A04571304815S Twin Cylinder Compressor for Mercedes-Benz

What does a twin cylinder compressor do?

This twin cylinder compressor is an engine-driven component designed to provide reliable compressed air for the pneumatic braking systems of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it generates a higher air output than single-cylinder alternatives, ensuring that air reservoirs are filled quickly even under high demand. This makes it an essential component for maintaining consistent pressure in demanding braking cycles.

Compatibility and technical specifications

This specific unit is compatible with Mercedes-Benz vehicles. It features a water-cooled design to manage thermal loads effectively during continuous operation. Technical specifications include a Ø85.00 cylinder bore, a 56 mm stroke, and a 636cm³ swept volume. The unit is equipped with M26x1,5 air inlet and outlet ports, alongside M16x1,5 water inlet and outlet ports to facilitate integration into the vehicle's existing cooling and pneumatic circuits.

Installation and maintenance guidance

For workshop technicians, verifying the mounting interface and port sizes is critical during installation. This compressor includes an ESS feature and a water-cooled valve plate to enhance durability under heavy-duty operating conditions. Ensure all connections are secure and the water cooling circuit is free of obstructions to maintain optimal performance and prevent overheating during long-haul operations.

Troubleshooting and selection

Regular inspection of the unloader port and cooling lines can help prevent system pressure fluctuations. When replacing an old unit, matching the specific port dimensions and cooling requirements ensures seamless integration into the heavy commercial vehicle's air system.
