Smoke exhaust fans are the core equipment in building fire safety ventilation systems. They are mainly used to quickly remove high-temperature and toxic smoke during a fire, ensuring clear evacuation routes, slowing the spread of flames, and providing a safer environment for firefighting operations. These fans must comply with GB/T 16806, GB 51251, or EN 12101-3 standards and be capable of continuous operation under 280°C / 300°C for 60 to 120 minutes.
