The 630B Vornado Air Circulator can move air up to 70 feet! Unlike a household fan, the Vornado air circulator uses signature energy efficient Vortex Technology to fully circulate all the air in the 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. Use the 630B all year long in the home or office for added comfort and energy savings in every season. The 630B has a three-speed control, fully directable airflow and a limited 5-year warranty - although our customers tell us their circulators far out last 5 years!
