A4571304615 SP1 MERCEDES BENZ Twin Cylinder Air Compressor

The heavy-duty twin cylinder air compressor is a critical component for maintaining optimal pneumatic pressure within the braking system of heavy commercial vehicles. This unit features a robust construction designed to handle high-pressure demands while ensuring consistent air delivery through its dual-cylinder architecture and advanced water-cooling system.

A4571304615 SP1 is the OE-equivalent twin cylinder air compressor used in MERCEDES BENZ vehicles. This high-strength component provides reliable performance for heavy commercial vehicle applications, ensuring that the pneumatic systems receive stable air flow under demanding conditions. The assembly is engineered to meet exact technical specifications for seamless integration into the vehicle's air brake system.

For the workshop technician, this part features a Ø85.00 mm cylinder bore and a 56 mm stroke, optimizing the swept volume to 636cm³. The unit is water-cooled, utilizing M16x1,5 ports for both water inlet and outlet to manage thermal loads effectively. It also includes an ESS feature and a water-cooled valve plate to enhance durability during extended service intervals. Precise installation is required to ensure correct port alignment for the Ø30 air inlet and M26x1,5 outlet.

Regular maintenance checks of the water cooling lines and air unloader port (M12x1,5) are recommended to prevent system overheating or pressure fluctuations. Maintaining the integrity of the water cooling paths is essential for the long-term operation of this heavy-duty compressor.
