This portable fan, the Seabreeze Turbo Aire, has an aerodynamic design inspired by a jet engine. It produces a high velocity airstream through an optimized blade shape and orientation.
The manufacturer claims it moves three times as much air as a comparable fan, while operating quietly. On a low setting, the Turbo Aire consumes just 65 watts, and on a high setting it uses about 110 watts. They say “at 20 feet, Turbo-Aire delivers over 11,000 cubic feet of air per minute”.
