Marine Fire/Smoke Damper

A motor‑actuated fire and smoke damper for marine ventilation ducts that automatically closes when a fusible link melts on temperature rise, with provisions for monthly manual testing. As a Smoke Damper, it is normally installed in machinery, accommodation, cargo or technical ventilation ductwork. In that role, its primary purpose is to move air or isolate ventilation paths according to normal HVAC and fire-safety requirements. Axial, centrifugal and supply fans differ in pressure and airflow characteristics, while fire and smoke dampers add safety closure and position indication. Capacity: Various duct sizes. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
