An exhaust fan is a ventilation device used to remove stale air, odors, and moisture from enclosed spaces. It consists of a fan motor and blades enclosed in a housing that is typically installed in walls, ceilings, or windows. Exhaust fans play a crucial role in maintaining indoor air quality by expelling unwanted air and promoting fresh air circulation. They are commonly used in kitchens, bathrooms, laundry rooms, and other areas prone to humidity and odors.
