August 3, 2007 From palm leaf waving ancient Egyptians to the punkah fans of the Middle East and the first appearance of the electric desk fan in the late nineteenth century, the quest to keep cool has undergone steady improvements over time. The Vornado room air circulator is continuing this tradition with a design tailored to operate more effectively than a normal fan by circulating air around the whole room for constant air movement, rather than just blowing air in one direction. Though not an entirely new concept, the latest design achieves a tight vortex airflow that is drawn back around the perimeter of the room and recirculated to provide constant airflow and a more even temperature throughout the entire area. The AirTensity Grill acts as a flow-straightener and further assists in focusing the outward stream of air into a tight vortex airflow. This high velocity Vortex Beam of Air actually projects across the room pulling even more air into its beam. As the beam of air reaches the other side of the room, it is drawn back around the perimeter of the room and ultimately back to the circulator to be recharged again through this continuous cycle.
