Description

The heavy-duty grade materials used in this component ensure reliable air filtration and moisture control within the pneumatic braking system. This complete assembly is engineered to maintain optimal pressure levels and protect downstream components from contaminants in heavy commercial vehicle environments.

301.03.0083 is the OE-equivalent of the KNORR-BREMSE Complete, Air Dryer Valve used in KNORR-BREMSE systems. This part is fully compatible with several high-specification references including I93079004, II33509004, II36007, II36007N50, II38715F004, K044410K50, LA 9004, and SEB01916004.

Designed for workshop technicians and fleet managers, this unit features a 24 V heater and specific port configurations such as M22x1,5 and M16x1,5 VOSS to ensure a precise fit during maintenance cycles. Regular inspection of the air dryer assembly is recommended to ensure system longevity and prevent pneumatic failures in heavy commercial vehicles.

When replacing an existing unit, verify that all port dimensions—specifically the M22x1,5 and M12x1,5 connections—match your current vehicle configuration to ensure seamless integration with the existing brake system architecture.
