EVO1 Prevail 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
