Unlike an ordinary fan, a Vornado air circulator doesn't just blow air. Instead, it produces true whole-room air circulation using Vortex Technology, exclusive to Vornado. So rather than being in the breeze or out of the breeze with an ordinary fan, you get an even temperature and circulation throughout the room. The Vornado 633 air circulator uses signature energy efficient Vortex Technology to move air up to 75 ft. while aerodynamically circulating all the air in a room, eliminating hot and cold spots. Ideal for small to mid-size rooms, such as a bedroom, kitchen or office. Operates at a whisper-quiet level. This air circulator can be placed on the floor or tabletop. The 633 has a three-speed control, fully detectable airflow and a limited 5-year warranty.
