1100 010 021 MERCEDES BENZ Twin Cylinder, Air Compressor

This heavy-duty grade Twin Cylinder, Air Compressor is engineered to provide consistent air pressure for critical pneumatic systems in heavy commercial vehicles. Featuring a robust Ø85.00 cylinder bore and a 56 mm stroke, the component is designed to withstand high-stress operating environments while maintaining optimal swept volume for efficient air compression. The integrated water-cooling system ensures thermal stability during prolonged operation.

Specifically designed for compatibility with MERCEDES BENZ and WABCO systems, this part serves as an OE-equivalent for several high-demand applications. 1100 010 021 is the OE equivalent of the MERCEDES BENZ 457 130 20 15 SP1, 457 130 46 15 SP1, and 457 130 66 15 SP1 twin cylinder air compressors used in heavy commercial vehicle systems. It also matches the requirements for WABCO models including 911 553 003 0 SP1 and 911 553 007 0 SP1.

Workshop technicians should note that this unit is a water-cooled (W) configuration with specific port requirements: a Ø30 Air Inlet Port and M26x1,5 Air Outlet Port. The assembly includes an M16x1,5 water inlet and outlet setup to ensure effective temperature regulation. Regular maintenance of the cooling lines and checking the ESS feature functionality is recommended to ensure long-term system reliability and prevent pneumatic failures.
