Like satellites orbiting a planet, the Brisas select mahogany blade head and lunar counterweight gently revolve 360 about its spherical gear housing. The fan head can be infinitely positioned in a 180-degree arc 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. Matthews 360 rotational fans circulate heat and air conditioning more efficiently than traditional paddle fans. Constructed of cast aluminum, heavy spun and stamped steel, the Brisa carries a limited lifetime warranty.
