21702066 Compatible Twin Cylinder Compressor

What does a twin cylinder compressor do?

This twin cylinder compressor serves as a critical component within the air brake system, providing the necessary pneumatic pressure required for heavy-duty braking and auxiliary air functions. Built with high-strength components, it is engineered to withstand the rigorous thermal and mechanical stresses found in heavy commercial vehicle engine environments.

Vehicle and engine compatibility

This specific model is designed to fit Volvo B13R trucks equipped with D13K engines. Its high-capacity architecture makes it an ideal replacement for systems requiring consistent, high-volume air output during long-haul operations. It ensures that the pneumatic system maintains optimal pressure levels even under extreme load conditions.

Technical specifications and cooling

The unit features a water-cooled design to manage operating temperatures effectively through the engine cooling circuit. Technical specifications include an air inlet port of M26x1,5, an air outlet port of M22x1,5, and specialized M18x1,5 ports for water circulation. The assembly includes a water-cooled valve plate and an integrated ESS feature for enhanced system reliability.

Installation and maintenance guidance

For optimal performance, technicians should verify all port connections and ensure the water cooling circuit is free of obstructions during installation. Maintaining correct clearance and checking the integrity of the M10x1 unloader port will help prevent premature wear in the pneumatic circuit.
