An exhaust fan for a toilet is a must-have element nowadays, because with its help the room maintains optimal humidity and removes unpleasant odors. But for the system to work effectively, you need, firstly, to select equipment with optimal parameters, and secondly, to install it correctly. It is these aspects that I will talk about in this review.
Features of selection and installation
Let's figure out how to choose a high-quality and reliable product and how to connect it to ensure maximum operational safety and operational efficiency. Each factor is very important, so please read this section carefully.
What to look for when purchasing
If you carry out all the work yourself, you will have to understand the design features of the equipment in order to choose the best option. I do not recommend relying on the advice of sellers for the following reasons: often their knowledge is limited to the store’s assortment, they often try to sell stale goods or options that are unreasonably expensive.
First of all, I will talk about the types of construction, there are only two of them:
- Axial fans- the most common type of product in our time, inside the housing there is a working unit on bearings, which, due to the rotation of the blades, removes air from the room. The main plus is low price, the main disadvantage is that the performance indicators decrease in proportion to the resistance, that is, if you live on the lower floors of a high-rise building, then the actual efficiency will be no more than 10% of the declared one;
- Centrifugal options differ in design; instead of a conventional propeller, air is removed using a wheel with blades. The actual performance is 2-3 times lower than that of the first type, but power losses due to resistance are minimal. Such a fan will be effective even on the first floor of a twelve-story building, so if you need equipment for your apartment, then I advise everyone to pay attention to this group of products.
The question of which fan to install is best decided during the repair work in the toilet, since later the work will become more complicated due to the fact that it cannot be spoiled. It is important to initially decide which installation option is more convenient in your case; there are two solutions:
- Overhead a fan is a familiar option to everyone. In it, the mechanical part is hidden in the ventilation shaft, and on the outside there is a cover with a decorative grille. The advantage of this solution is that the installation process is quite simple and takes a little time, but the disadvantage is that during operation, noise will be heard in any case, in expensive models it is less, in cheap ones it is more;
- Duct fan - more rational decision In my opinion. Although it is somewhat more difficult to install, due to its location it makes much less noise. In addition, such options have higher performance and are themselves more reliable and durable (I drew this conclusion from personal observations).
If you live in an apartment, then you know firsthand that foreign odors from the lower floors can enter your room through the common ventilation duct. To avoid this, I recommend buying a fan with check valve for a toilet or bathroom.
Its main feature is this: when the system is not working, the entrance to the cavity is closed by a thin curtain, and when it is turned on, the air flow bends it and freely goes into the ventilation duct.
If you have decided on the type of design, then you can go for the desired option. The main thing is not to make a mistake when choosing and buy high-quality and reliable option. I will tell you what factors you should pay attention to in order to choose the best solution:
| Duct diameter | You must measure this parameter in advance in order to look for exactly what you need. Naturally, the size of the fan or its part recessed into the shaft may be slightly smaller, but if it turns out to be larger, then you will either have to change the product or carry out labor-intensive work to expand the cavity, which is extremely undesirable |
| Performance | It is believed that for efficient work even under the most difficult operating conditions, the fan must pump about 10 room volumes per hour. Since the size of the toilet is usually small, there is no point in purchasing overly powerful models. |
| Material of manufacture | Most often, polymer materials are used to cast the body. It is better if it is ABS plastic; it is highly resistant to impacts, does not turn yellow over time and retains its strength over a long period of time. Carefully inspect the surface - high-quality products will never have flaws, untidy seams or dirty stains |
| Noise level | The maximum that can be used in a toilet is 40 dB, but these days most products are quiet. The highest quality options are almost silent |
| Voltage | I recommend using only equipment rated for 12 volts. Why? It's simple: it is absolutely safe when used in a damp environment and the level of energy consumption will be minimal |
The fan can be mounted on bushings or bearings. The second option is much preferable; it is both more reliable and durable.
Overview of the main manufacturers
As for the products on the market, the buyer may have problems choosing due to huge assortment products. I will tell you about those options that have proven themselves with positive side and enjoy deserved popularity among customers.
I'll start with the Vents brand, which offers a fairly wide range of modifications, the main product groups are the following:
- Axial fans have a variety of designs and good technical indicators, as for the price, depending on the brand, the product will cost you from 650 to 2800 rubles. Silent models deserve special attention; their cost is about 1600-2000 rubles;
The Vents 100 Quiet model is low noise and energy saving, with a power of only 7.5 W and a capacity of 97 cubic meters per hour.
