Fan technology refers to devices that create airflow by rotating blades, which can be used for cooling, ventilation, or air circulation. Fans come in various types, including ceiling fans, table fans, and exhaust fans, each designed for specific applications. They operate on the principle of moving air to enhance comfort and improve air quality in indoor spaces. Modern fan technology has evolved to include energy-efficient models that use less electricity while providing effective airflow. Some fans are equipped with features like smart controls, allowing users to adjust settings remotely or set timers. This innovation helps reduce energy consumption and enhances user convenience.
