Greetings, friends! Today I will talk about an unusual bladeless fan. The windows of my office are located on the sunny side, and in the summer it is incredibly hot there. The management is not yet ready to allocate funds for an air conditioner, but they still approved the purchase of a fan for me.
I haven’t had to choose such devices before, so I don’t understand much about them. I needed a compact desktop model, and I began to look at what was being sold on the Internet. Suddenly I came across a very interesting thing– bladeless fan. I didn’t even know about the existence of such devices before; it looks so unusual that it rather resembles some kind of object from the future or a detail of interior decoration.
The entire design of such a fan consists only of an empty plastic ring and a stand on which it is mounted. I myself would never have guessed what kind of device it was or how it worked. However, judging by the manufacturer’s information and numerous rave reviews, the bladeless fan performs its functions very effectively and, in addition to its ultra-modern design, has many other advantages over traditional devices.
Another important thing for me was the fact that such models have small sizes, and, unlike bulky designs with blades and grilles, will not take up much precious space on my desktop.
Thus, I immediately decided that a bladeless fan was exactly what I needed and decided to choose it. When the order was delivered, I immediately unpacked the box and took out the device from it. It looks just as cool in real life as it does on a computer screen. I immediately decided to try it out, because until the last moment I had doubts about how this simple-looking ring on a stand without any moving parts could serve as a fan.
But, surprisingly, the device not only works, but also does it very well.
A fairly strong stream of air emerges from the ring, and this stream is very similar to real wind due to the fact that it is continuous and uniform. Sitting in front of such a fan, feeling the breeze, is much more pleasant than in front of a device with blades, from which the air comes out in gusts.
As has already become clear, I am very pleased with my new fan, now I will describe its characteristics in more detail.
My review of a bladeless fan
Characteristics:
I have already mentioned that the design of the fan is very simple, it consists of only two parts - a wide hoop and a cylinder-shaped stand, made of high-quality plastic. The body color has many color options, I settled on neutral white.
Device dimensions:
- The diameter of the ring is 12 inches (this is approximately 30.5 cm);
- Fan height – 55 cm.
- The device operates from the mains power supply.
In order to create for yourself the most comfortable conditions, you can adjust the power of the outgoing air flow. Using a movable mechanism at the base of the fan, it can be tilted forward or backward and rotated to the sides. The tilt angle is 10 degrees, the rotation angle is 90 degrees. You can also select automatic rotation mode. The fan is controlled using a remote control, which is very convenient. The remote control runs on two AAA batteries.
Packaging and accessories
The fan was packed in a colored cardboard box. Inside the box, the parts were securely secured in a foam mold.
In addition to the device itself, the package includes a remote control remote control and detailed instructions.
Operating principle of a bladeless fan
A fan without blades is a relatively new invention of the brilliant James Dyson, who is the author large quantity non-standard solutions to common everyday problems.
I'm not a big fan of physics, but now I'll try to explain how this device works, based on the information that I studied before buying it. The secret is that the fan ring is not even in shape, but is made according to the laws of aerodynamics, i.e. on the same principle as airplane wings. There are also special slots for air in the ring.
There are also holes at the base of the fan, through which air from the room is sucked in by a small turbine and pushed out into the ring. The air then spreads along the inner contour of the ring and escapes out through the cracks. Thanks to this jet and the special shape of the ring, a zone with negative pressure is created inside, which, like a pump, captures air from the back side and throws it forward in a powerful and even flow with an increase of fifteen times. This air flow is enjoyed by a person sitting in front of a bladeless fan.
Why choose a bladeless fan
In addition to its stunning design, a bladeless fan has other advantages over traditional models:
Safety. It is absolutely safe because it has no exposed moving parts. I think this device is ideal for home use. It can be safely used even in rooms where there are children or pets.
Sustainability. The device is a very stable design due to the fact that its heaviest part, the motor, is located at the bottom. The main weight of fans with blades is concentrated at the top, so they can fall even with a slight push.
Low power consumption. The bladeless device consumes 98% less energy compared to conventional fans. Taking into account today's tariffs, significant savings are obtained.
Uniform air flow. This stream is much softer, more pleasant, and also healthier than the intermittent and vibrating stream emanating from rotating blades.
Easy cleaning. Fans with blades accumulate a lot of dust, and cleaning them takes quite a lot of time, because there is a lot of small parts, and in order to get to the inside, you need to remove the grille. To clean the bladeless device, you just need to wipe the ring with a damp cloth, which only takes a few seconds.
