Height is adjustable across a 15 inch range on this copper pedestal fan, from 34.5 inches for desk-level air to 49.5 inches when the breeze needs to clear a sofa back. Three speeds move 900, 1100 or 1400 CFM at motor speeds of 1000 to 1300 RPM, with 75 degree horizontal oscillation and a 20 degree tilt to place the airflow where it belongs. The frame, four blades and weighted base are metal, which keeps the 13 lb fan planted when the head swings. A tight safety fence guards the blades. It measures 17.5 by 15.5 inches at the base, draws 55W on 110 to 120V through a 6 ft cord, and runs at 65 dB or less.
