EVO2 Endure from FANAWAY® is an advanced ceiling fan with unique aesthetics and energy efficient design. Switched off,the traditionally intrusive fan blades automatically retract and conceal,and visually the unit transforms into a slim,modern light pendant. Turning the fan on creates a centrifugal force which deploys the blades to circulate air within a room. It creates open space in the room environment,accumulates less dust,and is unobtrusive and versatile to visually integrate into most building interiors. Please note- this fan with it's advanced blade technology does require that the blades be cleaned regularly. For optimal performance, we recommend you clean your Fanaway blades every season Click Here for installation instructions.
