The 630B Vornado Air Circulator can move air up to 70 feet. It doesn't just blow air. Instead, it literally bends and twists air to produce true whole-room air circulation using Vortex Action, exclusive to Vornado. Vornado air circulators save energy year-round by working with heating and cooling systems.

the fan is light weight and easy to set up. You can adjust the direction of air and it really works the part that distributes the incoming air. So for a rainy afternoon, open the window and set the fan next to it. I really cool up the air.
