457 130 4515 SP2 Twin Cylinder Compressor for Mercedes-Benz

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical engine-driven unit within the air brake system of heavy commercial vehicles, generating the compressed air required for braking operations. By utilizing two piston-cylinder assemblies, this unit provides higher air output and faster reservoir filling compared to single-cylinder designs, making it ideal for high-demand applications.

Vehicle compatibility and technical features

This specific model is compatible with Mercedes-Benz trucks and other heavy commercial vehicles requiring reliable pneumatic pressure. It features a water-cooled design with a water inlet and outlet port size of M16x1,5, ensuring optimal thermal management during intensive operation. The unit includes an ESS feature and a water-cooled valve plate to maintain consistent performance under heavy loads.

Installation and maintenance guidance

For proper installation, technicians should verify the M26x1,5 air inlet and outlet ports and ensure the M12x1,5 unloader port is correctly configured. Given the 22.1 KG weight and specific mounting requirements, precise alignment with the engine drive is essential to prevent premature wear of the internal components.

Operational reliability

Maintaining correct coolant levels and checking for leaks at the M16x1,5 ports will help extend the service life of this compressor. Consult your authorized distributor to ensure correct fitment for your specific vehicle configuration.
