A ceiling fan is a versatile and energy-efficient device installed on the ceiling to improve air circulation and maintain a comfortable indoor environment. It features rotating blades powered by an electric motor, which help cool down a room by creating a breeze or distribute warm air during winter when operated in reverse. Ceiling fans come in a variety of designs, sizes, and materials, ranging from traditional to modern styles, making them both a functional and decorative element. Many models include features like integrated lighting, remote controls, adjustable speeds, and smart home compatibility, enhancing their convenience and appeal. They are suitable for use in residential, commercial, and outdoor spaces.
