The double-headed 360 rotational fan, Dagny, with cylindrical central housing and straight, parallel arms, is designed in the retrospective aesthetic. The Dagny offers smooth 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 Dagny carries a limited lifetime warranty. The Dagny is also available with a light kit as the Dagny-LK.
