CKMTA12 & CKMTA24
Air Compressor Overview of Design Features
Description:
The ARB CKMTA12 and CKMTA24 twin on-board compressor kits were designed specifically as 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.
Features:
Available in 12V (CKMTA12) or 24V (CKMTA24) models.
Compact twin motor, dual cylinder design makes it the highest flowing compressor in its class
(voltage vs. size), at 174LPM [6.16CFM] meaning it is able to fit into tight areas where other high
flowing compressors will not.
Constructed entirely of light weight, high strength, engineering grade materials, including military
and aerospace standard components.
Pressure switch controlled air manifold system regulates pressure between 930kPa [135PSI] and
1030kPa[150PSI] suited to air tools and all ARB Air Locker equipped vehicles.
High efficiency design consumes only 56 Amps at maximum air flow.
Built with sealed components for moisture and dust resistance.
Hard-anodized cylinder bores and PTFE (Teflon) impregnated carbon fibre piston seals for reduced
friction and maximum trouble free life.
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 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.
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), 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 European made high shock rated cylindrical roller bearing.
Over-pressure safety valve equipped.
Fully serviceable and all replacement parts available.
EMF suppressed for use in proximity to sensitive electronic equipment. CE and C-Tick compliant.
Kit Includes:
Fully assembled and tested air compressor (12V or 24V).
Complete wiring loom w/ Air Locker solenoid plug-in contacts.
OEM quality IP54 rated compressor isolating dash switch.
2 x relocatable splash resistant air filter with washable high-flow sintered bronze filter cartridge.
Mounting bolts and washers.
Comprehensive photo illustrated installation guide.
