20770303 SP1 Volvo Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical engine-driven component within the pneumatic system of heavy commercial vehicles. By utilizing two piston-cylinder assemblies, the unit provides higher air output and faster reservoir filling compared to single-cylinder alternatives, ensuring consistent pressure for braking and pneumatic auxiliary systems.

Compatibility and engine fitment

Specifically engineered for Volvo TAD1341-1345VE engines with the D13 series, this unit features a water-cooled design to manage thermal loads effectively during continuous operation. The assembly includes a water-cooled valve plate and is designed with an M26x1.5 air outlet port and an M16x1.5 air unloader port to ensure precise pneumatic control.

Technical specifications and installation

For optimal performance, technicians should verify that the mounting flange and drive gear configuration match the existing installation. This unit features a through-drive design and is compatible with specific cooling requirements via the M16x1.5 water inlet and outlet ports. Regular inspection of the air inlet port (Ø35) and unloader settings is recommended to maintain system integrity.

Maintenance and selection guidance
