The Vent-Bettina rotational ceiling fan is thoughtfully designed with its arms gently curving upwards. The fan offers fluid lines and quiet axial rotation. The motor 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 rotational is achieved by both motor head position and fan blade speed. Features
