1100 220 020 Twin Cylinder, Air Compressor — MERCEDES BENZ

This twin cylinder air compressor is engineered to provide consistent pneumatic pressure for heavy commercial vehicle braking systems. Designed with a water-cooled architecture, the unit ensures optimal thermal regulation during high-load cycles. The component features a robust construction with a cylinder bore of Ø85.00 mm and a stroke of 56 mm, delivering a total swept volume of 636cm³ to meet demanding industrial standards.

1100 220 020 is the OE equivalent of the MERCEDES BENZ 906 130 16 15 SP2 and WABCO 412 636 001 0 SP1 air compressors used in heavy-duty truck systems. This part is engineered for precise compatibility with specific Mercedes Benz and WABCO hardware architectures, maintaining seamless integration within the pneumatic circuit.

The assembly process requires attention to the water inlet (M14x1,5) and outlet (M16x1,5) ports to ensure effective cooling. Workshop technicians should verify the through-drive alignment and the integrity of the M26x1,5 air outlet port during installation. Regular inspection of the unloader port (M12x1,5) and the ESS feature functionality is recommended to maintain optimal system pressure and prevent service interruptions in heavy commercial vehicles.
