Port Damper Systems

Optimize your system's airflow for superior efficiency with SHB's advanced port dampers. Designed for either manual and automatic operation, our dampers allow you to precisely control airflow across all port levels—Primary, Secondary, Tertiary, and Quaternary.

Each damper blade is engineered to sit flush against the boiler, secured by a robust spring system. Collars placed along the link tube and torsion bar maintain the ideal pressure, ensuring a snug fit against the port castings. For added reliability, our port castings feature integrated guide rails that keep the damper blades perfectly aligned.

Custom-manufactured to match your port size and style, the SHB damper system seamlessly integrates with any boiler design, providing optimal performance and efficiency.
