Product Q&A

Q:What is a fire/smoke exhaust damper?

A damper installed on smoke exhaust ducts that opens (automatically or manually) during a fire to vent smoke outdoors, protecting escape routes. It stays closed in normal operation to prevent cross-airflow.

Q:What's the difference between a smoke exhaust damper and a normal volume control damper?

Both. Most models offer electric + manual dual control: automatic opening on smoke detection, plus manual/remote and emergency manual operation during power failure.

Q:Is it manual or automatic?

Both. Most models offer electric + manual dual control: automatic opening on smoke detection, plus manual/remote and emergency manual operation during power failure.

Q:How does the fusible link work?

When ambient temperature reaches the set point (70 degrees Celsius), the link fuses and the damper opens automatically ----no power required

Q:What material is the damper made of?

Typically galvanized steel or stainless steel with a coated finish - high-temperature resistant and corrosion-proof for kitchen, humid and industrial use.
