A4571304815 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 replenishment. Built with high-strength components, it is designed to withstand the rigorous thermal and pressure demands of heavy-duty applications.

Compatibility and technical specifications

This specific unit is designed for compatibility with Mercedes-Benz vehicles. It features a water-cooled design with an M16x1,5 water inlet and outlet, an M26x1,5 air inlet/outlet, and an M12x1,5 unloader port. The configuration includes a 636cm³ swept volume and a through drive design to maintain consistent performance across various operating conditions.

Installation and maintenance guidance

For professional installation, technicians should verify the M26x1,5 thread sizes and ensure the water cooling lines are properly seated to prevent leaks. Regular inspection of the valve plate and unloader port is recommended to maintain optimal air output and prevent system pressure drops in the pneumatic circuit.

System performance and selection

When replacing this component, ensure the mounting interface matches the existing engine configuration to prevent vibration issues or misalignment.
