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