- COMPRESSOR ASSEMBLY (12V)
- Voltage
- Outlet Port
- Safety Valve
- 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.
- 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.
