The Acqua 360 rotational fan is thoughtfully designed to resemble the molecular structure of water, Earths most precious resource. The Acqua offers fluid lines and quiet axial rotation. Its 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. Matthews rotational fans circulate heat and air-conditioning more efficiently than traditional paddle fans. Constructed of cast aluminum and heavy stamped steel, the Acqua carries a limited lifetime warranty.
