A few words about creating a fanless fan

Model, radically different in its appearance from others

types of fans, familiar to many since childhood, was invented in 2009. Its creator is James Dyson.

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

Bladeless models allow you to relax

Bladeless models allow you to relax, enjoy the coolness and not worry that someone from pets or children will suffer, hitting the fan blade

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

About 4 years the leading engineers of the company J. Dyson spent on it to simulate the ring of the fan, which can most effectively pass through the air, multiplying it many times.

The bladeless device from Dyson already in 2010 was sold in the homeland of the inventor for 199 British pounds. This price can hardly be called popular, but there were a lot of people who wanted to get an innovative fan.

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

Ceiling bezlopastnogo version of the fan

In the near future, users will be able to try out a new product - a ceiling version of a bladeless fan. This is Exhale Fans equipment developed by Nick Heiner.

Device and operation of the flawless device

A fan without blades is often called in honor of its creator a Dyson fan or, as he himself called the device, an Air Multiplier multiplier. This original invention is in demand due to the ability to create a uniform flow of air and fit perfectly into any interior.

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

Constructive components of the air multiplier

The air multiplier from Dyson can multiply the air flow at the outlet. Moreover, the engineers, designers and technologists of the company create more sophisticated models that can not only blow objects, furniture and people in the room, but also perform functions air cleaning and humidification.

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

Bladeless Fan Models

Different manufacturers offer their fans without blades, different build quality, noise, features and cost

Depending on the model, the device itself will be different. After all, the more functions it can perform, the more buttons will be on the control panel.

The fan without blades consists of the following parts:

  • housing;
  • Control Panel;
  • blower.

In the case is the engine 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.

Appearance of a bladeless fan

The appearance of the device for all manufacturers may vary 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 different manufacturers are equipped with remote control, working, on average, at a distance of 3 meters.

On the control panel are provided:

  • on / off button;
  • rheostat to adjust the speed of work;
  • other buttons depending on the multiplier model and functions provided by the manufacturer.

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

The fanciful shape of the flawless fan

The fanciful shape of a fanless fan will allow it to be not only a useful device in the room, but also to become an original element of the decor.

Air multipliers by the method of installation can be divided into 3 types:

  • floor standing;
  • desktop;
  • wall mounted.

The first 2 types belong to portable devices, and the last - to stationary ones. Often, manufacturers provide for one model 2 options: mounting on the wall and installing on the table. In this case, the fan is necessarily equipped with brackets with dowels.

Complete set of the fanless fan

It is important when hanging the device on the wall to use the components proposed by the manufacturer. Otherwise, you can lose the warranty.

Dyson fan: principle of operation

Bladeless fans are able to pass through up to 500 liters of air in 1 second. The output stream is evenly distributed, gently enveloping the entire space. When visually inspecting moving parts outside the working device is not observed. That is, at first glance, looks like an air multiplier.

The principle of such an efficient operation of a fanless fan is the multiple multiplication of the drawn air at the outlet. This is due to the special shape of the blower and the presence of a hollow channel of a special shape inside it.

The shape of the air channel of the fan

The shape of the air channel of the fan on one side is half wider than on the other. This allows the air to significantly increase the speed when driving on it.

First, a high-speed engine pulls air through the small holes at the base of the device. Then this air moves to the blower duct. The canal shape is constructed on the same principle as the aircraft wing. Therefore, when the air moves inside the channel, its velocity increases.

Special air channel shape

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

From the channel, the air exits from the narrower side, and from the back, a low pressure area is formed. This ensures active air intake, the volume of which is 15–20 times greater than the initial one drawn in by the engine.

As a result, people in the zone of the device blows much more strongly than when using a conventional fan blade.

Features of using the multiplier

The sphere of use of a fan without blades is very wide - it is a house, office, cottage, kindergarten, hospital or other municipal institution. The exceptions are bathroomsrooms with a pool, saunas, baths. There it is important to ensure effective removal of wet vapor.

The fact is that the device is safe if it will be used by capable members of society. Otherwise, the use is allowed under the supervision of adults.

The device copes with the functions

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

In addition to the soft distribution of multiply increased airflow, a fan without blades can humidify the air and cool / warm it. The user sets the percentage of humidity in the settings. The adjustment range depends on the model of the device and varies, on average, from 30 to 70%.

As for the function of heating or cooling, 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, smoke or chad.

Bladeless Fan with Remote

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

The market for HVAC equipment is replete with offers of different models of flawless fans from many manufacturers. Among them are both affordable models worth up to $ 100, as well as expensive versions of well-known brands with the functions of the present air conditioner or split system.

Among the manufacturers offering their bezlopastnoe equipment, we can note the following companies: Flextron, SUPRA (Supra), UNISVET, Clever and clean, Roward, Dyson, Coolguy, Aaron, RENOVA, Orion, Bladeless, BiLux, MAGNIT.

The price range of these companies are free from devices from 2,000 to 35,000 rubles and 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 and more. This is the most important parameter that should be taken into account before purchasing.

fan noise less than 60 dB

When the fan noise is 60 dB and higher, a person will have fatigue after an hour of work and his head may ache

The noise level of a particular model manufacturers indicate in the specifications. Moreover, this is the ultimate level that is achieved when the equipment operates at maximum speed. In cheap devices, the stated noise level may not be true.

