Smoke and fire dampers and smoke exhaust fire dampers are critical components in building fire safety ventilation systems.
Smoke and fire dampers install in HVAC ducts, featuring manual/electric airflow adjustment. During fires, they automatically close at 70°C to block smoke and contain fire spread.
Smoke exhaust fire dampers operate in exhaust ducts, closing via fusible link activation at 280°C to prevent high-temperature smoke propagation, ensuring exhaust system integrity.
Both devices function with air and smoke media. Widely deployed in shopping malls, high-rises, and complexes, they integrate regulation and fire containment capabilities to enhance structural fire safety.
