301.03.0112 Complete, Air Processing Unit — IVECO

The heavy-duty 301.03.0112 Complete, Air Processing Unit is engineered to provide reliable air management within the pneumatic brake system of heavy commercial vehicles. This component is designed with high-strength components to ensure consistent pressure regulation and system stability under demanding operational conditions.

This unit is the OE-equivalent of the IVECO 42536874 and KNORR-BREMSE K039120N03, K039120N50, and LA 8605 models used in heavy commercial vehicle brake systems. It is specifically developed to maintain compatibility with IVECO vehicle architectures and KNORR-BREMSE pneumatic hardware.

For workshop technicians, this unit features a 24 V heater and specific port configurations including Port 1 (M22x1,5) and Port 21 (M16x1,5). It is designed to operate at a standard pressure of 10,5 BAR. Regular inspection of the connections and ensuring the integrity of the pneumatic lines is recommended during routine service to maintain optimal system function.

Maintenance of the air processing unit is critical for the longevity of the entire braking system. Technicians should verify that all port seals are intact and that the 24 V electrical connection is secure to prevent pressure drops or system failures in heavy commercial vehicle fleets.
