457 130 78 15 Mercedes Benz CITARO 2 Air Compressor

This twin cylinder air compressor serves as a critical component within the pneumatic braking system of heavy commercial vehicles. Engineered with a dual-cylinder architecture, it provides consistent air delivery to ensure reliable brake performance. The unit features a specialized water-cooling design to manage thermal loads during continuous operation, maintaining high-strength performance in demanding urban transport environments.

457 130 78 15 is the OE equivalent of the MERCEDES BENZ 457 130 78 15 air compressor used in the MERCEDES BENZ CITARO 2. This precision-engineered component features a Ø92 / Ø60 bore and stroke configuration, delivering a swept volume of 490cm³. The assembly is optimized for seamless integration with the vehicle's existing pneumatic infrastructure, ensuring high compatibility and long-term operational stability.

For workshop technicians, the installation requires attention to the water-cooling ports (M16x1,5) and the air inlet/outlet ports (M30x1,5 and M26x1,5). Regular inspections of the water-cooled valve plate and through-drive system are recommended to ensure optimal pressure regulation. Maintaining the integrity of the coolant flow is essential for preventing overheating during high-frequency braking cycles in transit operations.

Technical specifications include a weight of approximately 26.2 KG and an ESS feature compatibility. Proper maintenance of the air supply lines and ensuring no blockages in the water cooling ports will extend the service life of this essential pneumatic component.