I've been using the bladeless fan in my office for a few weeks now and am very happy with it so far. The fan takes up very little space on the desk, operates quietly and does not distract attention. The device is very powerful, I usually set the regulator to the smallest or medium level and this is quite enough. The air flow that comes out of the device is very light, pleasant, does not dry out the skin and eyes, and at the same time saves you from the heat. And I’m simply delighted with the design, there has never been a person who would walk into an office and not pay attention to a fan without blades; it evokes delight, interest and a bunch of questions in everyone.
Advantages:
- unusual and stylish design;
- compact dimensions;
- uniform air flow;
- safe design;
- low power consumption;
- easy cleaning;
- remote control using a remote control.
Flaws:

I advise everyone who does not yet have a bladeless fan to purchase one! This is a great device that is compact and beautiful.
One of the new products on the climate equipment market is a bladeless fan. The device simultaneously arouses interest and doubt among potential buyers. Unusual bladeless fan surprises appearance and functionality.
Some people decide to purchase it, while others worry that the money will be wasted. To dispel doubts about the performance of the equipment, you need to take a closer look at its structure, operating principle and operating features.
The model, radically different in appearance from others familiar to many since 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 in different countries peace.
Bladeless models allow you to relax peacefully, enjoying the coolness and without worrying that one of your pets or children will get hurt if they get caught in the fan blades
All of his developments are distinguished by exquisite design and improved functionality. Mr. Dyson, 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.
J. Dyson's leading engineers spent about 4 years simulating a fan ring that could most effectively pass air through itself, multiplying it many times over.
Already in 2010, a bladeless device from Dyson was sold in the inventor’s homeland for 199 British pounds. This 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.
In the near future, users will be able to try a new product - ceiling option bladeless fan. This is Exhale Fans equipment designed by Nick Heiner
Design and operation of a bladeless device
A fan without blades is often called a Dyson fan in honor of its creator or, as he himself called the device, an Air Multiplier. This original invention is in demand due to its ability to create a uniform air flow and fit perfectly into any interior.
The multiplier looks stylish, and the presence of analogues on the market makes it accessible to a wide range of consumers.

Structural components of the air multiplier
The Dyson 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 can not only blow air over objects, furniture and people in the room, but also perform functions.
However, the price of such new products exceeds $300.
Different manufacturers offer their fans without blades, differing in build quality, noise level, features and cost.
Depending on the model, the device itself will differ. After all, the more functions it can perform, the more buttons there will be on the control panel.
A fan without blades consists of the following parts:
- frame;
- control Panel;
- blower
The housing contains a motor that is responsible for the operation of the device. There are also special holes on this part through which air will be drawn in when the multiplier is turned on.
The appearance of the device from all manufacturers may differ significantly, as well as size, functionality and cost.
The fan can be controlled mechanically or electronically using a panel. In most cases, remote control is provided. Many models from various manufacturers are equipped with a remote control that operates, on average, at a distance of 3 meters.
The control panel provides:
- on/off button;
- rheostat for adjusting the speed of operation;
- other buttons depending on the multiplier model and the functions provided by the manufacturer.
The blower has a round or oval shape. Its size depends entirely on the model of the product. This part of the fan can have a clear geometric shape or be in the shape of a heart, apple, etc.
The whimsical shape of a bladeless fan will allow it not only to be a useful device in the room, but also to become an original element of decor
Air multipliers can be divided into 3 types based on installation method:
- floor;
- desktop;
- wall-mounted
The first 2 types refer to portable devices, and the last one to stationary devices. Manufacturers often provide two options for one model: wall mounting and table mounting. In this case, the fan must be equipped with brackets and dowels.
When hanging the device on the wall, it is important to use the components offered by the manufacturer. Otherwise you may lose your warranty
Dyson fan: operating principle
Bladeless fans are capable of passing through up to 500 liters of air in 1 second. The outlet flow is evenly distributed, gently enveloping the entire space. During a visual inspection, no moving parts are observed outside the operating device. This is exactly what an air multiplier looks like at first glance.
The principle is efficient work a bladeless fan is to multiply the drawn air multiple times at the outlet. This occurs 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 channel on one side is half as wide as on the other. This allows the air to significantly increase speed as it moves through it.
First, a high-speed motor draws air through small holes at the base of the device. This air then moves into the blower channel. The channel shape is designed on the same principle as an airplane wing. Therefore, when air moves inside the channel, its speed increases.
