A fan without blades and a review of it with a demonstration of how it works. Fan without blades - an innovation in modern technology Small-sized bladeless fan for the device

Show content articles

Advanced air multipliers are gaining immense popularity in the home appliance market. Devices without blades are easy to use, highly efficient and economical. A modern device causes a lot of controversy among potential buyers with its design and functionality.

Fan without blades

The original device is gradually gaining momentum among users who are already convinced that the unit works effectively.

Fan without blades: operating principle

Based on the appearance of the device, it is not immediately possible to understand its purpose. A fairly simple design effectively transmits powerful air flow. The air moves through the air intake, followed by exit from the opposite side at high speeds. An aerodynamic device is designed to create low pressure in order to roll out air flows at the inlet. The built-in turbine is used to quickly change air masses, so the equipment is more efficient than a conventional fan.

Operating principle of a fan without blades

This type of device passes approximately 500 liters of air per second, and the supply is evenly distributed throughout the room. The creation of models was based on the operating principle of aircraft jet engines.

Healthy! Modern units do not take up much space in the room, but at the same time efficiently blow the room with a uniform air supply. They are easy to use; just read the instructions to fully understand the operating principle of the device.

Design

With the help of innovative technologies, the device is produced with various functionality. The design of different models may differ slightly, but all copies consist of the following parts:

On the body there is an engine responsible for the full operation of the device. The process of drawing in air is carried out through holes located on the base of the device.

The unit is controlled mechanically or electronically. Most models operate via remote control.

The control panel is equipped with the following functions:

1. On/off key;
2. Rheostat - provided for speed control;
3. There are additional options depending on the functionality of the device and the manufacturer.

The blowing base is made in a round, oval or any other geometric shape. This part is produced in different sizes, depending on the model of the device.

Areas of application

1. Climate control equipment is in demand due to its safety and low energy consumption. It can be used even in places where there are small children, without fear that they may get hurt;
2. The air multiplier operates using innovative technologies that allow you to create maximum comfort and the required climatic conditions;
3. Effective supply of air masses occurs evenly throughout the room, they reach even remote corners;
4. Considering the type of device, you can choose the most optimal option. Compact devices can be installed even in cars; they completely replace air conditioning;
5. Such devices operate with mechanical or electronic control. Units with a remote control are much more expensive than their mechanical counterparts, but you don’t need to get up from your seat to switch modes;
6. Almost all units, regardless of manufacturer, operate at high noise levels, which can sometimes cause discomfort. However, the rapid cooling of the apartment smooths out this disadvantage;
7. Stylish devices easily cope with the tasks, while creating a soft flow of air masses. Compared to conventional fans, they do not dry out the skin.

Watch a video about the operating principle and advantages of a bladeless fan

In this tutorial we will make a bladeless fan using PVC tubing, a plastic container and a sheet of fiberglass.

For this project, special thanks to the guys from the DYI King channel on Youtube, who were inspired to create a safe fan. But the best part about this bladeless fan is that, unlike most DIY fans, the project doesn't require 3D printing and the total cost can be less than $10.

Below in the video you can see the entire process of creating a fan.

Step 1. Tools and materials

The tools and materials needed for this project are very easy to assemble and are all pictured above. The basics for this project are a set of 6.5" and 3.5" PVC pipes, a plastic container or bowl, and a 3mm fiberglass sheet.

There is no need for a 3D printer as is used in most DIY fan projects. Moreover, we used a miter saw to make most of the cuts as it made the job more precise and easier when the same job could be done with a hand saw and some patience but would then require expensive tools to make a neat bladeless fan.

Step 2. Working principle

Unlike the name of the device, which is a fan without blades, this thing actually has a fairly high-speed blade inside the main body. You can see the operating principle of such a fan in the figure above.

In addition, a bladeless fan provides closed blade control and then airflow is directed through a closed duct body, replicating the structure of a conventional bladeless fan housing. This design offers an excellent level of protection for children.

