20842990 Volvo D9 Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor is engineered to meet the high air demand of heavy commercial vehicle braking systems through high-strength components. The unit features a water-cooled design to manage thermal loads during continuous operation, ensuring stable performance in demanding environments. With a 704cm³ swept volume and an Ø85.00 mm bore, it provides the necessary air volume for reliable pneumatic system pressure.

Compatible engines and vehicle fitment

This specific model is compatible with Volvo TAD1140-1172VE engines, specifically the D9 series. It is designed to integrate seamlessly into the engine's air supply architecture, matching the requirements of the vehicle's pneumatic systems through precise engineering of the mounting and port interfaces.

Installation and maintenance guidance

For proper installation, technicians should verify the water inlet and outlet ports (M16x1,5) and the air outlet (M26x1,5) against the existing system. Maintaining clean intake filters and ensuring adequate coolant flow through the water-cooled valve plate will extend the service life of this component. Consult your authorized distributor for installation guidance.

Replacement considerations

When replacing an existing unit, ensure that the drive type and cooling configuration match the original equipment specifications to prevent system mismatching.
