Description

The air dryer valve is a critical component in the pneumatic brake system of heavy commercial vehicles, ensuring moisture and contaminants are removed from the compressed air stream to maintain system reliability.

The VADEN ORIGINAL 301.02.0078 is the OE equivalent of the MAN 81521026118, 81521026120, 81521026122, 81521029120, SCANIA 390854, and WABCO 4324101140 components used in MAN and SCANIA vehicles. This part features a 24 V heater and specific VOSS port configurations (M22x1,5 and M16x1,5) to ensure precise pneumatic control under high-pressure conditions.

Maintenance technicians should regularly check the air dryer cartridge and port integrity to prevent moisture buildup in the braking system. This unit is engineered with high-strength components to withstand standard operating pressures of 8,5 BAR in demanding environments.

When replacing parts in the brake system, always verify the exact port dimensions and voltage requirements to ensure seamless integration with the existing pneumatic circuit.
