With its unique signature grill and deep-pitched propeller, the 630 moves air up to 70 feet, while aerodynamically circulating all the air in a room. The 3-speed control allows for speed selection to meet any circulation need. The base of the 630 provides added stability when operated on a desktop or floor. Use a Vornado fan all year long for added comfort and energy savings in every season. Vornado Air Circulator Fan 630
