With clean, fluid lines, the Dagny LK rotational fan is a striking centerpiece in any space. Its movement about its cylindrical center housing is smooth and quiet. Dagny LKs dual fan heads can be infinitely positioned in 180-degree arcs for optimum and customized air movement. As the angle between the fan heads and the horizontal support rods is increased, so does the speed of Dagny LKs axial rotation. Matthews rotational fans circulate heat and air conditioning more efficiently than traditional paddle fans.
