The Italo Ventania is the largest rotational fan in the Matthews Fan Company 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.
