What is the meaning of the silent option
It is no secret to anyone that even the most “quiet” air exchange units produce a certain amount of noise during operation. If speak about minimum values sound, then the average is at the level of 35 dB. To the human ear, this is analogous to a whisper. However, even such Appliances Prolonged exposure causes irritation.
If you install a silent fan instead of a conventional one, you can provide a comfortable environment for the human ear. The volume of such devices is 20-25 dB, which is commensurate with a very quiet whisper. At a distance of 1.5 m from the operating unit, the movement of the blades is almost indistinguishable.
The dependence of noise on the operating mode and performance of the device
How a silent fan works
Silent type devices work at times quiet their counterparts for a number of reasons, the main of which is design features. The device consists of 3 main functional elements, thanks to which it is possible to reduce the sound effect to a comfortable 25 dB.
Structurally, the device consists of:
For the formation general idea about how exhaust propellers are arranged and work, you should consider their device in more detail.
electric motor. Silent devices are equipped with the same motors as traditional devices. The differences come down primarily to the method of fixation. Reliable fastening minimizes vibration noise. In fairness, it should be noted that poor-quality fastening of an electrical appliance is fraught with vibrations.
electric motor
Device body. In most cases, the case design is quite flimsy. Thin walls contribute to the occurrence of vibrations, accompanied unpleasant sounds. As for the silent unit, it boasts a solid and one-piece design (subject to selection quality product). Thanks to this approach, it is possible to cope with any vibrations.
The smooth operation of each part of the electric motor is ensured by high-quality bearings. In conventional units, ordinary solutions are used.
note! Special attention they also give lubrication, thanks to which any noise and rattle are leveled. This consistency extends the life of the device at times.
Modern silent duct fans are characterized by impeccable quality execution. The finished product goes through several stages of testing before it goes on sale. And if the standard of the sound range is not observed, then the fan does not pass the test. Significant noise can also occur if the unit is not properly balanced.
What are the types of silent fans
Household exhaust devices can be completely different in design. Each device is designed for specific operating conditions. household models devices can be divided into 4 types:
ducted. Placed at the base of the duct. There are no rubber elements in the case, which is the main reason for additional vibrations and noise during operation. However, they are much more efficient than conventional fans.

What parameters and functions of the fan to pay attention to
Before buying a device for the hood, you must carefully study it specifications take into account a number of important parameters.
Advice! When choosing a quiet fan, preference should be given to units with indicators 15% higher than the required, calculated ones.
Models automatic devices can be equipped with an integrated humidity sensor, which is extremely convenient. The cost of axial products is higher than standard ones, at the same time, the efficiency of such devices is unrivaled. Experts advise using devices with an IP34 protection class.
Choosing a fan for the bathroom in the apartment
Before starting installation work, make sure that the ventilation in the room is working properly. About that, we already wrote earlier. Next stage– choose the most suitable place for installing the fan. Experts recommend mounting an exhaust propeller under the ceiling, since, according to the laws of physics, it is up and hot air masses rise.
Advice! When choosing a device, the installation location must also be taken into account, since not all models can equally well be placed at an angle, horizontally, or in an existing vent.
Procedure:
1. We insert the fan into the hole in the wall, and if the hole is much larger than the size of the duct, then we need polyurethane foam to close the voids around the duct.
2. If the fan needs to be replaced for any reason, it is rather problematic to get it after fixing it with foam, therefore, it is recommended to purchase and fix a piece of plastic pipe to fit the size of the air duct. And then insert the fan itself into the fixed and plastered plastic pipe. Thus, if necessary, the fan can be easily dismantled.
Do not forget to bring out the wiring to connect the device.
3. If, after you insert the fan into the pipe, it dangles, then you can put a pair of rubber bands on it to seal it. With their help, the device will not only sit tighter, but vibrations will also decrease. At this method you can avoid fastening with self-tapping screws, that is, you do not have to drill the wall. But if you still don't like it this option, then you can resort to fastening with self-tapping screws.