- Centrifugal duct options are suitable for the lower floors of high-rise buildings and places where the resistance in the ventilation system is high. The cost of the product, depending on the power, can range from 2900 to 5000 rubles.
The products of the Domovent company are distinguished by reasonable prices and good performance indicators; I would divide all products into two groups:
- Axial fans have a fairly attractive design, and their cost, depending on the model, ranges from 650 to 1000 rubles. At the same time, the quality meets all standards; such structures can be used in any type of premises;
- Duct fans from this manufacturer will cost you from 380 to 650 rubles. This is one of the most budget options, but the performance of the design will be even higher than that of axial models due to the fact that the system is located in the ventilation shaft.
The Polish company Equation offers overhead fans with stylish design and low noise level. The appearance of the products corresponds to the most high standards, the cost ranges from 1000 to 3000 rubles.
The Spanish brand "SATA" offers high-quality and reliable equipment that has an attractive appearance and good performance characteristics. Axial modifications will cost you from 1600 to 7000, and channel modifications will cost on average from 4 to 7 thousand rubles.
Another Spanish brand that is very popular in our country is “Silent”, the products of this company are different highest quality and reliability, but the price is much higher than that of usual options. So overhead models will cost you from 2 to 7 thousand, and channel modifications can cost from 6 to 50 thousand.
The Ballu company produces very high-quality and reliable, but at the same time inexpensive fans. The cost on average ranges from 1200 to 2600 rubles. On my own behalf, I would like to note that this option is one of the best in terms of price-quality ratio.
"Ballu" - good decision for any bathroom
Another company that cannot be ignored is Electrolux. This Swedish manufacturer produces a wide range of high-quality household appliances, including fans. Their cost, depending on the brand and power, ranges from 1,600 to 8,000 rubles.
Installation
Now let's figure out how to install a fan in the toilet, the work is not difficult, however, the installation instructions must be followed very carefully, because the work involves electrical equipment. First you need to decide on the type of connection, there are the following options:
- If the design includes a timer, then the system is connected according to the diagram below. Power for the timer is supplied from the lamp so that the system turns on after a certain time or at the same time as the light turns on. This option is convenient to use, but sometimes you need to turn off the fan and turn it on, which automatic system difficult;
- You can make the same system, but implement the ability to turn it on using a switch. It must be installed in the toilet within human reach. This solution is convenient due to the fact that you can turn the system on and off yourself, but if you do not touch the switch, it will work without your intervention;
- The simplest, but also the most reliable option is to turn the equipment on and off yourself. Again, control must be carried out directly from the toilet, which is important to provide for when carrying out finishing work and install the switch in advance;
- An improved type of the equipment described above is a design in which a time relay is present. That is, turning on is done manually, and turning off automatically after a certain period of time. This is very convenient, because as practice shows, many people forget to turn off the fan, and it can work for almost days;
There are other options, but there is no point in describing them separately, because they are connected in the same way, they just have in the design additional elements: humidity sensor, temperature sensor, motion sensor. In the toilet, it is advisable to use only the last option; the first ones are basically useless.
Do-it-yourself installation includes several main steps:
- First of all, you need to turn off the power to the network. The entire system or a separate part of it, which is responsible for the toilet, simply turns off. Don't forget to check if the electricity is turned off, otherwise, if you mix something up, the result will not be the most pleasant;
- Next, you need to take care of the lighting of the workspace. Most often, there are no windows in the toilet, and if the lights go out, you are unlikely to be able to work without a flashlight. Many people forget about this aspect and, as a result, have to work in the dark or urgently look for a flashlight from neighbors or in their own pantry;
- Before installing an exhaust fan, you need to connect the power supply to it. The ideal option is from distribution box, there you can make a high-quality connection and lay the cable to the ventilation duct. If the finishing is done, then there is simply no other option other than connecting to the light bulb, you need to be powered by, the wire is most often laid along the ceiling finishing (if you have plaster, you will have to install a cable channel);
- If the system starts working when the light is turned on, then you need to conduct the circuit through the light bulb, detailed diagram there is higher;
- If installation is carried out in a shaft, it is important to position the structure as tightly and securely as possible. If you don’t want to carry out this labor-intensive process, then the best solution the pipe will be brought outside, a fan will be built into it, and an air intake will be placed at the end;
- If you implement the option with a switch, then do not forget to run the wire to it as well. Although in this case I would advise implementing the connection with a cord; in the overhead structure there is a chain hanging, by pulling which you turn on the system. This design is much easier to connect, because you just need to connect the fan to the network, and there is no need to route the cable through a switch or light bulb;
Leave a supply of wires so that if necessary, you can pull the fan outside for inspection and service without damaging the connections.
