1100 020 021 MERCEDES BENZ (without gear) Twin Cylinder Air Compressor

This high-strength twin cylinder air compressor is engineered to provide reliable pneumatic pressure within the heavy commercial vehicle braking system. Designed with a robust structure, it ensures consistent performance under demanding operating conditions. The component features a dual-cylinder configuration with a specific swept volume of 636cm³ to maintain optimal system pressure.

The 1100 020 021 is the OE equivalent of the MERCEDES BENZ 4571302415SP2 and WABCO 4571304415SP2 used in MERCEDES BENZ vehicles. This specific model is also compatible with WABCO systems and meets the technical requirements for high-duty air brake applications. The part features an M26x1,5 air inlet and outlet port, along with a water-cooling system to ensure thermal stability during operation.

For workshop technicians, this unit includes an ESS feature and a water-cooled valve plate for enhanced durability. Maintenance should focus on checking the water inlet and outlet ports (M16x1,5) and ensuring the air unloader port (M12x1,5) remains free of debris to prevent system pressure fluctuations. Always verify the compatibility of the through-drive mechanism before installation to ensure a seamless fit within the engine compartment.