Ventilation is installed for exhaust in apartment buildings or private houses. And although she does her job, you want to quickly remove moisture from the bathroom or bad smell from the bathroom. What about steam or the smell of burnt meat in the kitchen? You can install a fan on an exhaust grill, but even quiet devices make noise that is annoying at first, and then completely leads to headaches. The output will be silent duct fans for the hood. Today we will look at their main technical specifications, and also figure out how they are mounted.
Read in the article:
Where are silent inline exhaust fans used?
Such ventilation devices are used not only to provide exhaust from the kitchen or bathroom. They are used in industrial workshops, in rooms with high dust content, emergency systems smoke removal. Industrial exhaust fans are more powerful and larger. But today we will talk about household supply and exhaust devices mounted on separate rooms or on the entire ventilation system of a private house.
Duct fans for exhaust: types, features, differences
There are three types of exhaust fans that differ in design:
- Axial– the engine is in the center of the cylinder. It rotates the impeller, which moves the air flow along the axis. Such devices are easy to install (often installed on a kitchen or bathroom hood) and provide good air exchange - about 100 m³ / h. Among the shortcomings, we note the presence of noise of about 30 ÷ 50 dB.
- Radial or centrifugal exhaust fan– these types of devices are similar. An impeller is installed in the housing, the blades of which are located not across, but along the channel. When the wheel rotates, a centrifugal force is created, sucking or forcing air masses into the room. The power and performance of such devices is higher. They are capable of pumping up to 15 m³/min. If an axial fan is installed in only one room, then a powerful centrifugal or radial fan will ensure the exhaust of the entire private house.
Useful information! If from the ventilating device to exhaust opening more than two meters, an axial fan will not be able to provide air exchange. Only centrifugal or radial.
How an exhaust duct fan works: a schematic diagram
Silent duct fan consists of four main parts:
- an impeller that moves air masses;
- an electric motor that rotates it;
- a housing in which an impeller with an electric motor is placed;
- bearings - provide soft, silent rotation.
High-quality bearings - the key to long-term operation of the ventilation device In addition to bearings, noiselessness is ensured by precise balancing at the factory. Manufacturer tests finished goods. If the noise is exceeded, the device is rejected, in retail network does not arrive.
Expert opinion
HVAC design engineer (heating, ventilation and air conditioning) LLC "ASP North-West"
Ask a specialist“The designation “silent” is not quite right. It will not work to reduce the sound of a running engine to 0 dB. Such devices emit noise up to 25 dB, inaudible to the human ear.”
The electric motors of such devices are no different from conventional ones. Noiselessness of work is reached by reliable fixing. If you purchase a fake (fake), the mount will loosen over time, which will lead to an increase in vibration and, as a result, an increase in noise.
Lubrication in bearings also plays a role. If cheap grease is used, it will quickly work out. This will lead first to an increase in noise, and then to wear of the balls and seats.
Technical characteristics of devices for ventilation
When choosing a device for extracting into a ventilation duct, you should pay attention to some parameters.
| Characteristic | Description |
|---|---|
| Noise level | During operation, the devices make noise. Here, this parameter should not exceed 25 dB. If the case is covered with sound-absorbing material, the noise figure will decrease. |
| Electrical protection class (IP) | The higher this indicator (the protection class is indicated on the packaging and in the technical documentation), the more aggressive the environment in which it is possible to use the device. |
| Amount of pumped air (capacity) | The parameter depends on the number of people living or the purpose of the room. For an accurate calculation, the total volume of the room (rooms) is multiplied by the multiplier: · for ordinary rooms with three residents - 3; for bathrooms - 6; for bathrooms - 10. |
| Availability of additional functions | Turning on the device can be done not only in manual mode. These can be light, motion or humidity sensors. |
Useful information! Despite the role played by the cost of equipment, it is worth paying more attention to technical characteristics. Even a small amount spent on an unsuitable appliance is money wasted in literally the words.
