The HTF type fire smoke exhaust axial fan is mainly used for quickly expelling smoke and toxic gases during a fire; the bidirectional axial fan can be used for ventilation and air exchange under normal circumstances and for smoke extraction during a fire.

The impeller is the core component responsible for air movement; the housing supports and protects internal parts; the motor provides power for the impeller’s rotation; the base secures the fan; and the wind cap, diffuser, and louvers optimize airflow and prevent rain and wind intrusion.

These fans are suitable for ventilation and air exchange in general factories, warehouses, offices, residential buildings, and can also be used in building air conditioning systems, ventilation duct systems, etc., to help regulate indoor air temperature, humidity, and air quality.

The working principle of anti-corrosion axial flow fans involves an electric motor driving the impeller to rotate within a cylindrical housing. Air enters through the collector, gains energy from the impeller, increasing pressure and velocity, and then discharges axially.
