So, how do bladeless fan works, device and principle of device operation ? you can find in this article

A few words about creating a bladeless fan

The model, radically different in its appearance from other types of fans , familiar to many from childhood, was invented in 2009. Its creator is James Dyson.

He worked for about 30 years on options for improving the vacuum cleaner and other household and industrial equipment. This English developer came up with many interesting and useful inventions, patents for which were sold to different countries of the world.

All his developments are distinguished by exquisite design and improved functionality. Mr. Dyson, while working to improve the hygienic hand dryer, took the principle of its operation as a basis for his new invention. So, in 2009, a special fan appeared that did not have blades.

About 4 years the leading engineers of J. Dyson’s company have spent on modeling a fan ring that can most effectively pass air through itself, multiplying it many times over.

The Dyson bladeless device was already on sale in the inventor’s homeland for 199 British pounds in 2010. Such a price can hardly be called popular, but there were many who wanted to acquire an innovative fan.

Therefore, now on the market you can find similar equipment from various manufacturers, including budget Chinese models.

Design and operation of a bladeless device

The fan without blades is also named after its maker, the Dyson fan, or the “Air Multiplier” as it was called. This ingenious innovation needs its ability to create a flushing air flow and to fuse perfectly with any interior.

The multiplier looks stylish, and the availability of analogues on the market makes it available to a wide range of consumers.

Constructive components of the air multiplier

Dyson’s air multiplier is capable of multiplying the air flow at the outlet. Moreover, the company’s engineers, designers and technologists create more advanced models that are able not only to blow off objects, furniture and people in the room, but also to perform the functions of cleaning and humidifying the air .

However, the price of such new products exceeds $ 300.

Bladeless Fan Models
Various manufacturers offer their fans without blades, differing in build quality, noise, functions and cost.

The device itself will differ depending on the model. After all, the more functions it can perform, the more buttons there will be on the control panel.

The fan without blades consists of the following parts:

  • body;
  • control Panel;
  • blower.

The housing contains a motor responsible for the operation of the device. Also on this part there are special holes through which air will be drawn in when the multiplier is turned on.

The appearance of the device for all manufacturers may differ significantly, as well as the size, functionality and cost

The fan can be controlled mechanically or electronically using the panel. In most cases, remote control is provided. Many models from various manufacturers are equipped with a remote control that works, on average, at a distance of 3 meters.

The control panel provides:

  • on and off button;
  • rheostat for adjusting the operating speed;
  • other buttons depending on multiplier model and manufacturer-provided functions.

The blower is round or oval. Its size depends entirely on the product model. This part of the fan can have a clear geometric shape or be in the shape of a heart, an apple, etc.

Air multipliers can be conditionally divided into 3 types according to the installation method:

  • outdoor;
  • desktop;
  • wall.

The first 2 types are portable devices, and the last one is stationary. Manufacturers often provide 2 options for one model: wall mounting and table mounting. In this case, the fan must be completed with brackets with dowels.

Dyson fan: How do bladeless fan works

Bladeless fans are capable of passing through themselves up to 500 liters of air in 1 second. The outlet stream is evenly distributed, gently enveloping the entire space. During visual inspection, moving parts outside the operating device are not visible. At first glance, this is exactly what an air multiplier looks like.

The principle of such efficient operation of a bladeless fan is to multiply the drawn in air at the outlet. This is due to the special shape of the blower and the presence of a specially shaped hollow channel inside it.

The shape of the fan air duct is half as wide on one side as on the other. This allows the air to significantly increase its speed as it travels through it.
The shape of the fan air duct is half as wide on one side as on the other. This allows the air to significantly increase its speed as it travels through it.


First, a high-speed motor draws air through small holes at the base of the instrument. This air then moves to the blower duct. The shape of the channel is designed on the same principle as an airplane wing. Therefore, when air moves inside the channel, its speed increases.

Special air channel shape
The special shape of the air channel and the design of the device itself allow to multiply the volume of air passing through it (+)

The air exits the channel from the narrower side, and a low pressure area forms on the opposite side. This ensures that air is actively drawn inward, the volume of which is 15-20 times greater than the initial air drawn in by the engine.

As a result, people in the operating area of ​​the device are blown much more strongly than when using a conventional paddle fan.

Features of using the multiplier

The scope of using a fan without blades is very wide – it is a home, office, summer cottage, kindergarten, hospital or other municipal institution. The exceptions are bathrooms , rooms with a swimming pool, saunas, baths. It is important to ensure efficient removal of wet vapors there.

The fact is that the device is safe if it is used by capable members of society. Otherwise, use is permitted under the supervision of adult citizens.

The device copes well with the functions of a fan, and more advanced models can act as real air conditioners

In addition to gently distributing the multiply increased airflow, a fan without blades can humidify air and cool / heat. The user sets the moisture percentage in the settings. The adjustment range depends on the model of the device and fluctuates, on average, from 30 to 70%.