Step 3. Making the main body

First you need to make the main body and for this you can use a PVC pipe. The main outlet is made of 6" diameter PVC pipe, which is 4" wide to form the outer air outlet casing.

To form the air pocket inside the main air outlet, we use a conical shaped bowl that fits perfectly over the 6″ PVC pipe and its collar sits on the edges of the pipe - see photo above. Cut the bowl 1" above the bottom so it forms a nice conical collar inside the main outlet casing that allows the air to rotate evenly inside the outlet cavity before leaving it.

Step 4. Inner casing and base

The internal air outlet clamp is made of PVC pipe with a diameter of 5 inches. This pipe creates a narrow opening that is almost 0.5 inches wide to distribute air evenly from the cavity/air outlet. Three parts, namely an outer 6-inch PVC pipe, a conical inner casing made of a plastic bowl, and an inner clamp made of 5-inch PVC pipe, together form the air release casing.

To form the base, use 3.5" PVC pipe cut to 5" high. To ensure that the base fits perfectly into the air outlet body, we cut one end of the base pipe in a curved shape (we cut the bend using pre-applied electrical tape), and mark the outline with 6-inch PVC pipe. The pipe is then cut using a jigsaw and then sanded down to fit the outer 6″ pipe perfectly without any gaps in between.

Step 5. Air intake hole

Before gluing the base to the main body, we drill a 3-inch diameter hole in the 6-inch PVC pipe, which will be the passage for air to enter the main body and then into the outlet hole. The hole is made using a hole saw.

The base is then glued to the outside of the air outlet using super glue. Since the base pipe is perfectly shaped to sit on top of the 6-inch PVC pipe, the superglue makes a very strong connection between the two pieces.

Step 6. Air outlet ring

The air outlet ring is made of 3mm thick fiberglass sheet, which serves as a connection between the inner half and the outer half of the main air outlet. The ring was made using a jigsaw.

Step 7. Drawing

Since most of the body parts of the bladeless fan are ready, you need to paint them so that they look neat and perfect. We paint everything white using spray paint, except for the fiberglass ring, which is protected from the paint with duct tape.

The end result is very nice and the blue fiberglass sheet looks fantastic against the pristine white background.

Step 8. LED strip

To make the design more attractive and elegant, add a 12V LED strip on the inside of the air outlet at the end where the fiberglass sheet will be glued to the inner air outlet sleeve. The light strip is cut to the required length. The tape has a sticky side and is attached by removing the protective coating from the back of the tape and then sticks to the PVC body.

When the fan turns on, the LED strip illuminates the back of the air outlet and thus produces a very cool visual effect by spreading blue light.

Step 9. Gluing all the parts

Once the paint is dry, we glue all the pieces together to form the main part of our bladeless fan, using super glue, which seems to hold everything tightly.

Step 10. Install the fan

Behind each bladeless fan is a fan with blades. So, to power our fan, we need to use a high-speed 12V DC fan, which can be taken from an old computer. More specifically, the tutorial is about a fan from a server, which is much more powerful than a regular PC fan. Therefore, we highly recommend using this type of fan.

The fan is mounted inside the base directly below the air outlet housing using four wood screws to hold the fan securely in place. The fan is installed in such a way that it pushes air upward and thus we need the fan to be quite stable.

Step 11: Air Intake

A pair of air intakes are located just below the server fan on both sides of the base pipe, i.e. base pipes. These intake holes allow air to be drawn into the base.

To prevent someone from accidentally injuring their fingers by inserting them into the base of the fan, we glue a metal mesh on both holes. The mesh is first painted matte black and then glued inside the base using hot glue.

In this publication, we will look at a device called Dyson’s Air Multiplier and, despite its unusual appearance, it is a fan that has an obvious feature - it does not have the usual blades, which, when rotating, create a flow of air directly directed at the object. In the video there is a review of it and a demonstration of how it works. This is an invention of Dyson, which specializes in the development and assembly of vacuum cleaners. The company's employees decided to create a bladeless fan, based on the principles on which their favorite creations, the vacuum cleaners mentioned above, operate.

