This is the tower fan that uses technology found in jet engines to generate a soothing air stream without any blades. The bladeless fan produces a smooth, uninterrupted stream of air, unlike typical fan blades that "chop" air into uneven, intermittent breezes. A turbine inside the base draws in air and propels it up to the loop amplifier. Air is expelled through a 1-mm slot along the circumference of the loop amplifier and across a 16º airfoil-shaped ramp, resulting in 16X more air velocity. The fan draws air from behind and along its sides into the air stream and produces a smooth, uninterrupted stream of air, unlike typical fan blades that "chop" air into uneven, intermittent breezes. The fan oscillates 80º and a dial allows smooth, continuous adjustment of air velocity. Includes a remote control and a 6 1/2'-long cord. 39 3/4" H x 7 1/2" W x 4 1/2" D. (7 1/2 lbs.)
