Fire-extraction smoke exhaust fans are mainly composed of: impeller, housing, inlet collector, guide vanes, motor, and other components. The impeller is made of a submergent and twisted flat plate, which is welded onto the hub. After undergoing dynamic balance testing and overspeed tests, it exhibits excellent aerodynamic performance. The fire-extraction smoke exhaust fan housing is cylindrical and forms an integrated unit with the sound-absorbing collector. The outlet is equipped with guide vanes, ensuring good airflow distribution and stable pressure. The fire-extraction smoke exhaust fan also features a secondary air intake, which is more conducive to reducing the environmental temperature of the motor.
Fire-extraction and smoke exhaust fans are widely used for ventilation and air exchange, as well as fire prevention and high-temperature smoke exhaust, in various locations such as underground tunnels, underground parking garages, civil buildings, metallurgy, and factories and mines.
Fire Extinguishing and Smoke Extraction Fan Features:
Excellent high-temperature performance: can operate continuously for 45 minutes at 300℃ and 20 hours per session at 100℃ without damage, widely used in high-grade civil construction, ovens, underground parking garages, tunnels, and other environments.
2. Wide Application Range: Can be adapted to the varying requirements of high-silk civil construction, utilizing variable or multi-speed drive forms to achieve the dual-purpose of a single machine.
3. High Efficiency: This series of fans utilizes advanced CAD system software, and is a newly developed product with a lightweight, multi-objective optimization design. The fan efficiency exceeds 80%, and it also features a stable efficiency curve, which is conducive to energy saving.
4. Easy installation, compact size: The fan is a basic axial flow fan type, which can be directly connected to the duct and mounted on the wall (installation can be vertical, horizontal, or suspended). Greatly saves the occupied floor area.
