1100 020 021 MERCEDES BENZ Twin Cylinder, Air Compressor

This twin cylinder air compressor serves as a critical component within the pneumatic systems of heavy commercial vehicles, ensuring consistent air pressure for braking and auxiliary functions. Engineered with high-strength components, the unit features a robust water-cooling design to manage thermal loads during operation. The integration of a through-drive system and specific port dimensions ensures seamless mechanical synchronization within the engine compartment.

1100 020 021 is the OE equivalent of the MERCEDES BENZ 457.130.2415 SP2 and WABCO 457 130 4415 SP2 air compressors used in heavy-duty truck applications. This part is specifically engineered to match the technical requirements of MERCEDES BENZ systems, providing precise volumetric output and reliable pressure regulation. The dual-cylinder configuration supports high-demand cycles required in professional transport operations.

For workshop technicians, this component features an M26x1,5 air inlet and outlet port along with an M12x1,5 unloader port for precise control. The water cooling system utilizes M16x1,5 ports to maintain optimal operating temperatures. Maintenance should focus on checking the water cooling flow and ensuring all connections are secure to prevent pressure drops in the pneumatic circuit.

When performing a replacement, verify that the current system configuration matches the M26x1,5 threading specifications to ensure a leak-free installation. This unit is designed for heavy-duty service environments where consistent air production is vital for vehicle safety and braking performance.
