The Vent-Bettina rotational ceiling fan is thoughtfully designed with its arms gently upward curving. Offering fluid lines and quiet axial rotation, the motor 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.