- After you have connected the structure using one of the methods, you need to check the functionality of the system. To do this, turn on the electricity supply and you test the fan; if everything functions as expected, then work can continue. If the design does not work at all or does not work as it should, then a search for the problem is carried out; it may be an incorrect connection or poor contact in any connection;
- As for fastening the element, there may be two options. If the body is solid, then liquid nails are applied to the back of the frame, after which the structure is put in place and pressed tightly. If the design has a fixing frame in which the fan snaps into place, then you first need to glue it and then simply put the main unit in place.
Conclusion
Always try to choose the best option - a silent one with a check valve and a timer. You should not skimp on quality and comfort; it is better to purchase a more reliable option. Certainly, correct installation is no less important, so watch the video in this article, it shows the process clearly; if you don’t understand something, ask questions in the comments.

Today, a toilet hood with a fan is considered a necessity, and not a whim of residents. With its help, unpleasant odors are removed and the room remains fresh. But in order for the system to work effectively, first of all you need to correctly select the required power, and also install it taking into account all the requirements.
Features of choice
When choosing a device, you need to pay attention Special attention both safety during operation and operational efficiency. Both parameters are key.
If installation is carried out on your own, then you need to learn well design features fan for toilet and bathroom. This will allow you to choose the ideal option for a specific room and needs.
It is important to exclude advice from hardware store salespeople for several reasons. This is due to their narrow knowledge in the field of installation and installation of ventilation, which is limited to the store’s assortment. In addition, they often want to sell stale goods on the shelves, so give good advice don't intend to.
Installation of an exhaust fan. How to do it.
In this regard, you need to choose a fan yourself. To make the right choice, you first need to know what types of such devices there are. There are 2 main types:
Installation methods
It is important to remember that the installation of a fan in the bathroom must be carried out during renovation work, otherwise the finish will be damaged. In addition, you need to decide Which option will be more convenient for installation - duct or overhead.
Both the first and the second have their pros and cons:
A common problem is the spread of unpleasant odors from the lower floors of the house. To prevent this situation, it is recommended to use a hood with a toilet valve. It works on a simple principle. If the fan is not turned on, it is closed by a thin flap (valve). When the blades begin to spin, the air flow bends the damper and draws air out of the room. When you stop again, the valve closes again and prevents excess odors from entering the room.
Specifications
When the type of design has been chosen, you can go shopping to a specialized equipment store. It is important to choose a high-quality and reliable model.
One of the necessary technical characteristics when choosing is the diameter of the device. These details must be known prior to purchase. If the model is slightly smaller than the required cavity width, then there is nothing to worry about. But if, on the contrary, there is more, then you will have to do additional work to prepare the site for installation.
The performance should be sufficient for the full operation of the ventilation system. To be more specific, then in 1 hour the device should pump up to 8-9 volumes of the room. Due to the fact that the square footage of a bathroom is usually small, there is no point in buying fans with too much power.
Manufacturing material - plastic. Household fans for bathrooms and restrooms are made from polymers. This is due to the low cost of production. But do not think that equipment made of plastic will not have sufficient strength. Modern production is on quite high level in technical terms. The only thing worth paying attention to is quality. Good products will not have uneven seams, surfaces, flaws, etc.
The operating volume also needs to be taken into account. It should be no more than 35 dB. Although today it is very rare to find such models. Typically, most products good producers They make virtually no noise.
You can choose from two fan mounts possible options- on bearings or bushings. The option with bearings is better, since the device will work much longer.
Good ventilation is extremely important for bathrooms and toilets. It ensures clean and fresh indoor air. Natural ventilation does not always save the situation. Sometimes it is advisable to purchase exhaust fans for the bathroom and toilet.
Exhaust hatches installed in old buildings many years ago no longer effectively cope with their functions. In addition, some apartment owners make repairs, remodel the bathroom and even block the ventilation holes in order to isolate themselves from their neighbors. Air purification is also often hampered by clogged hoods. Over time, all ventilation channels become clogged with dirt and soot.
Fan on the wall of the bathroom
However, we should not forget that even not very old system may not cope well with the task, since the mechanism of operation of such ventilation is based on the difference in temperature in the house and outside.
During the hot season, the ventilation system works at half capacity. Therefore, even in new buildings with relatively good systems air exchange, many residents still think about how to choose an exhaust fan for the bathroom.
