Dyson Fan – An Innovative Bladeless Fan

The first time that a person looks at a Dyson fan without being aware of what it is they will probably wonder what sort of contraption it is, especially when it’s turned off. Its modern fashion-forward design is vaguely reminiscent of a wormhole that can transport people to other dimensions. The fan has a cylindrical base and a round or oval shaped “loop amplifier” which, in its entirety, looks like a giant magnifying glass.

The appearance of Dyson fans already makes them stand out. But what most people find amazing is that it’s a fan without blades. So, how does this bladeless fan work? The fan works through inducement and entrainment. At the bottom of the device, there are grills. This is actually where the fan motor is and it sucks in about 27 liters of air per second. This amount of air goes through the “loop amplifier” and is forced through the annular aperture that accelerates air flow. As the air is pushed through the loop amplifier, it also sucks in air from behind, which is the process of inducement. As this happens, air from around the device is also drawn into the stream of air, which is also known as entrainment. These processes make it possible for air to increase fifteen times the original amount of air intake. That’s why the Dyson fan is also known as the Dyson Air Multiplier Fan.

There are certain advantages and disadvantages of this air multiplier fan. Comparing it to the standard fan, it’s really the safer option as there are no spinning blades where children’s fingers can get caught in. People who have tried the fan also praise it for its peaceful and very tolerable hum as it emits a constant stream of air. Another benefit of this bladeless fan is that there is no buffeting of air. The usual fan has blades that create air pockets as these turn and slice through the air. So, the Dyson fan offers a refreshing breeze. Plus, it’s easy to clean and it doesn’t block out much light. This modern fan also has a dimmer switch for airflow adjustment and its stand can be readily tilted to the position desired. The main drawback of the Dyson air multiplier fan is that one can easily find a typical fan that can perform just as well or even better than this innovative device, at a really lower cost. Fans with conventional designs can be had for $20 or more, while the Dyson fan costs about $300 for either the 10-inch or 12-inch model.
