The Italo Ventania is the largest 360 rotational fan in the Matthews Fan Co collection. Its vortex sculpted arms grasp also remarkable, side-mounted fan heads in gentle, equatorial rotation. The fan heads can be infinitely positioned in 180-degree arcs for optimum air movement; the greater the angle of the motor 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.
