301.03.0029 KNORR-BREMSE Compatible Air Dryer Valve

The heavy-duty grade complete air dryer valve is a critical component designed to ensure the stability and longevity of the pneumatic brake system. This part functions to remove moisture and contaminants from the compressed air stream, protecting downstream components from corrosion and ice formation. Engineered with high-strength components, it maintains consistent pressure performance within the braking circuit.

301.03.0029 is the OE-equivalent of the KNORR-BREMSE II30444, II30444N50, II30449, II30449AT, and LA 8235 air dryer valves used in heavy commercial vehicle brake systems. This unit is specifically designed to meet the rigorous requirements of the KNORR-BREMSE system architecture.

For workshop technicians, this assembly features precise port configurations including M22x1,5 and M12x1,5 connections to ensure a leak-free installation. Maintenance should involve regular checks of the air dryer cartridge and port integrity to ensure optimal pneumatic pressure of 10 BAR is maintained throughout the service cycle. Proper installation ensures the reliability of the heavy commercial vehicle's braking performance.