Despite the apparent sensationalism of this useful model, the inventors were unable to completely abandon the blades. They remain in this device, but are hidden in the body, in general, like in a vacuum cleaner. The beautiful ring contains properly directed slits, and at the base of the fan there are blades that force air upward.

The nice utility of this thing is not only the futuristic design, but also the safety of the design, which has no external rotating parts. For owners of apartments and other premises where children are located, this is an important advantage. In addition, the air flow of a bladeless fan is more uniform than its standard counterpart. The disadvantage is a hum, reminiscent of the noise of a working vacuum cleaner, a weaker flow than in the paddle counterpart, and a high price. Figuratively speaking, the wind costs 450 rubles, and the cost is several times higher.

The main disadvantage is noise.

Discussion

And if you make a super coil in this ring, and a transformer at the bottom, then by accelerating the electrons by 4000 volts and creating a powerful twisting magnetic field, you can create the same effect. Electrons from the magnetic field will accelerate air particles. And there won’t be as much noise if it can be heard at all outside of the flow.
This is called induction. It will only be 15 times more expensive.

It's buzzing, I think the efficiency is several times lower compared to normal fans, problems with maintenance, dust and all that. useless thing. As for safety, it seems that all fans are equipped with mesh protection. Is not it so?

It makes noise. There is a 100% impeller like that of a vacuum cleaner, just for pressure to pump this ring. Dyson or whoever invented it, handsome, hid the valve in a separate housing (he took the housing from a vacuum cleaner) and simply added a more original air duct to it. That's it, the know-how is ready. It was correctly written above, a product for a variety of “on the couch” stores. A cheap Chinese floor fan operates almost silently at speed 1 and moves 50 times more air through it.

Useless thing. Well, you can wash this ring under the tap, but the dust inside won’t be sucked in? A regular fan equipped with a mesh is also safe. This fan is quite loud. I don’t see any advantages in it at all.

Damn...4500...7500 rpm is brutal, it will sound like an airplane. But thanks for the video! Otherwise, in the descriptions in online stores, some kind of garbage is written, you won’t understand anything from them, but now at least I looked - I understand.
I'll buy it when they start making silent ones and at a normal price. 1500 rpm should be the maximum. Better - 600. In principle, everything is clear: there must be a thicker column in order to fit a fan that provides the required air flow at low speeds.
So, producers, get to work!

I've seen completely silent specimens. When I came across a stream of air coming from nowhere, I was very impressed. Imagine standing in front of an incomprehensible device that shows no signs of active operation, but at the same time generates a pleasant flow of air. I was immediately delighted. Returning home, I began surfing the Internet to understand what it was and how it worked. I remember then I immediately thought that Mr. Dyson had practically created a fundamentally new type of propulsion system, which was based on the principle of air flow multiplication. And that uniform air flow, without turbulence, is very useful for such types of transport as Hoverbike, etc.

Alas, it is not an ideal fan, as it makes noise; an ideal fan should be absolutely silent. But this is a contradiction, cutting the air with blades creates a beneficial effect (air flow) and at the same time a harmful effect (noise), which means the blades must spin to create air flow and should not spin so as not to create noise. This is a physical contradiction, who will resolve this contradiction , will create the perfect fan.

Well, it’s not easy to wash it, but on the contrary, it’s very difficult. The fan is hidden in the case, and it’s not easy to reach it to remove the dust piles. There will be even more dust there than in the computer's system unit. And that's all show-off. Efficiency drops when air has to be pushed through it all before it comes out. It will either be weaker than a regular fan or louder.

Try falling asleep with a food processor running in your room. After all, the fan is a blade fan, the blades are just hidden. Low-speed fans with large blades are more practical, quieter and no less safe.

