A4571303615 MERCEDES BENZ CONECTO O345 OM447 Air Compressor

This twin cylinder air compressor is engineered to provide consistent pneumatic pressure within the vehicle's air brake system. Designed for heavy-duty service, the component utilizes a water-cooled valve plate and a specialized internal structure to maintain high-strength performance under demanding operating conditions. The integration of the ESS feature ensures optimized air management and system stability during continuous operation.

A4571303615 is the OE-equivalent twin cylinder air compressor used in the MERCEDES BENZ CONECTO O345 with OM447 engine. This unit features a cylinder diameter of Ø85.00 mm and a stroke of 56 mm, with a total swept volume of 636cm³. The technical configuration includes an M26x1.5 air inlet and outlet, alongside an M12x1.5 unloader port, ensuring precise fitment within the original pneumatic architecture.

Workshop technicians can rely on the precise dimensions and robust build of this component during installation and routine maintenance. The water-cooled design (W) provides superior thermal management compared to standard air-cooled systems, which is essential for long-term durability in heavy commercial vehicle applications. Regular inspection of the M26x1.5 ports and the M16x1.5 water inlet/outlet connections is recommended to ensure optimal cooling efficiency and prevent system leaks.

For professional fleet maintenance, this part offers seamless compatibility with existing MERCEDES BENZ pneumatic systems. The through-drive design and high-grade materials ensure that the compressor maintains peak functionality even in high-stress environments, making it a reliable choice for keeping heavy vehicles on the road.
