1321470 DAF CF75 ATI Twin Cylinder Air Compressor

The twin cylinder air compressor is a critical component within the pneumatic braking and control systems of heavy commercial vehicles. This specific unit provides consistent air-pressure generation through its dual-cylinder architecture, ensuring the reliability of the vehicle's pneumatic infrastructure. Designed with high-strength components, it is engineered to withstand the rigorous operating conditions found in heavy-duty transport applications.

1321470 is the OE-equivalent air compressor used in the DAF CF75 ATI. This unit features a dual-cylinder configuration with a 75.00 mm bore and a 50 mm stroke, resulting in a 440cm³ swept volume. The technical design includes M26x1,5 air inlet and outlet ports, alongside M16x1,5 water ports to facilitate efficient water cooling (W) for thermal regulation during continuous operation.

Workshop technicians should note that this component is specifically designed for water-cooled systems, requiring precise connection of the M16x1,5 water inlet and outlet ports to prevent overheating. The assembly includes a water-cooled valve plate and an optimized through-drive mechanism to ensure seamless integration with the engine's drive system. Regular inspection of the cooling lines and port seals is recommended during standard service intervals to maintain peak performance.

The unit's robust construction ensures that it meets the strict requirements of modern pneumatic systems. By maintaining the correct torque on the M26x1,5 connection points and ensuring efficient coolant flow through the designated ports, technicians can ensure long-term durability and prevent pressure fluctuations in the primary air system.
