21379906 Twin Cylinder Compressor for Volvo Engines

What does a twin cylinder compressor do?

This twin cylinder compressor plays a critical role in the pneumatic system of heavy commercial vehicles by providing consistent air pressure for braking and auxiliary equipment. Built with high-strength components, this unit is engineered to withstand the intense thermal and mechanical stresses found in heavy-duty engine environments.

Vehicle and engine compatibility

This specific model is designed to fit Volvo TAD1341-1345VE engines featuring the D13 series. It operates as a water-cooled unit, ensuring optimal temperature regulation during continuous operation. The design includes an ESS feature and a water-cooled valve plate to maintain high efficiency throughout the service life.

Technical specifications and installation

Technicians should note the technical specifications during installation: the unit features a Ø85.00 mm cylinder bore, a 62 mm stroke, and an air inlet port of Ø35. The air outlet and water ports utilize M26x1,5 and M16x1,5 threading respectively. Proper torque application on the mounting flange is essential to prevent leaks in the pneumatic circuit.

Maintenance and selection guidance

When replacing an existing unit, it is vital to verify that the water cooling connections and port locations match the original installation to avoid system incompatibility.
