𝗘𝗟𝗘𝗖𝗧𝗥𝗜𝗖 𝗘𝗫𝗛𝗔𝗨𝗦𝗧 𝗙𝗔𝗡 An electric exhaust fan is a device used to remove stale air, moisture, and odors from an enclosed space such as a bathroom or kitchen. It works by using an electric motor to spin a fan blade, which pulls air out of the room and pushes it outside through a duct. Electric exhaust fans can be mounted on walls or ceilings and come in a range of sizes and styles to suit different applications. Some models also come with features such as timers, humidity sensors, and motion detectors to automatically turn the fan on and off as needed.
