Dyson the creator of the well know vacuum cleaner has just launched the world’s first bladeless fan. The Dyson fan has no blades which mean no need for a grille and it’s safe and simple to use and clean. Air is drawn into the base of the machine.
The air is forced up into the loop amplifier and accelerated through the 1.3mm annular aperture, creating a jet of air that hugs the airfoil- shaped ramp.
Dyson engineers spent four years building and perfecting Dyson’s Air Multiplier technology. Air fluctuations were mapped with Laser Doppler Anemometry, helping measure control the machine’s airflow.
