A4571302515 Mercedes-Benz Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a vital engine-driven component within the air brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it generates a higher volume of compressed air compared to single-cylinder units, ensuring faster reservoir filling and consistent pressure for demanding braking requirements.

Compatibility and technical features

This unit is specifically designed for compatibility with Mercedes-Benz vehicles. It features a water-cooled configuration with a water inlet and outlet port size of M16x1,5, ensuring optimal thermal management during high-demand operation. The assembly includes an ESS feature and a water-cooled valve plate to maintain peak performance under heavy load.

Installation and maintenance guidance

For workshop technicians, ensuring proper installation is critical. This component features M26x1,5 air inlet and outlet ports, along with an M12x1,5 air unloader port. Given the Ø85.00 mm bore and 56 mm stroke, verify that all mounting interfaces and coolant lines align with the vehicle's original specifications to ensure seamless integration.

System performance and reliability

Maintaining steady air pressure is essential for the safety of heavy commercial fleets. Regular inspection of the through drive mechanism and cooling lines helps prevent system pressure drops in multi-axle tractor units or heavy-duty machinery.
