Have you ever seen a Dyson Fan and wondered how it works especially since it does not have blades like a normal fan? Due to this unique bladeless quality, the scope for unique design has allowed Dyson to sculpt an amazingly elegant and curious device which will have every person that visits you at your house asking what it is and then staring at it in disbelief.

This article will briefly explain how this device works and we’ll also delve into its unique properties.

As you know, traditional domestic cooling fans have blades to propel the air around the room, hence producing a cooling effect. In addition the conventional fans also produce buffeting which is caused by the blades cutting through the air.

The Dyson fans however do not have blades. As a matter of fact they look hollow and you can even put your hand or head through them just like a hoola-hoop with no danger of physical harm.

So how does this device propel air when it has no apparently visible means to do so?

Well it all happens using what Dyson call their Air Multiplierâ„¢ technology. Dyson say that they have used some of the technologies found in jet engines and turbo-charge units to produce a powerful airflow.

But how does this airflow happen when there aren’t any moving parts to be seen?

The base of the fan unit has a brushless electric motor which sucks in the air from the surroundings and delivers it into the hollow circular tube. The air in the tube then accelerates through the enclosure until it reaches an opening which has a shape based on the wings of an aircraft, and is then channeled to the outside, producing a breeze.

Then by the sheer laws of nature and physics, the surrounding air is also attracted into the airflow stream produced by the fan, hence creating a breeze. Dyson claim that their fans produce around 15 times more airflow than the air originally surrounding the device. Dyson call this process of airflow, “inducement”.

A by product of the way the airflow is generated by the Dyson fan is that there is no buffeting like there is with conventional fans. The air is delivered more consistently and steadily because its flow is not created by the vigorous spinning of blades.

 

 

 

 

 

 

The brushless motor which draws the air from the surroundings actually has 9 blades but they are hidden from view. The blades are aligned asymmetrically and it is due to this design that they are able to suck in around 20 liters of air per second.

Dyson has 3 main categories of these types of fans in its range.

They include:

AM01 Table Fans

This category of Dyson Fans is available in 10 or 12 inch and is designed for small rooms and desks. They have a dimmer switch which allows you to set any power setting of your choice within the range.

AM02 Tower Fans

The tower fan which measures 39.7 x 4.3 x 7.5 inches, has a cool shape and oscillates up to 360 degrees to cover a whole room.

AM03 Pedestal Fan

As you can see the sheer aesthetic beauty of these fans is almost reason alone just to get one for your living room but the fact that it also has a practical use is even more enticing.
