Isis has been redesigned by Big Ass Fans to include 10 aerodynamic winglets, which minimize drag, increase airflow, and maximize efficiency. Weighing less than 100 pounds, Isis is 8' to 10' in diameter and is designed for commercial spaces. It can be installed in areas with ceilings as low as 12' and has a near-silent mover that operates at 40 dBA at maximum speed. In addition to its own efficient operation, Isis also aids in energy conservation by reducing the workload of heating and cooling systems, covering nine times the area of a 52" ceiling fan. It has a clear-anodized-aluminum finish with three standard colors: white, black, and chestnut. bigassfans.com/isis
