A4571301815 Twin Cylinder Air Compressor for Mercedes-Benz

What does a twin cylinder compressor do?

This twin cylinder compressor is an essential component within the air brake system of heavy commercial vehicles, utilizing two piston-cylinder assemblies to generate the high-pressure air required for braking operations. By providing two compression strokes per revolution, it ensures efficient air reservoir filling and consistent pressure delivery even under heavy demand.

Vehicle compatibility and design

This specific unit is compatible with Mercedes-Benz vehicles. It is engineered with high-strength components to withstand the intense thermal and mechanical stresses found in heavy-duty engine environments. The design includes a water-cooled valve plate and integrated ESS features to maintain optimal operating temperatures and system stability.

Installation and maintenance

Installation and maintenance should be performed by a workshop technician to ensure correct alignment of the through-drive mechanism. The unit features an M26x1,5 air inlet and outlet port, along with M16x1,5 ports for water circulation.
