Description
The high-strength components of this complete air dryer valve ensure consistent pneumatic stability within the braking system. Designed for heavy-duty commercial vehicle applications, this component plays a critical role in removing moisture and impurities from the compressed air stream to protect downstream pneumatic components.
301.03.0049 is the OE-equivalent of the KNORR-BREMSE II36258, II36258N00, II36258N50, and LA 8273 complete, air dryer valve used in KNORR-BREMSE systems. This part is engineered to meet strict technical standards for reliability in heavy commercial vehicle braking-suspension systems.
Workshop technicians should verify the port configurations—specifically the M22x1,5 connections at Port 1 and Port 21—before installation to ensure a perfect fit. Given the 24 V heater specification, this unit is optimized for modern heavy commercial vehicle electrical architectures. Regular inspection of the air dryer assembly is recommended to maintain optimal pressure levels and prevent moisture-related system failures.
Maintenance of the pneumatic circuit requires precision; ensure that all connections are seated correctly to maintain the 12,5 BAR operational pressure threshold.
