Vornado creates whole room circulation using an airflow phenomenon called “Vortex Action.” An inlet guide cone directs air to the most efficient portion of the blades. In turn, the wide, heavily contoured blades churn the air into motion. The air then travels through a duct which sculpts the air into a column shape. As the air exits the circulator, Vornado’s AirTensity™ Grill straightens the airflow to ensure the air travels long distances.
