The double-headed rotational ceiling fan, Dagny, with cylindrical central housing and straight, parallel arms, is designed in the retrospective aesthetic. The Dagny offers fluid lines and quiet axial rotation. The motor 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 motor head position and fan blade speed. Matthews rotational fans circulate heat and air-conditioning more efficiently than traditional paddle fans.