As for the heating or cooling function, it is available in more expensive models. The desired parameters are specified by the user. You can also choose a model that can clean the air from harmful impurities, for example, from smoke or fumes.

Manufacturers of even the cheapest models prefer to complete their devices with remote controls

The HVAC equipment market is replete with offers of various models of bladeless fans from many manufacturers. Among them, there are both affordable models costing up to $ 100, and expensive options of well-known brands with the functions of a real air conditioner or split system .

Among the manufacturers offering their bladeless equipment are the following companies: Flextron, SUPRA (Supra), UNISVET, Clever and Clean, Roward, Dyson, Coolguy, Aaron, RENOVA, Orion, Bladeless, BiLux, MAGNIT.

The price range of bladeless devices of these companies is from 2,000 to 35,000 rubles or more.

An important characteristic influencing the level of comfort when using a fan is the noise level. It can be 40 dB, 55 dB, 60 dB or more. This is the most important parameter that should be taken into account before buying.

fan noise less than 60 dB fan noise less than 60 dB

When the fan noise is 60 dB or more, a person will get tired after an hour of work and may have a headache

Manufacturers indicate the noise level of a particular model in the technical specifications. Moreover, this is the maximum level that is achieved when the equipment is operating at maximum speed. For cheap devices, the declared noise level may not correspond to reality.

Pros and cons of bladeless fans

The air multiplier has advantages and disadvantages identified by users.

Among the positive aspects are:

  • safety;
  • uniform air flow;
  • minimal electricity consumption;
  • convenient control;
  • ease of care;
  • stylish design.

Safety is ensured by the absence of blades and other moving parts outside the product. Also, thanks to the motor located at the bottom and the absence of vibration from the rotation of the blades, the entire structure is stable.

Electricity consumption is most often 25 W and 40 W. Models with other characteristics are less common.

The control of the device is simple and straightforward. All the subtleties of adjusting the purchased model are described in detail in the instructions. The air flow rate of the bladeless fan is also adjustable.

Manufacturers do not recommend constantly setting maximum settings when using a fan without blades, so as not to overload it

In addition to the advantages, the bladeless device has its disadvantages:

  • Noise effect – sound level from 40 dB. The larger and more powerful the device, the louder it will hum at maximum speed.
  • High price. The equipment loses in this indicator to the usual paddle fans.
  • The fragility of the structure. This disadvantage is typical for inexpensive Chinese-made counterparts.

Manufacturers strive to take into account all the shortcomings and wishes of customers, improving new fan variations. So, first, consumers were offered various colors and sizes, then – the most intricate form. Later it was the turn to minimize the noise level produced by the device.

The next challenge was to reduce energy consumption and add additional functions for humidification and heating / cooling of air passing through a bladeless fan.

Aromatization and ionization of air flows so far exist only in expensive models of the latest generation

Diy bladeless device

After you understand how do bladeless fan works, let’s try to make this device yourself.

The question of creating a fan without blades with your own hands was visited by many craftsmen. In the course of experiments, home craftsmen have obtained many working homemade products.

Option # 1: product from plastic buckets

For the manufacture of the device, a plastic container, a simple fan and a glue gun are used.

From simple and affordable materials, in a couple of hours you can build a homemade fan without blades

For example, you can take:

  • 2 plastic buckets with a volume of 5 and 10 liters;
  • PVC pipe 110;
  • distribution tee;
  • stub.

First, you need to cut a piece 15 cm long from the pipe. Then, in a 10-liter bucket, make a hole on the side exactly the same size as the outer diameter of the pipe.

Using a glue gun, carefully and carefully connect these 2 parts together

The next step is to take a 5 liter bucket and cut 3 cm from the top edge. We still have to cut a hole in the bottom, the diameter of which is 2 cm less than the very bottom of the bucket. In the bottom of the larger bucket, you also need to make a hole of the same size and connect them together with a glue gun. This is a homemade blower.

Now we have to assemble a case with a motor, the role of which will be played by an axial fan. To do this, put a plug on the side branch pipe of the tee, having previously applied an adhesive layer there.

It is better to leave a small gap of 1.5-2 cm so that there is air access. Then you need to put the PVC pipe on one of the branch pipes of the tee and mark the border – this will be a segment of about 10 cm to be cut off.

Place the cut-off piece in this branch pipe and make a through hole 5 cm long from the edge

It is here that an axial electric fan of the required diameter will have to be installed, and a wire will be brought out into the hole to be connected to the electrical network.

To give the finished homemade product an aesthetic look, all parts can be painted in one color with aerosol enamel. For example, in white, beige or blue. The case is ready to be connected to the network.
