This is Dyson’s latest invention: The Dyson Air Multiplier™.The fanworks very differently to conventional fans. It uses Air Multiplier™
technology to draw in air and amplify it 15 times, producing an
uninterrupted stream of smooth air. With no blades or grill.
Air is accelerated through an annular aperture. This creates a jet of air that passes over a 16° airfoil-shaped ramp, channeling its direction. Using an airfoil-shaped ramp (like a cross-section through an airplane wing), airflow is amplified 15 times.