Geometric parameters and dimensions of duct fans for exhaust
The shape of such devices are round, rectangular or square. The choice will depend on the shape of the ventilation duct. After all, it is clear that it is problematic to install a duct fan for a round duct into a square one, and it is completely impossible to install a square device into a pipe.
The sizes of such devices are different. Common ones include:
- duct fans 200 mm;
- exhaust fans 100 mm;
- duct fans 125 mm.
Such dimensions are not accidental - they coincide with the dimensions of the ventilation shafts apartment buildings and boxes produced in Russia.
Selection criteria for silent duct fans for exhaust
When choosing such equipment, you should pay attention to the quality of the product. The edges should be smooth, without scuffs and sags. Do not hesitate to ask the seller about the quality of the goods, whether there were returns. Need to study carefully technical documentation and a certificate of conformity.
Useful advice! Demand to fill out the warranty card in front of your eyes. The store is obliged to put its stamp on it with you. If it is already affixed, it is possible that this ventilation unit was sold but returned for some reason.
Silent exhaust fans in the bathroom, in the kitchen or in all rooms, you need to check when buying. Ask a consultant to turn on the device in the network with you. This way you can be sure that the product is working. After all, giving it away later on warranty repair you can wait a long time for a return, which means that the installation of the ventilation system will stop.
Pay attention to the body of the device. It should not have chips, cracks, scratches or dents. The packaging must not be damaged.
Equipping silent duct fans for exhaust: basic and additional functions
The main function of the ventilation device is to remove moisture, unpleasant odors or to bring fresh air into the room. For this reason, it is worth paying attention to power and performance. These parameters determine how well the device will perform the work.
But in addition to the main functions, you should not lose sight of the additional ones. Housewives are faced with the fact that from air vent smells from neighbors get into the apartment. When the fan is on, this is not possible, but what if it is off? For such cases, an exhaust fan is installed with check valve, which blocks the air flow, opening only to the hood.
Convenient exhaust fan for the kitchen, equipped with a humidity and temperature sensor, which turns on only when necessary, which saves energy. The reverse function will also be useful. These quiet hoods for kitchens, bathrooms or all rooms can be switched to fresh air mode.

Rules for installing a silent exhaust fan
Duct ventilation devices are mounted in the gap of the duct. For installation, a part of the ventilation duct is removed according to the size of the device. The fan is dismantled, diffusers located on both sides are removed from it, which are fastened with clamps or rubber couplings to the air duct. After that, a fan is mounted in the remaining gap.
Connecting a silent duct fan to a 220 V network varies depending on the number of speeds. If there are 2 contacts in the terminal box, then everything is clear - zero and phase (one speed). But three contacts speak of a two-speed device with two impellers. In this case, the neutral wire goes to the “N” terminal, and the “L1” and “L2” contacts are separated by speeds. You need to decide what speed of rotation of the blades you need. "L1" is the maximum speed, and "L2" is the minimum, which is 60% of "L1".
Maintenance of silent duct fans during operation
If you properly and timely maintain the equipment, it will last much longer. More often than other nodes clogged ventilation grille. When it is clogged, it becomes difficult for the engine to turn the blades, under load it heats up, the winding burns out. The blades also require periodic cleaning. Sometimes, to clean the impeller, the fan has to be dismantled. However, it is better to spend some time and effort on cleaning than to subsequently acquire a new one. ventilation device instead of burned out.
The air duct itself also requires cleaning - fat settles on the walls, to which dust sticks. It is not always possible to clean such dirt with a vacuum cleaner. The joints of ventilation ducts are especially vulnerable. If cleaning is not done in time, dust and grease clumps come off the walls and fall into the fan blades. This leads to jamming and failure of the device.
