Dyson air multiplier

The Dyson Air Multiplier is a fanless fan invented by the famous British scientist Sir James Dyson. The invention was inspired by the hand dryer. After the launch of the "Dyson Air Multiplier", public opinion agreed that this new fan is expected to completely replace the traditional fan.

The inside of the fuselage of the air multiplier has a ring-shaped slit with a width of only 1.3 mm. Between these small gaps, the air flow is close to the inner wall while the Coanda effect causes the air flow around 15 times to "blob" the cool breeze, which can reach 35 kilometers per hour.

In fact, the so-called air multiplier uses the principle of a jet pump (ejector). A high-pressure air jet is used to draw a surrounding area of air behind the nozzle to draw ambient air.
