Fully Automatic Smoke Exhaust Fire Damper
Our company’s fully automatic smoke‑exhaust fire damper is a core component of building smoke control and exhaust systems, integrating smoke extraction, fire protection, and automatic control in a single unit. Normally closed, it automatically opens during a fire to vent smoke and, when the temperature of the flue gas reaches 280°C, it closes automatically to prevent the spread of flames. This fully automatic fire‑protection valve combines smoke‑exhaust functionality with fire‑separation capabilities and is widely used in smoke‑exhaust ductwork for shopping malls, office buildings, underground parking garages, industrial plants, and other facilities.