Is it possible to repair a duct fan with your own hands
If the electric motor fails, it will not work to rewind the stator or rotor winding on its own. Having determined this malfunction with a multimeter, the home master has to rewrite the device data and go to the electrical store in the hope of finding suitable spare parts. There is another option - online stores where you can find everything. We'll have to wait a while until they send the right one, but this purchase will cost less. The same applies to worn out bearings or a broken impeller.
Wiring faults can be fixed quickly, but basic wiring skills are required.
Very important! If a wiring fault is detected, the voltage should be removed by turning off the introductory machine, and only then proceed with the repair. Remember defeat electric shock life threatening!
If there is the slightest doubt that House master will be able to fix the problem on their own, it is better to seek help from professionals. After all, no self-respecting master will undertake the repair of equipment that has been dismantled before by another person.
Brief overview of manufacturers, models and prices
On the Russian shelves there are many models of various manufacturers. In order not to burden the reader with unnecessary information, we will consider only some of them, mentioning the technical characteristics and cost, as of January 2018.

The Spanish company Soler&Palau continued its permanent job on noise reduction in fans presents a novelty: a unique duct fan TD-SILENT.
Problem advanced level noise in places of permanent residence of people is especially relevant in modern world. The requirements for comfort in these premises are growing, the requirements are becoming more stringent normative documentation. Ventilation systems, along with providing fresh air and indoor comfort, contribute to our lives and their part of the noise.
At the stage of modeling a new fan, the developers were faced with difficult tasks, because it was necessary to achieve unprecedentedly low parameters in terms of noise level and surpass the TD-MIXVENT series fans. Soler&Palau engineers solved this problem. Thanks to the use of a fundamentally new fan layout and high-quality materials, the noise level of TD-SILENT is lower than that of the closest analogues by 12 dB(A).
The heart of the fan is an impeller with diagonal blades and an electric motor located in a special casing. To significantly reduce the noise level, the designers created a double housing with a layer of special noise-absorbing material. Inner, perforated casing lets through sound waves, directing them at a certain angle to a layer of noise-absorbing material, in which sound waves are damped by almost 100%. The transmission of vibrations from the fan housing to the air duct is prevented by special quick-release clamps with rubber seals. TD-SILENT fans are made of high quality plastic. For ease of installation and maintenance, the fan is made of two parts: a mounting bracket and a fan housing attached to it.
The housing can be installed in any position relative to the fan axis, which, together with the rotating terminal box, makes connecting the fan to the power supply network quick and convenient.
The model range of TD-SILENT fans consists of five standard sizes, with connecting diameters from 100 to 200 and air flow from 180 to 1100 m3/h. Factory warranty for TD-SILENT series fans is 5 years.
Shop "Lyuchki.RF" offers silent household fans for extract from the Spanish company Soler & Palau. These are reliable models with a wide variety of characteristics, easy to install and operate.
Productive and quiet
It is believed that the more powerful the ventilation, the more it will make noise. In general, this is true.However, household low-noise fans are designed to provide air exchange in sufficient small spaces. They do not need such a high level of power as, say, for production shops.
So you don't have to choose between efficiency and personal comfort.
Silent exhaust fan
"Pull out" the air, eliminating with it unpleasant odors and excess moisture, reduces the risk of mold and prolongs the durability of the interior.At the same time, to ensure an optimal microclimate, it will be necessary to take care of the influx of fresh air and occasionally ventilate the room.
Silent supply fans
They act according to the strictly opposite principle - they “drive” fresh air into the kitchen, eliminate stuffiness, and contribute to the accelerated settling of steam and smoke.However, they require an additional device to eliminate the "exhaust" air. Since the layout and architecture of the room itself does not always allow for the full circulation of air flows only due to the supply system.
How to choose?
The optimal characteristics of the model depend on many parameters, including the area and operating conditions of the room.In the Luchki.RF store you can purchase a silent overhead fan with any:
- diameter
- performance
- power
- color
- design
- additional options(timer, humidity sensor, etc.)
