911 553 003 0 WABCO Twin Cylinder, Air Compressor

The air brake system relies on high-quality components to ensure consistent pressure and operational safety. This twin cylinder air compressor is engineered to provide reliable pneumatic power for heavy-duty applications, featuring a robust water-cooling system and an optimized cylinder bore design to maintain performance under demanding conditions.

This product is the OE equivalent of the WABCO 9115530030 air compressor used in heavy commercial vehicle systems. It is specifically developed to be compatible with WABCO hardware. The 9115530030 model ensures seamless integration within the pneumatic braking architecture of the vehicle.

Technical specifications include a cylinder bore of Ø85.00 mm and a stroke of 56 mm, providing a swept volume of 636cm³. The unit features an air inlet port of Ø30 and an air unloader port of M12x1,5. The water cooling system utilizes M16x1,5 ports for both inlet and outlet to manage thermal loads effectively during operation.

Maintenance technicians should regularly inspect the water cooling lines and connection points to ensure the compressor operates within optimal temperature ranges. Check the integrity of the M26x1,5 air outlet port and the ESS feature functionality during routine service intervals to prevent system downtime.
