21098915 Volvo FMX D11B Compressor

What does a single cylinder compressor do?

This single cylinder compressor serves as a critical component within the air brake system of heavy commercial vehicles. It utilizes a water-cooling mechanism to manage operational temperatures, ensuring consistent air production for braking and pneumatic systems. The unit is built with high-strength components to withstand the rigorous demands of heavy-duty engine cycles.

Vehicle and engine compatibility

This specific model is designed for fitment in Volvo FMX trucks equipped with D11B engines. It is an OE reference compatible part that maintains the required performance standards for the vehicle's pneumatic infrastructure. The design ensures seamless integration with existing engine mounting configurations.

Installation and maintenance guidance

For proper installation, technicians should verify the M26x1.5 air inlet and M22x1.5 air outlet port alignments. This water-cooled unit requires connection to the vehicle's cooling circuit via the M16x1.5 inlet and outlet ports to ensure optimal thermal regulation during operation.

Operational stability and selection

Maintaining correct coolant flow and checking port integrity is essential for preventing system pressure drops. This compressor is engineered to provide stable air supply under heavy load conditions common in construction and transport applications.
