A horizontal fan is a type of fan that is mounted horizontally on a wall or ceiling. It is typically used to provide ventilation in a room or to circulate air around a space. Unlike traditional fans, which are mounted vertically, horizontal fans are designed to move air in a horizontal direction, creating a more even distribution of air throughout the room. This type of fan is also more energy efficient than traditional fans, as it does not require as much energy to move the air. Additionally, horizontal fans are quieter than traditional fans, making them ideal for use in bedrooms and other quiet spaces. They also come in a variety of sizes and styles, making them a great choice for any room.