Recently, advertisements for a safe bladeless fan periodically appear on the RuNet; we suggest considering the design of this climate control device for the home and the principle of its operation. We will also talk about the strengths and weaknesses of this device and the main characteristics. After which we will conduct a brief review of several models of bladeless fans, and at the end of the article we will consider the possibility of creating such an unusual device with your own hands.

Design and principle of operation

In 2009, J. Dyson presented to the world his own fan development. The design feature was the absence of blades, which, however, did not prevent the device from creating a stable air flow. Moreover, the volume of air at the outlet exceeded that entering the turbine by one or two orders of magnitude. Do you think it's magic? No, everything is much more serious - aerodynamics.

It's all about the profile of the ring; it is given a special shape.

Thanks to this, the air escaping from the holes is focused so that a low-pressure zone is formed in front of the ring (highlighted by a red oval in Fig. 3).

Since such an area is surrounded in front and on the sides by increased pressure, air is drawn in from the back of the ring, forming a steady directed flow.

Note that it took Dyson about four years to compile a mathematical model of the profile that would allow achieving maximum effect and finalizing the technology. Most Chinese analogues of its device cannot produce even half the power of the original device. The inventor patented the design, in particular, the profile of the ring and the structure of the turbine that pumps air, so in order to make full-fledged copies it is necessary to purchase production rights from the author.

How does the fan work?

Since the drawing of the device is protected by copyright, we will talk about the operation of the fan, based on the drawings used in the advertising of this product.

Explanation of the picture:

• A – holes for air supply to the turbine.
• B – turbine engine.
• C – air flows inside the ring.
• D – ring.

When turned on, the turbine begins to force air into the ring, from where it exits under pressure into a small slot (A in Fig. 5) or small nozzles.

Some models (for example, Flextron FB1009, KITFORT KT-401, HJ-007, Bork) have a built-in motor (B in Fig. 5), which allows you to change the direction of the ring, and, consequently, the air flow. Some manufacturers have provided the possibility of installing a special aerosol into the design; as a result, Airmultiplier Dyson (that’s what Dyson called his brainchild) additionally acts as an air freshener (part of the Kitfort, Supra, Renova, Vesson model range).

There are bladeless fans with air cooling and heating; such household appliances can be classified as full-fledged climate control equipment.

Original devices are produced with a power plant (turbine) with a power of 25 or 40 W. For Chinese analogues, this parameter can vary over a wide range. Such a small power is quite enough for up to 500 liters of air per second to pass through the ring (again, this value applies to original products).

Advantages and disadvantages

Having examined the structure of air multipliers, we can move on to analyzing their advantages and disadvantages. Let's start with the first one. Advantages:

Unfortunately, this device also has disadvantages that significantly affect consumer demand:

1. The high cost of original models, it can reach up to 20 thousand rubles or more, which is comparable to the purchase and installation of an inexpensive split system. However, you can put up with this price if the bladeless fan has the functions of heating and cooling the air. Note that Chinese analogues are significantly cheaper, some even by an order of magnitude, but, as already described above, they are less efficient.
2. Despite the fact that the fan power plant is low-noise, during operation this device emits a characteristic hum, reminiscent of the operation of an aircraft turbine. Moreover, at maximum power the noise level can reach 60 decibels, which is quite a lot, since an hour is enough for it to give you a headache. True, in this mode the device creates such a strong air flow that discomfort occurs, so the maximum level of operation is practically not used. In normal mode, the device makes much less noise.
3. The 15-fold increase in flow stated in the advertisement is technically correct, but there is a certain nuance. This value is typical for the maximum mode, which is practically not used.

Review of models on the market

Let us give as an example several models of devices available on the Russian market.

Bladeless Fan, a small, inexpensive bladeless desk fan. Made in China. The cost is about $40-$50. A minimum of functions and low power (12 W) allow you to obtain an air flow that is quite acceptable for desktop devices.