The special shape of the air channel and the design of the device itself make it possible to repeatedly increase the volume of air passing through it (+)
Air exits the channel from the narrower side, and an area is formed on the opposite side low pressure. This ensures that air is actively drawn in, the volume of which is 15-20 times greater than the original drawn in by the engine.
As a result, people in the operating area of the device are blown much stronger than when using a conventional blade fan.
Features of using a multiplier
The scope of use of a fan without blades is very wide - home, office, cottage, kindergarten, hospital or other municipal institution. The exception is premises with a swimming pool, saunas, baths. There it is important to ensure effective removal of wet vapors.
The fact is that the device is safe if it is used by capable members of society. Otherwise, use is permitted under adult supervision.
The device adequately copes with the functions of a fan, and more advanced models can serve as real air conditioners
In addition to the gentle distribution of multiply increased air flow, a fan without blades can humidify the air and cool/heat. The user sets the humidity percentage in the settings. The adjustment range depends on the model of the device and ranges, 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 purify the air from harmful impurities, for example, smoke or fumes.
Manufacturers of even the cheapest models prefer to equip their devices with remote controls
The climate control equipment market is replete with offers of various models of bladeless fans from many manufacturers. Among them are both affordable models costing up to $100, as well as expensive options from well-known brands with the functions of a real one.
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 from these companies is from 2,000 to 35,000 rubles or more.
An important characteristic that affects 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 purchasing.
When the fan noise is 60 dB or higher, a person will feel tired and may have a headache after just an hour of operation.
Noise level specific model manufacturers indicate technical specifications. Moreover, this is the maximum level that is achieved when the equipment operates 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 its 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 below and the absence of vibration from the rotation of the blades, the entire structure turned out to be stable.
The special shape of the blower ring allows the fan to gently and evenly distribute air flow throughout the room
Electricity consumption is most often 25 W and 40 W. Models with other characteristics are less common.
Operating the device is simple and straightforward. All the details of adjusting the purchased model are described in detail in the instructions. The air flow power of a bladeless fan is also adjustable.
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 buzz at maximum speed.
- High price. The equipment is inferior in this indicator to conventional blade fans.
- Fragility of the structure. This drawback is typical for inexpensive Chinese-made analogues.
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 shape. Later it was time to reduce the noise level produced by the device as much as possible.
The next task 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 currently only exist in expensive models of the latest generation
DIY bladeless device
The question of creating a fan without blades with your own hands has visited many craftsmen. During the experiments, home craftsmen obtained many working homemade products.
Option #1: product made from plastic buckets
To manufacture the device use plastic container, a simple fan and a glue gun.
From simple and available materials you can build it in a couple of hours 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, you should 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 smaller than the bottom of the bucket itself. You also need to make a hole of the same size in the bottom of the larger bucket and connect them together glue gun. This is a homemade blower.
Now we have to assemble a housing with a motor, the role of which will be played by an axial fan. To do this, put the plug on the side pipe of the tee, having previously applied an adhesive layer there.
It is better to leave a small gap of 1.5-2 cm to allow air access. Then you need PVC pipe put it on one of the tee pipes and mark the boundary - this will be a segment of about 10 cm that needs to be cut off.
Place the cut piece into this pipe and make through hole 5 cm long from the edge
This is where the axial shaft is to be placed electric fan the required diameter, and lead the wire into the hole to be included in electrical network.
To give the finished homemade product an aesthetic appearance, all parts can be painted in one color with spray enamel. For example, in white, beige or blue. The case is ready to connect to the network.
All that remains is to place a homemade blower from 2 buckets on top and turn on the fan
If you place a container with ice inside the case, the homemade product will act as an air conditioner. And when placing a piece of cotton wool with 5-7 drops essential oil You can fill the whole room with a pleasant aroma.
Option #2: fan made of plastic pipes
The prototype of the second option was a bladeless device of the brand Dyson. The body and technical part were assembled by a home craftsman according to the diagram finished product factory production.
Let’s start building a homemade product useful in everyday life with the body:

Care and maintenance of the device
A fan without blades can last the period stated by the manufacturer in the instructions only if the rules of its operation are followed. It is easy to use and maintain. It is important to use the device for its intended purpose and not to move it from place to place during operation.
If you need to rearrange the equipment, then you should grab it by the body, and not by the blower.
To maintain the air multiplier, it is enough to periodically perform the following actions:
- clean the blower holes with a brush to prevent them from clogging;
- Wipe the blower and the device body with a damp cloth, removing dust and other contaminants.
