Energy Label for Eliza-H ceiling FanDesigned by Chicago architect Stephen Katz in 2014, the Eliza–H ceiling-mount fan blends a beautiful technically derived form with superior function and movement. The unique blade shape is designed to maximize air movement at the outer edge of the blade. The result is more efficient air velocity rings, less blade drag and greater motor optimization. Equally important is Eliza–H’s stationary visual statement which combines modern utility with minimalist geometry. Constructed of cast aluminum and heavy stamped steel, the Eliza–H has a limited lifetime warranty.
