A4571303615 Mercedes-Benz Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical 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 rapid reservoir inflation and consistent pressure for braking operations. Built with high-strength components, it is designed to withstand the thermal and mechanical stresses of heavy-duty service.

Compatibility and technical specifications

This unit is specifically compatible with Mercedes-Benz vehicles. It features a water-cooled design with a water inlet and outlet port size of M16x1,5, alongside an air inlet/outlet port of M26x1,5 and an air unloader port of M12x1,5. The through drive configuration and ESS feature ensure seamless integration into existing pneumatic architectures.

Installation and maintenance guidance

For proper installation, technicians should verify the water cooling connections and ensure all ports are free of debris. The Ø85.00 mm cylinder diameter and 56 mm stroke must match the system requirements to maintain the specified 636cm³ swept volume. Regular inspection of the water jacket and unloader port is recommended to prevent pressure fluctuations.

System performance and troubleshooting

Maintaining consistent air output is vital for the safety of multi-axle tractor units and heavy trucks. If air pressure builds slowly or the unloader fails to function, consult your authorized distributor.
