412 704 012 0 WABCO Twin Cylinder, Air Compressor

The heavy-duty Twin Cylinder, Air Compressor is a critical component within the pneumatic braking system of heavy commercial vehicles. Designed to provide consistent air pressure, this part ensures the reliability of the air brake system through high-strength components and a robust water-cooled architecture. Its precision engineering is essential for maintaining optimal pneumatic performance in demanding environments.

412 704 012 0 is the OE-equivalent of the WABCO 412 704 012 0 Twin Cylinder, Air Compressor used in heavy commercial vehicle systems. This part is engineered to be compatible with WABCO systems, ensuring seamless integration with existing braking hardware and meeting strict technical requirements for heavy-duty applications.

For workshop technicians, this air compressor features a dual-cylinder design with a Ø85.00 bore and a 62 mm stroke, providing a swept volume of 704cm³. The unit is water-cooled (W) and includes an M16x1,5 water inlet and outlet port to manage thermal loads effectively. The assembly includes an M26x1,5 air outlet port and an M16x1,5 air unloader port to ensure stable operation.

Maintenance of the air compressor involves regular checks of the water cooling lines and the integrity of the M35 inlet connections. Given its role in the air brake system, ensuring that the water-cooled valve plate remains unobstructed is vital for preventing overheating during long-haul operations.
