An electrically operated roof extractor fan is a powerful ventilation system designed to expel hot, stale, or humid air from a building through the roof. Powered by an electric motor, it drives a fan that circulates air, creating a pressure difference that forces air out, ensuring continuous airflow. These fans are particularly effective in spaces like attics, warehouses, or industrial environments, where heat and moisture accumulation can lead to discomfort or damage. With features like automatic temperature or humidity sensors, they operate only when necessary, offering energy-efficient performance. Built to withstand harsh weather conditions, they are durable and require minimal maintenance.
The working principle of an electrically operated roof extractor fan relies on the use of an electric motor to power the fan blades, which create airflow and pressure differences. When the fan is activated, the motor rotates the fan blades, drawing warm, stale, or humid air from inside the building and expelling it through the roof vent. This continuous extraction helps regulate temperature and humidity levels within the building. In many models, built-in thermostats or humidity sensors automatically trigger the fan to operate when the temperature or moisture levels exceed a set threshold. This ensures efficient ventilation by expelling hot or moist air, preventing buildup of heat and moisture, while maintaining a comfortable and healthy indoor environment.
