Few designs can match the timeless and sophisticated aesthetic of the Duplo-Dinamico rotational fan. Other manufacturers have tried to reproduce this unique design, though all have proven to be of lesser quality and durability. 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.Features: All Matthews Gerbar fans are hand made and not mass produced.Matthews rotational fans circulate heat and air conditioning more efficiently than traditional paddle fansConstructed of cast aluminum, heavy spun and stamped steel, this fan carries a limited lifetime warranty.Each Unique Motor Mount and Fan Head Knob is Made of Genuine Marbleized BakeliteLutron Decora-Style SFS-5E Fully Variable Wall Switch in White IncludedFlat ceiling canopy.
