The Ar Ruthiane's unique hourglass support arms grasp bullet-shaped motor housings which rotate 360° 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. Matthews 360° rotational fans circulate heat and air conditioning more efficiently than traditional paddle fans. Constructed of cast aluminum, heavy spun and stamped steel, the Ar Ruthiane carries a limited lifetime warranty.
