911 504 505 0 WABCO Twin Cylinder, Air Compressor

This twin cylinder air compressor is engineered to provide reliable pneumatic-system pressure for heavy commercial vehicles. Designed for high-duty performance, it features a robust construction that ensures long-term durability within the engine and braking systems. The unit is specifically designed to handle demanding thermal loads through its water-cooling architecture.

911 504 505 0 is the OE-equivalent WABCO Twin Cylinder, Air Compressor used in WABCO systems. This high-strength component is fully compatible with WABCO (911 504 505 0) standards to maintain seamless integration with existing heavy-duty vehicle architectures. The part features a Ø75.00 cylinder bore and a 442cm³ swept volume to meet precise technical requirements.

Workshop technicians should ensure that the M26x1,5 air inlet and outlet ports are correctly aligned during installation. This water-cooled unit requires a stable coolant flow through the M14x1,5 ports to prevent overheating during extended operation. Regular inspections of the unloader port and the ESS feature integration are recommended to ensure consistent air pressure delivery and system safety.

Maintaining the cooling interface is critical for the longevity of the valve plate and cylinders. Proper torque application on the M26x1,5 connections will prevent air leakage and ensure the compressor operates within optimal thermal parameters under heavy-duty loads.
