Vornado 533 Fan & Air Circulator in Black Unlike an ordinary fan, a Vornado air circulator doesn't just blow air. Instead, it produces true wholeroom 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 through out the room. Vornado air circulators conserve energy yearround by working with heating and cooling systems. With its classic elegant design, unique signature grill and deeppitched propeller, the 533 moves air up to 21 metres, while aerodynamically circulating all the air in a room. The 3speed control, located on the base, is easy to access and allows for speed selection to meet any circulation need. Its compact size makes it ideal for use in an office or small room. The patented removable grille makes cleaning easy and convenient.
