1100 020 020 Twin Cylinder, Air Compressor — MERCEDES BENZ

This high-strength component serves as a critical element in the pneumatic braking system of heavy commercial vehicles. As a twin cylinder air compressor, it is engineered to provide consistent air compression through its precise 636cm³ swept volume and specialized water-cooling architecture. The design incorporates a through-drive mechanism and features an ESS capability to ensure optimal operational stability under heavy-duty load conditions.

1100 020 020 is the OE equivalent of the MERCEDES BENZ A4571302415 SP1 and the WABCO 412 352 027 0 air compressor used in MERCEDES BENZ, KENWORTH, MERITOR, PACCAR, PETERBILT, and WABCO systems. This part ensures seamless integration with original equipment specifications to maintain the integrity of the vehicle's air brake systems.

For workshop technicians, this unit is designed for efficient assembly with specific port sizes including M26x1,5 for air inlet/outlet and M16x1,5 for water ports. Maintenance should focus on checking the water-cooling pathways and ensuring the M12x1,5 unloader port remains free of debris to prevent pressure fluctuations. Regular inspection of the water-cooled valve plate is recommended to ensure long-term reliability in the field.
