1100 020 021 Twin Cylinder Compressor

This engine-driven twin cylinder compressor is a critical component within the air brake system of heavy commercial vehicles, designed to generate high-volume compressed air through two piston-cylinder assemblies. By utilizing two compression strokes per crankshaft revolution, this unit delivers superior air output compared to single-cylinder alternatives, ensuring faster reservoir replenishment for demanding braking requirements.

The 1100 020 021 is the OE equivalent of the Mercedes-Benz 4571302415SP2 and WABCO 4571304415SP2 air compressors used in Mercedes-Benz vehicles. This specific model is engineered with a water-cooled design to maintain thermal stability during sustained high-demand operation, featuring an M26x1.5 air inlet/outlet and an M12x1.5 unloader port.

Designed for professional workshop technicians, this unit includes an ESS feature and a water-cooled valve plate to enhance durability under heavy-duty conditions. When replacing the unit, ensure the mounting interface and coolant connections match the existing installation to maintain system integrity.

The compressor's high-strength components are optimized for long-haul stability in tractor units and heavy vehicles. Check the compatibility list to ensure correct fitment for your specific engine configuration.
