Like satellites orbiting a planet, the Brisa's select mahogany blade head and lunar counterweight gently revolve 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.Made with moisture and humidity-resistant materials suitable for covered outdoor spaces such as patios, porches, or sunroomsQuiet operation with a soothing white-noise effectAll Matthews Gerbar fans are hand made and not mass produced.Matthews rotational fans circulate heat and air conditioning more efficiently than traditional paddle fans.Constructed of cast aluminum, heavy spun and stamped steel, this fan carries a limited lifetime warranty.Each unique motor mount and fan head knob is made of genuine marbleized Bakelite.Standard Equipment: 10" Downrod.
