1403939 DAF Single Cylinder, Air Compressor

This single cylinder air compressor is engineered to provide consistent pneumatic pressure within the vehicle's air brake system. Designed for durability in demanding environments, the component utilizes high-strength components to maintain structural integrity under operational stress. The unit is specifically optimized for heavy commercial vehicle applications where reliability is critical.

1403939 is the OE-equivalent of the DAF 1403939 single cylinder air compressor used in DAF heavy commercial vehicles. This precision-engineered part ensures seamless integration with the existing braking system architecture. It is designed to meet the rigorous demands of professional workshop technicians and fleet maintenance requirements.

The technical configuration includes a Ø80.00 cylinder bore with a 45 mm stroke and a 225cm³ swept volume. The assembly features an M26x1,5 air inlet port and an M18x1,5 air outlet port, utilizing a water-cooling (W) system with M16x1,5 inlet/outlet ports for optimal thermal management. Proper installation and regular inspection of the water-cooling connections and port seating are essential for long-term service life.

Maintenance of the air compressor system involves checking the through-drive connection and ensuring that the water-cooling ports remain free from debris to prevent overheating during long-haul operations.
