CKMA12 (42 LPM) takes 5–7 minutes per tyre, or about 20–28 minutes for four tyres.
