Can a fan still cool you if it doesn’t have blades?
Apparently so, if it’s the new Dyson Air Multiplier ™ fan pictured above.
Dyson, a company well-known for advancing vacuum cleaner technology, has now developed a new generation of innovative bladeless fans. These fans use the simple principles of fluid dynamics –without the traditional fan blades –to multiply air flow 15 times, ultimately expelling some 119 gallons of air every second.
What more, since there are no blades, the Dyson Air Multiplier ™ fan is safe and easy to clean. Air flow is uninterrupted, and velocity is adjusted with a control similar to a dimmer switch.

How does it work? The Dyson website explains it like this:
1. First, an energy efficient, brushless motor draws air in using technologies similar to those at work in jet engines and turbochargers.
2. Airflow is accelerated as it passes over an airfoil-shaped ramp.
3. Air from behind the fan is drawn in by a process known as inducement.
4. Air from around the fan is also drawn in by a process known as entrainment. Altogether, the airflow is amplified 15 times.

Technology like this isn’t cheap, however. The 12” version of the Dyson bladeless fan is available for $329.99. The 10” version will set you back $299.99
