With the Vornado 683DC Energy Smart™ pedestal circulator, you experience powerful airflow (moves air up to 24m²), and up to 80% energy efficiency with its powerful DC motor. Its sturdy stand adjusts from 81.5cm – 96cm. An easy-use variable speed control dial gives you precise control of the signature “Vortex Action” that creates whole-room circulation, keeping the entire room cool and comfortable. The Vornado 683DC comes with a variable speed control knob to adjust airflow from whisper quiet to a powerful high setting for quick room circulation, multi-directional airflow and a 5-Year Replacement Warranty. Maintaining the 683DC is simple with a detachable grill that provides easy access to the blades for cleaning. Unlike typical fans, a 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 Air Circulator, Vornado’s AirTensity™ Grill straightens the airflow to ensure the air travels long distances. The airflow column will spin and twirl to the opposite corner hitting the wall where it will split off and recirculate to the centre of the room.
