High-temperature fire exhaust fans are suitable for high-rise buildings, underground structures, tunnels, and oven ventilation or smoke exhaust. They can operate continuously for over 30 minutes at temperatures up to 280°C and remain undamaged after 20 hours of continuous operation at a medium temperature of 100°C, making them ideal essential fire safety equipment.

The performance of the exhaust fan, as listed in the performance table, is divided into five operating conditions based on airflow. The performance table should be used as a reference when selecting. The qualified products of the fan at the factory meet the rated airflow with an error in total pressure not exceeding ±5%. The performance selection table represents the performance under standard conditions, and the performance specified in technical documents or order requirements should be based on the standard conditions; it features high efficiency with a flat efficiency curve, which is beneficial for energy saving. This model employs direct drive transmission with an electric motor and can meet the requirements of single-speed drive for high-end residential buildings, ovens, underground parking garages, tunnels, and other applications.
