Isis

The airfoils at the end of Isis’s 10 blades silently move large volumes of air in small spaces with ceilings as low as 12 feet.

Available with diameters of 8-12 feet, the fan weighs less than 100 pounds and consumes roughly as much energy as a refrigerator light bulb.

Thanks to its large wingspan, an 8-foot Isis fan can move more air than 9 standard 52-inch ceiling fans combined.