Standard bathrooms in regular multi-storey buildings small in area. Filling the bath hot water, every time we notice that a tiny room literally turns into a steam room, condensation appears on the floor, mirrors and walls. If the ventilation system is not debugged, constant high humidity leads to the fact that the tile cladding loses its attractive appearance, the tile seams turn black, and mold can settle on the walls.
Darkening of tile joints in the bathroom due to dampness
The absence of a natural light opening in the bathroom requires mandatory equipment vent. Such a system will become the only source of air penetration.
Ventilation is provided for in every house design, but its operation does not always fully ensure proper air exchange. That's why many people, when starting renovations, wonder how to choose a fan for the bathroom.
What to consider when purchasing a product
If you're not yet sure which fan to install on your bathtub, there are a few factors to consider. The choice of model may be influenced by the number of people living in the apartment and the size of the bathroom. If you use the bathroom mainly in the morning and evening hours, and during the working day the apartment is empty, it makes sense to think about saving energy and installing a blower with the functions of turning off the device and adjusting the power.
Today there are products with a timer on sale.
Bathroom fan with timer
This is a very functional device, since its operation can be set for a strictly defined period of time. For example, an exhaust fan in a bathroom with such a mechanism works exactly half an hour after you have used the bathroom. In this case, you set the time that is convenient for you.
Types of bathroom fans
When choosing a particular model, you need to take into account its functionality. There are standard and automatic hoods. The standard air exchanger is a traditional axial system equipped with a check valve. It prevents exhaust air from penetrating back into the room. This design is well suited for bathrooms in which the ventilation system is combined with the kitchen. Air is drawn out of the bathroom or toilet area, but does not enter the kitchen.
Appearance of a standard axial fan
The operating principle of such a supercharger is very simple and is directly related to turning off the lights. The hood starts working as soon as the light in the bathroom turns on, and when turned off, the fan itself stops. This is convenient for using a bathroom, but is not very effective at very high levels of humidity in the room. In order for all the moist air to escape, you need to leave ventilation system turned on for a long time.
A more expensive ventilation option is to purchase an automatic device with a timer and humidity sensor. This device allows you to turn it on for a certain period of time. For example, an exhaust device with a function automatic shutdown works for about 25 minutes after you leave the bathroom. The humidity level sensor sends a signal to the system that the permissible limit has been exceeded, and the fan begins to function. After a period of time you set, it turns itself off.
Exhaust system with humidity sensor
For arranging a hood with common system For several apartments, products with a check valve are usually used. This device prevents air from flowing back into the room from the ventilation. The valve protects the apartment space from dust, clogging with small particles and poplar fluff.
In addition to the above functions, such a fan reliably protects the bathroom from foreign odors that come from neighboring apartments, for example, from tobacco smoke.
When choosing a particular model, pay attention to the device’s performance, type of design, noise level and reliability.
Hood performance parameters
The main indicator of a fan's performance is its performance. The higher it is, the better unpleasant odors are eliminated in the bathroom and steam comes out. Typically, standard systems have an output of fifty m3 per hour. Sometimes such a hood is not enough, and apartment owners additionally install a fan.
Fan in the bathroom interior
To calculate productivity, use the following formula: the volume of the room must be multiplied by the multiple. If the number of people living in the house is 1 or 3, the multiplicity is 6. If more than three people use the bathroom, the multiplicity is 8.
Let us give an example of such calculations. There are 3 people in the family. The length of the bathroom is 3 meters, width – 2 and a half meters, height – 3 m. We calculate the fan capacity as follows: 3*2.5*3*6. We get the number 135 m3/h. Thus, it is recommended to purchase a fan with this performance.
Reliability and safety of use
One of the main criteria for the quality of a device is its protection from moisture. In the bathroom, drops of water can fall on the fan, so the equipment must have special markings confirming protection from moisture to avoid short circuits.
As a rule, fans are marked IPX4. This indicates that the device is safe and has good protection from water.
Fan noise level
The fan should not cause discomfort to the apartment owners during operation. It is desirable that the noise emitted by the device does not exceed 40 dB.
Low noise fan
Structure and types of ventilation equipment
Today on sale there are many big choice products for bathrooms and toilets. Before making a choice, you should study the range well and understand the types of structures.
According to the installation location, for example, the most popular are wall models. They also produce ceiling fans for the bathroom, how to choose quality product, you can find out from our article.
Ceiling ventilation unit
Some devices are mounted behind a suspended ceiling. Fans can also be configured as axial, radial, duct, centrifugal and centrifugal-axial.
Axial models are the most common. They are quite powerful and easy to install. Such equipment provides air circulation up to one hundred cubic meters at one o'clock.
