ARB's new twin on-board compressor kits were designed to fill the market need for a compact sized yet high-volume compressed air source to suit the high volume airflow needs of most air powered tools, and also to suit the actuation and control needs of the ARB Air Locker, and the harsh and demanding environment of the ARB Air Locker user. Ducted IP55 sealed brushless DC cooling fan and anodized motor mounting brackets effectively dissipate heat from the motors, heads and electronics allowing for a 100% duty cycle (under room temperature conditions). Anti-vibration / sound deadening is integrated into the mount. Relocatable splash resistant air filter assemblies for cleaner, cooler air supply and versatile waterproof air intake positioning. Built with sealed components for moisture and dust resistance. High density and high flow washable sintered bronze air filter elements. Full wiring loom included for simplified installation and easy plug-in connectivity to Air Locker control solenoids. Equipped with dual heavy duty Maxi-Fuses for professional in-line circuit protection and true circuit redundancy in case of a fault. Motors are water sealed, 100% ball bearing equipped (i.e., no bushings used), and feature a unique linear brush pre-load system for extra long life, low heat and quiet operation throughout the life of the unit. Motors are internally thermal protected against extreme temperature damage. Compressor pistons are equipped with a heavy duty European made cylindrical roller bearing. Over-pressure safety valve equipped. Sealed illuminated automotive grade dash switch included. Fully serviceable and all replacement parts available. EMF suppressed for use in proximity to sensitive electronic equipment. CE and C-Tick compliant. Engineered, built, and individually dyno-tested in Australia from local and imported components.