Maintenance should be performed as needed. Use special cleaning agents or detergents not required - the surface of bladeless fans can be easily cleaned with a damp or dry soft cloth.
When operating the device, do not forget about safety measures and under no circumstances use it if it breaks down.
If a malfunction is discovered, you should contact specialists authorized to repair climate control equipment from a specific manufacturer.
Attempt self-elimination Failure may result in loss of warranty for the fan. If you lack experience in repairing such devices, you can cause even more damage to the equipment.
You can see how to assemble a fan without blades from scrap materials in the following video:
A fan without blades can be made from scratch, spending a minimum of effort and materials. Step-by-step instruction assembly video:
Having examined the features of the design and operation of a bladeless fan, having become familiar with model range different manufacturers, you can form your own opinion about the device. Products from famous companies They are not cheap, but they are quite capable of replacing an air conditioner.
Cheaper analogues make loud noise, squeak and may not provide the performance indicated in the instructions.

When the thermometer begins to exceed the thirty-degree mark in the summer, the only thing you want to do is find a cool place where you can escape from the unbearable heat. A familiar situation, isn't it? There are different ways to escape the heat. Someone constantly uses cold water, someone goes on vacation and does not go out to sea, and the hardest thing is for those people who work indoors or are forced to stay at home. Therefore, many will probably be interested in such a thing as a bladeless fan. Compared to an air conditioner, its cost is significantly less, and besides, it can be installed anywhere. A original design Such a device will decorate the interior of any room.
How does a bladeless fan work?
The essence of the ideas underlying the development of all household appliances, regardless of the years, remains the same. All that technical progress can give is only their modification and improvement. And the bladeless fan is no exception. The cunning device owes its birth to the American inventor James Dyson. It was he who came up with the idea to create a device for moving air that has neither blades nor any moving parts.
How then does a bladeless fan work? The operating principle of this device was borrowed from a hand dryer, to which we have long since become accustomed. When we place our hands under it, the air flow begins to move with great strength and involves air layers located in close proximity to it. The bladeless fan is shaped like an aerodynamic ring, which is located on a small stand. An electric motor is installed inside. In the aerodynamic ring itself there is a very narrow gap with a width of only 1.3 mm. The turbine pumps air into it with enormous force. Inside the structure is formed high pressure, and the mixture of gases begins to escape through the gap at high speed. As a result, a rarefaction zone appears opposite the center of the ring, which draws in the surrounding air.
What is good about a bladeless fan?
Rich colors and modern design similar devices allow you to choose a model in accordance with any tastes and preferences of customers. The body can be either plastic or chrome. And some models even have built-in lighting. Most important advantages What a bladeless fan can boast of is silent operation, adjustable blowing speed, uniform and smooth air movement. The absence of grilles and blades in the body makes cleaning quick and easy, and the low center of gravity gives the device excellent stability. Air supply can be done at different angles, and the presence of a remote control will certainly appeal to those who are accustomed to comfort. An equally important characteristic is operational safety. A bladeless fan can be left on without any fear in a room where there are children or pets. All this does this device very useful.
Quite recently, rather strange devices have begun to appear on the market that have the functions of a regular fan, but do not have the usual blades. A standard device of this type looks like a ring mounted on a special stand. In this case, the air flow comes directly from the middle of such a ring, which seems fantastic and even magical. For many, such a fan causes bewilderment, while others consider its operation to be simply supernatural or a scam.
In fact, a fan without blades has a rather simple device, although its operating principle is based on latest developments in Aerodynamics and Engineering. The fact is that the ring installed on the cabinet is hollow inside, and a special hole is made along its inner perimeter. A fan without blades has a turbine inside the cabinet, which supplies air pressure inside the ring, and it exits through an opening that has such aerodynamics that its flow is directed in a certain direction, namely through the circle itself. Thus, directional masses are created, which, in turn, capture air from environment, creating a fairly powerful flow. Therefore, such a device is often called pressure."
It is worth noting that the air flow obtained using such a device flows evenly, and not in portions, as when using a conventional fan, which helps to increase its efficiency and significantly improves efficiency. Therefore, such a device is very good to use as a cooling fan. Its uniform flow will keep the required area under constant air pressure, which will be much more efficient at the same energy costs.
Thanks to its design, a fan without blades allows you to produce an air volume 15 times more than a regular one. At the same time, his air pump It works almost silently, which is also a very big advantage. Many models of such devices can heat the air, allowing the device to be used as a heater, and the absence of blades makes it safe for children.
