Description
This high-strength component serves as a critical part within the pneumatic brake system, ensuring the efficient removal of moisture and contaminants from the compressed air stream. A reliable air dryer valve is essential for maintaining the integrity of the air supply and protecting downstream components from moisture damage in heavy commercial vehicle applications.
The 301.03.0029 is the OE equivalent of the KNORR-BREMSE II30444, II30444N50, II30449, II30449AT, and LA8235 parts used in KNORR-BREMSE systems. This part ensures seamless integration with high-pressure pneumatic networks where a 10 BAR operating pressure is required.
Technical specifications for this unit include specialized port configurations: Port 1 (M22x1,5), Port 21 (M22x1,5), Port 22 (M12x1,5), and Port 4/23 (M12x1,5). Workshop technicians should verify these thread sizes and pressure ratings during installation to ensure exact fitment and system safety.
Regular inspection of the air dryer assembly is recommended to prevent system failures caused by moisture accumulation or pressure drops. Maintaining these high-strength components helps ensure long-term reliability for heavy-duty braking performance.
