A4571306915 MERCEDES BENZ CONECTO O345 Twin Cylinder Air Compressor

This high-strength twin cylinder air compressor is a critical component for maintaining stable pneumatic pressure within the vehicle's braking and suspension systems. Designed with a robust architecture, it features a Ø85.00 mm bore and a 56 mm stroke to deliver a consistent 636cm³ swept volume. The integrated water-cooling system and water-cooled valve plate ensure the unit operates within optimal temperature ranges even under heavy-duty service conditions.

A4571306915 is the OE-equivalent air compressor used in the MERCEDES BENZ CONECTO O345. This unit is specifically engineered to match the technical requirements of high-capacity air systems, featuring M26x1,5 air inlet/outlet ports and an M12x1,5 unloader port. The assembly is designed for precision through-drive compatibility and includes the ESS feature for enhanced system stability.

For workshop technicians, the installation requires attention to the water inlet and outlet ports (M16x1,5) to ensure proper cooling flow. Regular inspection of the M26x1,5 pneumatic connections and ensuring the water-cooled valve plate remains free of debris is essential for maintaining long-term reliability in heavy commercial vehicle fleets. This part is engineered for direct fitment in professional workshop environments.

Technical specifications include a 23.2 KG weight and a dual-cylinder configuration to provide reliable air supply for braking systems. The component's design focuses on maintaining high pressure output while managing thermal loads effectively through its specialized water-cooling ports.
