The definition of a vertical fan is a type of cooling system that consists of a fan that moves air vertically instead of horizontally. This type of fan typically has a base, usually cylindrical, which houses the fan blades, motor and control mechanism. The fan blades are usually orientated vertically, so they are able to move air up and down, instead of side to side. These vertical fans are typically used in commercial applications such as large enclosed spaces, industrial plants, and other industrial applications that require vertical air movement. They are also used in residential buildings, particularly in air conditioning systems. Vertical fans come in a variety of sizes and configurations and can be used to circulate air in large rooms or to provide airflow to a specific area. In some cases, the vertical fan is used to provide cooling to a specific area, such as the kitchen or a workstation. The vertical fan is a great choice for providing ventilation in buildings, as it is efficient, quiet, and can be easily installed
