This is how Dyson Cool bladeless fans work

Dyson AM07 Cool fan

The British company Dyson is one of the most innovative and exciting brands on the technology scene. Their designs almost always have the virtue of surprising us and tend to have a futuristic halo that is very easy to recognize. But always with one idea ahead: utility. It was with that idea that Dyson bladeless fans were born . Equipment capable of offering the same performance as a traditional fan but with up to 75% less noise.And ending the dangers of blades for the smallest of the house. But how do they work? Where does the air that seems to come out of nowhere come from? We get into the bowels of one of these teams to explain the whole process from when the air enters until it leaves and we summarize the main characteristics of each model.

It all starts with the intake holes , which are placed under the metal ring. These holes surround the equipment and are designed so that air is absorbed evenly. The Dyson motor works quietly thanks to the use of a special cavity called "Helmholtz" shaped like a bowl, which dissipates sound for quiet operation. As a curiosity, it must be said that the Helmholtz cavity comes from the world of music. Along with this motor construction we have a housing that has been acoustically designed to reduce fan vibrations.

But there is not the work of the engineers to reduce the noise of the equipment. The fins on this engine are asymmetrical and fit well together to harmonize movement and have rounded edges to improve acoustics. When air passes through here, the engine is able to separate the airflow into different layers in an orderly fashion. In this way, the same amount of air reaches both sides of the ring. The bottom of this hoop has a greater volume. This decision has been made to make the flow inlet quieter and then channel through the circular cavity steadily. The different air pressure depending on the power we give to the motor will cause a stronger or weaker current through the rim.

And we get into the final key element for this fan to work. When the air comes out through the opening of the ring, it automatically adheres to the aerodynamic ramp that is responsible for directing and projecting the flow in the correct direction. This same circuit is the one that attracts the surrounding air to the ring and creates a greater current. And what are the advantages of this technology? On the one hand, we have already talked enough about the ability to achieve quieter operation. According to Dyson , up to 75% quieter than traditional fans . In addition, the fact of removing the blades also results in a fan that is much easier to cleanand without the dangers of little ones sticking their finger where they shouldn't. Finally, thanks to this technology the air flow is more constant, which creates a more pleasant sensation when used. In short, a magnificent piece of engineering with which Dyson has once again revolutionized the market.

Table fans

We begin our review of the most compact Dyson fans to place on any table. To cool off in the summer or to warm up the room in winter, these versatile machines are the ideal work companion.

Dyson AM05 Hot & Cool

Dyson AM09 Hot + Cool

The Dyson AM09 Hot + Cool is the most versatile bladeless fan of the British company. This equipment is capable of working both as a fan and as a heater. Thanks to its compact design we can place it on any desk and regulate it to enjoy its two functions. In addition, it includes a thermostat to work only until reaching a certain temperature and then maintaining it. We had the opportunity to test the Dyson AM09 Hot + Cool in depth and it must be admitted that the power that this device reaches despite its size is surprising. As for the official figures, it is capable of transmitting a maximum air flow of170 liters per second with up to 10 different power levels. And all this, of course, with the possibility of using a small remote to configure it comfortably.

The overall dimensions of this model are placed in  15.3 x 57.9 x 20 cm and its weight rises to 2.36 kilos. It is available on the market in both black and silver .

In this case, the Dyson Cool AM06 fan focuses on the fan function . This is a model with a more rounded and compact, with dimensions of 55.2 x 30 x 14.5 centimeters and a weight of 1.83 kilos. This device is capable of launching the airflow to a maximum distance of up to 3.7 meters. Like its brother, it has ten different power levels that can be regulated through its remote control or through the fan panel itself. Or a timer to keep the fan running for a while and then turn it off automatically (between 15 minutes and 9 hours ). The Cool AM06 it is available in black or silver.

Stand and tower fans

Now, if what we want is a more powerful fan and place it in any corner of the room to work from the floor, the British company offers us several models in a standing or tower format.

The AM07 fan bets on the tower format. It is a device that uses an oval-shaped metal ring that achieves a flow of up to 500 liters of air per second . This team has a considerable height that borders the meter and that reaches a weight of 2.85 kilos . In addition, it includes up to ten power levels that can be controlled both through its small remote control and through the integrated panel inside the fan itself. All this with up to 60% quieter operation than the previous generation model.

Dyson Cool AM08

Dyson Cool AM08

A floor-standing fan with a slim and elegant design that works well in any home. In addition, it can be found on the market in two shades: silver or black . One of its advantages over table fans is very obvious. And is that compared to the airflow of 170 liters per minute of the AM09, the Dyson Cool AM08 is capable of reaching a flow of up to 600 liters per second. Of course we are also talking about a rather less comfortable transport model and place at home, as it has a height of 141 centimeters and weighing 3.87 kilos. Of course, thanks to the length of its cable of up to two meters it will be easier to place in any room. This fan has ten power levels and a small knob to control its operation.
