81521026070 Air Dryer Valve for MAN Trucks

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic brake system by removing moisture and contaminants from the compressed air supply. By preventing water accumulation, it protects downstream components from corrosion and freezing, ensuring consistent braking performance for heavy commercial vehicles.

Compatibility and fitment

This specific component is designed for MAN vehicles, providing reliable air filtration and moisture separation. It maintains the integrity of the pneumatic circuit, which is essential for the safety of heavy-duty operations. Consult your authorized distributor to confirm exact fitment for your specific chassis.

Technical specifications and installation

The unit is equipped with a 24 V heater to prevent ice formation during cold weather operations. Technical specifications include M22x1.5 and M12x1.5 port sizes, designed to withstand pressures up to 10 BAR. Regular inspection of these connections is recommended during routine maintenance to prevent air leaks.

Maintenance and reliability

Proper installation ensures that the air brake system operates at peak efficiency. Using high-strength components helps reduce the risk of system failure and minimizes long-term maintenance costs for fleet managers and workshop technicians.
