The double-headed rotational 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 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.Features:Made with moisture and humidity-resistant materials suitable for covered outdoor spaces such as patios, porches, or sunroomsQuiet operation with a soothing white-noise effectIncreasing angles of fan head to support poles increases speed of axial rotationOptimum fan head position is 60 degreesCompatible with slanted ceilings up to 30 degrees for flexible installation.
