A wall fan is a type of electric fan that is mounted on a wall. It is designed to be mounted directly on the wall and doesn't take up floor space like other fans. Wall fans typically have a strong and sturdy construction and are designed to provide a high level of air circulation in a room. They are commonly used in bedrooms, kitchens, living rooms, and other areas where space is limited. Some wall fans also come with adjustable speed settings and can be tilted to direct airflow in specific directions, making them a versatile cooling solution for homes and offices.
