Induced draft fan is a device used for exhaust or ventilation, typically in industrial, commercial, or residential buildings. The working principle of a induced draft fan is to use mechanical or electric force to rotate blades or propellers to suck in and exhaust air from one place to another, in order to achieve the purpose of ventilation or exhaust.

Specifically, the working principle of the induced draft fan can be described as follows:
1. The induced draft fan is driven by an electric motor or other power source to rotate the blades or propeller.
2. The rotation of the fan blades or propellers generates airflow, which draws the surrounding air into the interior of the induced draft fan.
3. The inhaled air passes through the internal channels or pipes of the induced draft fan and is pushed to the area that requires ventilation or exhaust.
4. In the target area, the induced draft fan quickly exhausts the air, allowing the air in the area to circulate or renew, achieving the purpose of ventilation or exhaust.
The working principle of induced draft fan is based on the movement and flow of airflow, and with the help of mechanical equipment, it effectively achieves the functions of ventilation, air exchange, and exhaust.
