Description
What does an air processing unit do?
This air processing unit serves as a critical component within the pneumatic brake system of heavy commercial vehicles. It integrates the vital functions of drying compressed air, regulating pressure, and distributing air to various circuits including braking and suspension. Constructed from high-strength components, it is engineered to withstand harsh operating environments while maintaining consistent air quality.System compatibility and specifications
This unit is compatible with WABCO systems and is designed to meet rigorous industry standards for reliability. It features a 24 V heater and specific pressure settings, including an opening pressure of 6.5 BAR for ports 21 and 22, and 7.2 BAR for ports 23 and 24, ensuring optimal performance across the vehicle's pneumatic network.Installation and maintenance guidance
For workshop technicians, proper installation involves verifying all port connections: Port 11 and 12 utilize M22x1,5 threads, while ports 4, 23, and 24 use M16x1,5 or M12x1,5 fittings. Regular inspection of the pressure sensor (5 V) and ensuring the closing pressure remains at approximately 4.5 BAR across the designated ports is essential for system health.System reliability and maintenance
Maintaining this unit prevents moisture buildup in the brake lines, which is vital for preventing component corrosion and ensuring reliable braking performance. Consult your authorized distributor to ensure correct fitment.OE cross-reference
