A4571302415SP2 Twin Cylinder Compressor for Mercedes-Benz

What does a twin cylinder compressor do?

This twin cylinder compressor is a critical engine-driven component within the air brake system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, it delivers a higher air output compared to single-cylinder units, ensuring faster reservoir filling and consistent pressure for braking operations. This unit is engineered with high-strength components to withstand the rigorous thermal and mechanical stresses of heavy-duty service.

Compatibility and technical features

Designed specifically for compatibility with Mercedes-Benz vehicles, this component ensures precise integration into the pneumatic system. The unit features a water-cooled design with M16x1,5 inlet and outlet ports to manage operating temperatures effectively. It is also equipped with an ESS feature and a water-cooled valve plate to maintain optimal performance during continuous operation.

Installation and maintenance guidance

Installation and maintenance should be performed by a workshop technician to ensure correct mounting and connection of the M26x1,5 air ports. Regular checks of the water cooling lines and the M12x1,5 air unloader port are recommended to prevent system pressure fluctuations. Proper lubrication and seal integrity checks are vital for maintaining the high efficiency of the two-cylinder assembly.

Service and selection

For fleet managers and technicians, selecting a unit with the correct through drive configuration is essential for seamless engine integration. This compressor provides stable pneumatic delivery for high-demand applications such as tractor units and heavy trucks. Consult your authorized distributor.