Another budget option with a minimal functional set is Fan Leader, which, according to suppliers, is made in Poland. Also in a desktop version, in the same price range, but slightly higher power - 35 W. A characteristic feature is that the working area is made in the shape of an oval. Note that this form is found in many models, for example, Orion OR-DSO2.

Well, for comparison, let’s look at the original design - the Dayson Hot + Cool model. This device is available in a floor-standing version. It has an air heating function. Turbine power is 40 W, in heater mode – 2 kW. There is a remote control, an information board indicating the selected mode and the set temperature. For all this pleasure you will need to pay about 500 – 540 dollars.

Concluding the topic of the review, we present a comparative table of the Dynson model range and the Chinese analogue Unico ION.

Is it possible to make a bladeless fan with your own hands?

There are several videos on the RuNet dedicated to this topic, where various materials are used to create a ring, from plastic buckets to PVC sewer pipes. Power plants are also varied, mostly powerful processor coolers, but there are originals that use a vacuum cleaner engine. The effectiveness of such structures and their characteristics are highly questionable, especially since no measurements are provided.

As you remember, to create a low pressure zone it is necessary to focus the air flows in a special way. Using ordinary materials at hand, this is quite difficult to do, and work for the sake of work does not carry any rational meaning.

One of the new products on the climate equipment market is a bladeless fan. The device simultaneously arouses interest and doubt among potential buyers. This unusual bladeless fan surprises with its 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, the patents for which were sold to different countries around the world.

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 – a ceiling version of a 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.

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

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.

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 output 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 of such efficient operation of a bladeless fan is the multiple multiplication of drawn-in air at the outlet. This occurs due to the special shape of the blower and the presence of a specially shaped hollow channel inside it.

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.

Manufacturers indicate the noise level of a specific model in the 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 the air passing through the 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 make the device, use a plastic container, a simple fan and a glue gun.

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

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 with a 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 to put the PVC pipe on one of the tee pipes and mark the boundary - this will be a segment of about 10 cm that needs to be cut.

Place the cut piece into this 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 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 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 by placing a piece of cotton wool with 5-7 drops of essential oil, you can fill the entire 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 scheme of a finished factory-produced product.

Let’s start building a homemade product useful in everyday life with the body:

Image gallery

To manufacture it, three pieces of plastic pipe of different diameters were required, a 12 V fan, a toggle switch with connection devices, capacitors, resistors, an NE555 integrated circuit, a Schnittke diode, diodes, a power supply and consumables

The largest ring is cut from a 6″ pipe, its height is 10 cm. We cut the same piece from a 5″ pipe, in the photo it is blue. For the stand, cut 13 cm from the 3.5″ pipe. You also need to find a 6″ container, from which we cut out the bottom

We cut a narrow piece of pipe prepared for the rack to fit a large six-inch ring. To do this, first try on the parts and outline the necessary lines

Cut a hole in the large ring with a diameter approximately 2 cm smaller than the diameter of the stand

Place the hole in the large ring directly above the stand and glue it

We strengthen the connection with tape or glue it with mesh adhesive mounting tape. When viewed from the side of the rack, a ring-shaped area should form inside the structure

We glue the fiberglass piece to the five-inch ring. The size of this part should cover the difference between the outer and inner ring

We spray paint the inner ring with the glued part white. Glue the LED strip from the inside to the outer edge of the large ring and assemble the housing

Step 1: Purchasing materials for homemade crafts

Step 2: Cutting the body blanks

Step 3: Trimming the stand to install the ring

Step 4: Trimming the stand to install the ring

Step 5: Gluing the Post to the Large Ring

Step 6: Reinforce the connection with tape or masking tape

Step 7: Fiberglass the 5-inch ring

Step 8: Installing the LED Strip Between the Rings

The case is ready, now it should be equipped with technical stuffing:

Image gallery

We place the fan in the rack, solder the wires to it, and fix the device parts