However, the most important advantage of such a fan is its uniform air flow, which can be compared to a light breeze; it makes you feel like you are on the seashore. It does not bother you with its constant noise, so using such a device is a pleasure. Also, a fan without blades does not collect dust. This has a positive effect on health and will make it possible for people suffering from allergies to use it.
Thus, bladeless fans are the latest home organization devices that are not only very efficient, but economical and safe. At the same time, the price for such air is almost the same as for an electric fan heater. This makes such a device accessible to almost everyone, and the remote control will allow you to enjoy a gentle air flow from anywhere in the room.
Innovations quite aggressively and intrusively invade our lives. A happy exception was the appearance of an “air multiplier” on the market of household appliances. A striking innovative device, a fan without blades, turned out to be extremely comfortable to use, efficient and economical, and it easily won the sympathy of consumers.
Mysterious "air multiplier"
The bladeless fan was a bold step in the evolution of climate-controlled home appliances. The honor of the invention belongs to the Englishman James Dyson, an engineer and industrialist, the author of a huge number of non-standard discoveries in solving everyday everyday problems.
Watching how the blast of air from the slot of a hand dryer captured nearby layers of air and pulled them into its flow, he became fascinated with the idea of creating a bladeless fan. A long path of research and development, intellectual and financial expenditures was passed before the device appeared on the shelves and fascinated everyone with its mystery.
Now the assortment of store shelves household appliances represents a whole assortment chain of bladeless fans. They differ in power, purpose, design, and there are models to suit every taste and budget. Devices from Dyson cost up to 25,000 rubles, economic analogues from other companies cost up to 2,500 rubles. There are desktop and floor structures, models with a diffuser in the form of a simple ring, in the shape of a heart, an apple, a diamond, in the form of the contours of funny children's toys. Models are equipped with a remote control.
Design features
A fan without blades consists of two main parts:
- grounds;
- ring diffuser.
A high-speed turbine is mounted into the base of the device, equipped with a 40 W engine, with which it has a common shaft. The turbine provides air movement in the device. The engine is equipped with a Hemholtz chamber to capture and dissipate engine noise. The base housing of the device has many holes for air intake.
The fan ring diffuser is made according to the laws of aerodynamics. There is a special slot in the ring on its inner surface through which air is pumped into the work surface. The cross section of the diffuser ring is a drop. This shape is aerodynamically ideal from the point of view of minimizing drag; turbulence zones do not form around it.
Fan without blades: operating principle
The device uses the technological principle of an air turbine. Located at the base of the device, the turbine, through the technological holes in the base housing, sucks in air from the outside and supplies it through a narrow slot into the annular diffuser. The specially adapted profile of the diffuser ring increases the efficiency of the pressure difference, resulting in air being pushed out with force due to the aerodynamic effect. At the same time, the air surrounding the diffuser ring is drawn into the resulting flow; due to this, the working flow increases by 1.5-2 dozen times.
Author unusual design shared that he took his idea from the working principle of a jet engine and used it to create a fan without blades. The operating principle of this device is figuratively called an “air multiplier”. Innovative developments have resulted in an economical, safe and stylish design.
As a result, it turns out that if a bladed fan produces vortex air currents and intermittently blows the working area, causing discomfort and draft, then a fan without blades creates a dense monotonous comfortable refreshing flow, its operation is unobtrusive, almost unnoticeable.
Comparative Advantage
These fans:
- comfortable, as they are silent and do not create vibration;
- hygienic, as they have a soft, pleasant air flow and do not create drafts, are easy to clean, and do not have parts that accumulate dust;
- convenient, as they have sufficient volume of vertical and horizontal rotation;
- stable, since the heaviest part of the device is located at its base;
- safe, as they do not have external moving parts that pose a threat in terms of household and child injuries;
- economical, despite the innovative advantages that a fan without blades has, its price is equivalent to the price of outdated bladed models;
- characterized by low energy consumption, the device uses 98% less energy compared to blade fans;
- aesthetically pleasing, as they have a modern design.
The bladeless fan is ideal for use at home and in the office. Modern design, comfortable air flow, noiselessness and absence of vibration, the possibility of remote control and the presence of a range of modes, efficiency, economy, hygiene and safety - all these characteristics are successfully combined by an innovative fan without blades. Reviews of its use eloquently state that it helps make the owner’s rest complete and his work productive.
