The 72" LIberator ceiling fan by TroposAir features nine blades that sweep away from the motor on a slight upward angle. This design helps the Liberator to spread airflow across an area unlike any other fan has the ability to achieve. The powerful DC motor is the largest of its kind, easily turning the big 72 inch blade span to keep any area feeling degrees cooler. It is an outdoor ceiling fan that has the UL damp location approval. Great for any large great room, and even better outside in hot humid environments to keep exterior entertainment spaces more comfortable than ever.
