22040497 SP1 Volvo B11R D11K Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component in the pneumatic braking system of heavy commercial vehicles. By providing consistent air pressure, it ensures the reliability of the braking and auxiliary air functions. This unit is constructed with high-strength components to withstand the intense thermal and mechanical stresses found in heavy-duty engine environments.

Vehicle and engine compatibility

This specific model is designed for Volvo B11R vehicles utilizing D11K engines. It features a through-drive configuration and is specifically optimized for water-cooled operation to maintain optimal thermal stability during continuous operation. The unit includes an ESS feature and a water-cooled valve plate to enhance long-term durability under heavy load.

Installation and maintenance guidance

For correct installation, technicians should verify that the water inlet and outlet ports (M16x1,5) and the air outlet port (M26x1,5) match the existing vehicle configuration. It is essential to ensure the drive gear and mounting flange are perfectly aligned with the engine's specifications to prevent premature wear or system failure.

Operational performance

When performing maintenance, check the air inlet port (Ø35) for debris and ensure the unloader port (M16x1,5) is functioning correctly to maintain stable pressure regulation within the pneumatic circuit.
