911 504 504 0 WABCO Twin Cylinder, Air Compressor

The twin cylinder air compressor is a critical component designed to provide consistent pneumatic pressure within the heavy commercial vehicle air brake system. This unit is engineered with high-strength components to ensure reliable operation under demanding industrial conditions. Its robust construction supports the continuous demands of heavy-duty transport operations.

911 504 504 0 is the OE-equivalent of the WABCO Twin Cylinder, Air Compressor used in heavy-duty commercial vehicle systems. This part is fully compatible with WABCO systems and meets strict technical standards for performance and durability. The integration of the ESS feature and water-cooled valve plate ensures optimal thermal management during operation.

For workshop technicians, this compressor features an M26x1,5 air inlet and outlet port, along with an M12x1,5 unloader port for precise control. The water-cooled design (W) utilizes M14x1,5 inlet and outlet ports to maintain stable temperatures. Regular inspection of the through-drive mechanism and port connections is recommended during routine heavy commercial vehicle service intervals to ensure system-wide pneumatic integrity.
