The manufacturer known for large-diameter commercial fans introduces the Isis to the high-end residential market. Handmade from aircraft-grade aluminum, the 8-foot-diameter fan uses a prime mover motor that revolves the blades slowly and quietly, the company says. Isis can be installed in spaces with ceilings as low as 12 feet and comes standard in an aluminum finish; chestnut, black, white, and silver also are available.
