The AM02 Tower Fan and AM03 Pedestal Fan from Dyson creates a breeze of cool air in larger spaces and uses the company’s Air Multiplier technology, which replaces fast-spinning blades and grilles with loop amplifiers. The AM02 Tower Fan is oval-shaped and less than 3' tall and a 1' wide; it draws nearly nine gallons of air per second and amplifies it 16 times. The AM03 Pedestal Fan (shown) has an 8-3/5" extension and also takes in nine gallons of air, which it amplifies 18 times, making it most suitable for larger areas such as living rooms and offices.
