Like satellites orbiting a planet, the Brisa's 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.
