II39080F KNORR-BREMSE Twin Cylinder, Air Compressor

The heavy-duty Twin Cylinder, Air Compressor is a critical component designed to maintain consistent pneumatic pressure within the braking system of heavy commercial vehicles. Engineered with a Ø88.00 cylinder bore and a 50 mm stroke, this unit provides a robust 608cm³ swept volume to ensure reliable air delivery. Its water-cooled design and integrated ESS feature provide superior thermal management, ensuring long-term durability under demanding operational conditions.

II39080F is the OE-equivalent of the KNORR-BREMSE II39080F Twin Cylinder, Air Compressor used in KNORR-BREMSE heavy commercial vehicle systems. This component is precision-engineered to meet strict technical requirements, featuring an air inlet port of Ø29 and an air outlet port of M26x1,5. The integration of the M22x1,5 air unloader port and M16x1,5 water ports ensures seamless assembly and compatibility with existing pneumatic architectures.

Workshop technicians can rely on the high-strength components of this compressor for efficient installation and maintenance. The unit is designed for water cooling (W) and features a through-drive mechanism to optimize power transmission. Regular inspection of the water inlet/outlet ports (M16x1,5) and the air unloader port is recommended to maintain optimal system pressure and prevent downtime in professional fleet services.
