Description

The high-strength component is designed to manage air quality and pressure within the braking system of heavy commercial vehicles. This complete air dryer valve assembly ensures the removal of moisture and contaminants from the pneumatic lines, maintaining optimal system pressure and preventing component corrosion during operation.

301.03.0046 is the OE-equivalent of the KNORR-BREMSE II35523 Complete, Air Dryer Valve used in MAN and NEOPLAN heavy vehicles. This unit is fully compatible with several high-specification systems including KNORR-BREMSE II35523, II35523N00, II35523N04, II35523N49, II35523N50, and LA 8270.

Workshop technicians should note the specific technical requirements for installation: the unit features a 24 V heater and specific port configurations including M22x1,5 (Port 1), M22x1,5 VOSS (Port 21), and M12x1,5 VOSS (Port 4/23). Proper mounting ensures the 10 BAR operating pressure is maintained without leakage.

Regular maintenance of the air dryer system is essential for long-term reliability in heavy commercial vehicle fleets. Ensuring that the ports are clean and the connections are secure helps prevent moisture ingress into the braking circuit.
