457 130 69 15 Mercedes-Benz CITARO 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, providing the necessary compressed air to meet high demand requirements. Built with heavy-duty grade materials, it ensures consistent pressure delivery to the pneumatic reservoirs, supporting the safety and reliability of the braking system in demanding operating conditions.

Compatible vehicles and engines

This specific unit is engineered for Mercedes-Benz CITARO (O 530) series, including variants such as the Citaro G, GN3, LÜ, N, and MUE, specifically when paired with OM 457 HLA engines. It is compatible with Mercedes-Benz systems and meets the strict performance standards required for urban and touring buses.

Installation and maintenance

Installation requires careful attention to the water cooling connections and port alignment. This model features an M26x1.5 air inlet and outlet port, along with M16x1.5 water inlet and outlet ports. For optimal service life, technicians should regularly inspect the water cooling circuit and ensure the air unloader port (M12x1.5) is free from debris.

Selection and fitment guidance

To ensure correct fitment, always verify that the through drive configuration and mounting interface match the existing unit on the engine. Maintaining clean intake filters and checking the air dryer system will help prevent premature wear of the internal piston assemblies.
