The Ar Ruthiane's unique hourglass support arms grasp bullet-shaped motor housings that rotate about its teardrop center. The fan heads can be infinitely positioned in 180-degree arcs for optimum air movement; the greater the angles of the motors to the horizontal support rods (up or down), the faster the axial rotation. A slow, controlled axial rotation is achieved by both fan head position and fan blade speed.
LOVE IT!!! It is so unique. A real show stopper on my covered deck outside. Good quality item that was easy to install.. Cindy Barnett. Essex, ON. Sun Sep 30 2012
