II39080F KNORR-BREMSE Twin Cylinder, Air Compressor

The II39080F twin cylinder air compressor is engineered to provide reliable air pressure for heavy commercial vehicle pneumatic systems. This component serves as a critical part of the engine's air production cycle, ensuring consistent performance under high-load conditions. Designed with a robust architecture, it features a water-cooling system to maintain optimal operating temperatures during continuous operation.

II39080F is the OE-equivalent of the KNORR-BREMSE II39080F Twin Cylinder, Air Compressor used in heavy commercial vehicle systems. This product is specifically engineered to meet the rigorous demands of professional workshop technicians and fleet managers who require precision-engineered components. The unit's design ensures seamless integration with existing braking and pneumatic hardware.

Technical specifications include a cylinder bore of Ø88.00 and a stroke of 50 mm, delivering a swept volume of 608cm³. The assembly features an air inlet port of Ø29 and an air outlet port of M26x1,5. For advanced thermal regulation, it utilizes a water inlet and outlet system (M16x1,5) and includes an ESS feature alongside a water-cooled valve plate to ensure long-term reliability in heavy-duty applications.

Maintenance of this air compressor requires careful attention to the water cooling lines and port connections to prevent leaks or overheating. Technicians should verify the integrity of the M22x1,5 air unloader port during every service interval to ensure the system maintains peak pneumatic efficiency.
