Using 6 blades instead of 10, AirVolution™ fans from MacroAir work by generating a large column of air that gently flows down to the ground and outward 360 degrees. The large, slow moving air mass moves throughout the space, mixing and circulating air more efficiently. The quiet operation of the AirVolution fan won’t create unnecessary noise or distraction and the gentle airflow won’t create or stir up dust. AirVolution is available in diameters from 8 to 24 feet.
