I86909000 KNORR-BREMSE Twin Cylinder, Air Compressor

The heavy-duty Twin Cylinder, Air Compressor is a critical component designed to ensure consistent air pressure within the braking system. This part utilizes high-strength components to maintain reliable operation under rigorous heavy commercial vehicle conditions. Its precise engineering ensures that the pneumatic systems of the vehicle remain functional and responsive throughout extended service intervals.

I86909000 is the OE-equivalent of the KNORR-BREMSE Twin Cylinder, Air Compressor used in heavy commercial vehicle systems. This specific unit features a cylinder bore of Ø75.00 and a stroke of 50 mm, providing a swept volume of 440cm³. It is engineered for compatibility with KNORR-BREMSE hardware to ensure seamless integration into existing pneumatic architectures.

For workshop technicians, the installation process requires attention to the water cooling ports, which utilize M16x1,5 threads for both inlet and outlet. The air inlet and outlet ports are specified at M26x1,5. Regular maintenance checks of the water cooling lines and ensuring the through-drive mechanism remains unobstructed is essential for maintaining optimal performance and preventing system overheating.

The unit is built with a robust water-cooled valve plate design to handle thermal loads effectively. Given its specialized construction, it is essential to verify that all connections match the specified port sizes before assembly to prevent leaks or pressure drops in the air brake system.
