II15993AT000 KNORR-BREMSE Twin Cylinder, Air Compressor

The technical efficiency of the air brake system relies heavily on the reliability of its compressor. This twin cylinder air compressor is engineered to provide consistent pneumatic pressure through a robust construction. With a cylinder bore of Ø75.00 mm and a stroke of 50 mm, it delivers a swept volume of 440cm³, making it an essential component for maintaining stable air supply in heavy commercial vehicles.

II15993AT000 is the OE-equivalent of the KNORR-BREMSE II15993AT000 Twin Cylinder, Air Compressor used in KNORR-BREMSE systems. This unit features a water-cooled design (W) with M16x1,5 inlet and outlet ports to manage thermal loads effectively. The integration of the ESS feature and a water-cooled valve plate ensures that the component operates within optimal temperature ranges during intensive duty cycles.

Workshop technicians should note the specific port dimensions for seamless installation: the air inlet and outlet ports are M26x1,5, while the air unloader port is M22x1,5. Given its weight of 19.3 KG and the through-drive configuration, precise mounting is required to ensure alignment with the engine drive. Regular inspection of the water cooling lines and port integrity is recommended to maintain peak system performance and prevent pressure drops.

This high-strength component is designed to meet the rigorous demands of heavy-duty transport environments. By maintaining strict tolerances in both the air and water port specifications, it ensures long-term compatibility with existing pneumatic architectures in heavy commercial vehicle fleets.
