457 130 78 15 MERCEDES BENZ Twin Cylinder Air Compressor

This heavy-duty twin cylinder air compressor plays a vital role in the pneumatic systems of heavy commercial vehicles, ensuring consistent air pressure for braking and auxiliary functions. Designed with a water-cooled valve plate and a robust two-cylinder architecture, this component is built to withstand high-stress operating conditions. The precise engineering of the cylinder bore and stroke ensures optimal volumetric efficiency for long-term service.

457 130 78 15 is the OE-equivalent air compressor used in the MERCEDES BENZ GRAN VIALE. This unit is engineered to meet strict technical specifications, providing a seamless fit within the vehicle's existing pneumatic infrastructure. It serves as a direct replacement for the original part, maintaining the system's integrity and performance levels without compromising on reliability.

For workshop technicians, installation requires attention to the water cooling ports (M16x1,5) and the air inlet/outlet connections to prevent leaks and ensure efficient thermal management. Given its water-cooled nature, proper connection to the cooling circuit is essential for preventing overheating during intensive operation. Regular inspections of the M30x1,5 inlet and M26x1,5 outlet ports are recommended during routine service intervals to ensure system longevity.

Maintaining a consistent air supply is critical for vehicle safety and operational uptime. This component is specifically designed for high-demand cycles found in long-haul transport applications, ensuring that the pneumatic system remains responsive under various load conditions.
