Air Compressor Overview of Design Features
Description:
The ARB CKMA12 and CKMA24 compressor kits were designed specifically as a versatile,
quick installing, compact yet high-flow air source to suit the ARB Air Locker, which also suits
the harsh and demanding environment of the ARB Air Locker user.
Features:
Available in 12V (CKMA12) or 24V (CKMA24) models.
Ultra compact design makes it the highest flowing compressor in its class (voltage vs. size),
and able to fit into tight areas where other high flowing compressors will not.
Fully sealed components for moisture and dust resistance.
Pressure switch controlled air manifold system specially designed to suit all ARB Air Locker
equipped vehicles.
Hard-anodized cylinder bore and PTFE (Teflon) impregnated carbon fibre piston seal for
reduced friction and maximum trouble free life.
Anodized mounting bracket dissipates motor heat and allows compressor to be
repositioned 180°.
Anti-vibration / sound deadening is integrated into the mount.
Relocatable splash resistant air filter assembly for cleaner, cooler air supply and versatile
waterproof air intake positioning.
High density and high flow washable sintered bronze air filter element.
Full wiring loom included for simplified installation and easy plug-in connectivity to Air
Locker control solenoids.
