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.Features Matthews rotational fans circulate heat and air conditioning more efficiently than traditional paddle fans. Constructed of cast aluminum, heavy spun and stamped steel, the Vent-Bettina carries a limited lifetime warranty. Each unique motor mount and fan head knob is made of genuine marbleized Bakelite.
