457 130 70 15 MERCEDES BENZ AXOR 2 OM457 Air Compressor

This high-strength twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the heavy commercial vehicle braking system. Designed with a dual-cylinder architecture, it features a Ø85.00 mm diameter and a 56 mm stroke to ensure optimal volumetric efficiency. The integration of a water-cooled valve plate and ESS feature ensures the component maintains stability under rigorous thermal loads during long-haul operations.

457 130 70 15 is the OE-equivalent twin cylinder air compressor used in the MERCEDES BENZ AXOR 2 OM457 engine series. This unit is specifically engineered to maintain the integrity of the pneumatic circuit, providing reliable airflow for both braking and suspension assistance. The part is designed to match the exact dimensional requirements of the original assembly to ensure seamless integration into the engine compartment.

For workshop technicians, this component features specialized port configurations including M26x1,5 for air inlet/outlet and M16x1,5 for water cooling ports. The water-cooled design (W) requires careful connection to ensure proper heat dissipation through the engine's cooling circuit. Regular inspection of the M12x1,5 air unloader port and checking for any leaks in the M26x1,5 connections is recommended during routine maintenance intervals to prevent pressure drops.

The robust construction of this twin cylinder unit ensures it can handle the high-pressure demands of heavy-duty transport environments without compromising performance. By maintaining precise tolerances in the displacement and porting, it serves as a critical component for the operational safety of the vehicle's pneumatic systems.
