Description
The air dryer valve serves as a critical component in the pneumatic brake system, ensuring that moisture and contaminants are removed from the compressed air stream to maintain system integrity.
The 301.02.0077 is an OE equivalent of the MAN 81521026046, 81521026047, 81521026055, 81521026058, 81521026061, 81521026102, 81521026105, 81521026109, 81521026154, 81521026204, 81521026220, 81521026318 and WABCO 4324101120 models used in MAN and WABCO heavy commercial vehicle systems. This part provides essential filtration and pressure regulation for reliable performance.
Engineered with high-strength components, this unit features a 24 V heater and specific port configurations including M22x1,5 VOSS and M16x1,5 connections to meet exact technical requirements. It is designed to operate effectively at a pressure of 12,5 BAR to support heavy-duty braking cycles.
Maintenance technicians should regularly inspect the air dryer assembly to prevent moisture buildup in the braking system. Replacing the unit when symptoms of air leakage or pressure drops occur ensures continued safety for the vehicle's pneumatic operations. Consult your authorized distributor for further technical guidance.