Pros and cons of flawless fans

The air multiplier has its advantages and disadvantages identified by users.

Among the positive aspects can be noted:

  • security;
  • uniform air flow;
  • minimum electricity consumption;
  • convenient management;
  • 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 whole structure turned out to be stable.

The special shape of the ring blower

The special shape of the ring blower allows the fan to gently and evenly distribute air flow throughout the entire room.

Power consumption is most often 25 watts and 40 watts. Models with other characteristics are less common.

Control of the device is simple and straightforward. All the subtleties of adjustment of the acquired model are described in detail in the instructions. The air flow from the fanless fan is also adjustable.

Bladeless fan adjustment

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 flawless device has its drawbacks:

  • Sound 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 loses according to this indicator to habitual blade fans.
  • Structural fragility. This disadvantage is characteristic of inexpensive Chinese-made counterparts.

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

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

Aromatization and ionization of air flow

Aromatization and ionization of air flow so far exists only in expensive models of the latest generation

Bladeless device with their own hands

The question of creating a fan without blades with their own hands was attended by many craftsmen. During the experiments, home craftsmen produced a lot of working homemade products.

Option # 1: plastic bucket products

For the manufacture of the device using plastic packaging, a simple fan and glue gun.

Materials for homemade

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 of 5 and 10 liters;
  • PVC pipe 110;
  • distribution tee;
  • stub.

First you need to cut a piece of 15 cm from the pipe. Then, in a 10-liter bucket, make a hole in the side that is strictly the same size as the outside diameter of the pipe.

Connection of two parts

Using the glue gun should be carefully and carefully connect these 2 parts together

The next step is to take a 5-liter bucket and cut off 3 cm from the top edge. Still have to cut a hole in the bottom, the diameter of which is 2 cm smaller 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 the case with the engine, the role of which will be performed by an axial fan. To do this, put a cap on the side branch of the tee, causing a pre-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 tee nozzles and mark the border - this will be a segment of about 10 cm, which is to be cut off.

Through hole

Place the cut-off part into this nozzle and make a through hole 5 cm long from the edge.

It is here that an axial electric fan of the required diameter is to be placed, and in the hole - to lead the wire for inclusion in the electrical network.

To make the finished homemade aesthetic appearance all the details can be painted in one color with spray enamel. For example, in white, beige or blue. The chassis is ready to connect to the network.

Homemade Bladeless Fan

It remains to place on top a homemade blower from 2 buckets and turn on the fan

If you put a container with ice inside the case, then the homemade will act as an air conditioner. And when placing a piece of cotton with 5-7 drops of essential oil, you can fill the whole room with a pleasant aroma.

Option # 2: plastic pipe fan

The prototype of the second option was a bezlopastnoy device brand Dyson. The hull and the technical part is assembled by a home craftsman according to the factory-made finished product scheme.

The construction of home-made useful home-made things start with the hull:

Step 5: Gluing the rack to the big ring

Place a hole in a large ring right above the stand, glue it

Step 6: Strengthen the connection with scotch tape or masking tape.

Strengthen the connection with adhesive tape or taped with a mesh adhesive tape. When viewed from the side of the rack, a ring-shaped platform should form inside the structure.

Step 7: Five-inch ring pasted over with fiberglass

Glue the fiberglass part to the five-inch ring. The size of this part must cover the difference between the outer and the inner ring.

Step 8: Installing the LED strip between the rings

The inner ring with the glued part is painted from the spray gun in white. Glue the LED strip from the inside to the outer edge of the large ring and assemble the body

Step 10: Cutting the two holes in the rack

In the rack, cut two holes of equal diameter. Holes should be placed strictly opposite each other

Step 11: Installing the Fan in the Chassis

Scrape holes to remove any burrs. We put in the rack the fan, which should rest against the ring-shaped platform

Step 12: Pasting the holes with plastic mesh

Cut out two plastic circles from a plastic mesh, the diameter of which will be 1.5 cm larger than the holes. Glue the mesh inside with a glue gun

Step 13: A set of technical equipment to the control board

Control board, resistors with capacitors and a Schottky sensor, as well as diodes with an integrated circuit need to be purchased

Step 14: Install the toggle switch at a convenient point

Choose a convenient place for the toggle switch and install it, pre-drill a suitable hole

Step 15: The internal fixing wires of the device

We try not to leave too long wires inside the drains. And all that is possible, we attach the glue gun to the pipe walls

Original ideas for creating a domestic fan are presented in this article.

Care and maintenance of the device

A fan without blades is able to serve the time stated by the manufacturer in the instructions only if the rules for its operation are observed. 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 work.

If you need to rearrange the equipment, then it should be taken behind the body, and not the blower.

To maintain the air multiplier, it is sufficient to periodically perform the following actions:

  • clean the blower holes with a brush to prevent clogging;
  • wipe the blower and the device body with a damp cloth, removing dust and other contaminants.

Maintenance should be carried out as needed. It is not necessary to use special cleaning agents or detergents - the surface of flapless fans is well cleaned with a wet or dry soft cloth.

Operational safety measures

When operating the device, one should not forget about safety measures and in no case use it in case of breakage.

If a malfunction has been detected, then you should contact the specialists authorized to repair the climatic equipment of a particular manufacturer.

Attempting to fix the damage yourself may result in loss of fan warranty. In case of lack of experience in repairing such devices, you can cause even more damage to equipment.