Axial exhaust fan
However, they are advised to be installed when the horizontal section ventilation duct less than three meters.
Centrifugal-axial devices are characterized by even greater power. They are also suitable for installation in a part of the duct that exceeds 3 meters.
Appearance of a centrifugal axial fan
The centrifugal fan works very efficiently. This a good option for installation in the bathroom, but such models make a lot of noise.
Additional properties and uses
Modern manufacturers produce fans with many functions for ease of use. Thus, devices with humidity and motion sensors are very popular among buyers. Such fans turn on automatically in cases where ventilation of the bathroom is required.
Ventilation system with motion sensor
Installation
Installation does not require special skills. It is only necessary to observe safety precautions, as when working with other electrical devices.
It is advisable to install the fan immediately during overhaul. Then it will be convenient to supply electricity to the place where the device is mounted. The next step is to install the switch. They differ somewhat in structure. One switch is designed to illuminate the ventilation device. The other, consisting of two buttons, is used separately - for light and for ventilation. Sometimes you also need to configure the remote control.
For products with built-in humidity sensors, a switch is not required.
After laying the cables and installing the switch, you can proceed directly to installing the fan itself.
Exhaust fan installation
To do this, you need to remove the cover and coat with glue the part of the device that will be attached to the bathroom wall. Then the blower should be inserted into the hole in the wall and wait for the glue to dry. After this, you can connect the device to the power supply. Finally, the protective grille and mosquito net are fixed to the device using self-tapping screws.
Thus, ventilation devices for a bathroom or toilet can be easily installed with your own hands. This mechanism is necessary in the bathroom; its operation significantly improves the service life of the bathroom, since it effectively eliminates dampness and excess moisture. Thanks to large assortment There are enough products to choose from a budget option. It is not at all necessary to choose the most expensive fan.

What are the criteria for choosing a hood for a bathroom? How practical is a bathroom fan with a timer? How to install it correctly in a room with a suspended ceiling? What should the connection of the device to the power supply look like? In this article I will try to answer these and many other questions.
Forced and natural
- When is forced ventilation necessary?
Here are the signs that it's time for you to go to the store for a range hood:
- In the bathroom between visits the water on the walls does not have time to dry;
- Appeared on the ceiling or in the tile seams fungus;
It may also be a consequence of periodic flooding by neighbors above or faulty plumbing equipment. Leaks of risers in the ceiling are especially insidious: there are no visible defects, but the ceiling of the lower apartment is constantly damp.
- The air is constantly humid and musty;
- Towels and laundry items smell musty.
Find out how effective natural ventilation, a couple of simple tests will help:
- Hold a piece of paper near the ventilation duct grille. During normal ventilation operation, it should be pressed against it by the air flow;
- If this does not happen, repeat the experiment with a match or lighter. If the flame brought to the ventilation duct does not deviate towards it, before installation forced ventilation the channel needs cleaning.
Ventilators are on staff of service organizations; All cleaning work is free for residents. The exception is the case when the channel is clogged due to their fault (for example, construction waste during repairs).
Go shopping
Now let’s talk about how to choose a fan.
Performance
- What should the hood output be?
If it serves only a bathroom or a combined bathroom, productivity is selected at the rate of 7 - 9 cubic meters per hour per square meter area. So, for a bathroom with a typical Khrushchev area of 2.5 square meters, the required minimum is 2.5 * 7 = 17.5 m3/hour.
In practice, the performance of fans with an impeller diameter of 100 mm usually starts from 50 - 80 m3/hour. This allows you, if necessary, to regulate the speed by dimming the device while maintaining acceptable ventilation quality. However, I will touch on the topic of connection in a separate section.
In Soviet-built houses, a more typical ventilation scheme is in which all air exchange in the apartment is carried out only through ventilation ducts in the bathroom and kitchen. The air flow is ensured by gaps in the wooden frames.
- Supply plastic windows supply valves;
- Provide forced air exchange taking into account the area of residential premises. For rooms, the air exchange rate is 3 cubic meters per hour per square meter. The required performance can be distributed across all ventilation ducts - in the bathroom, toilet and kitchen.
Installation method
- Which fan should I install - overhead or duct?
The invoice is practical in the following situations:
- It is installed instead of the ventilation duct grille directly on the wall;
- It is placed in a suspended ceiling, the design of which prevents air from escaping through the cracks(for example, plasterboard).
If the ceiling is made of panels or slats, a duct fan installed directly into the ventilation duct or air exhaust pipe is preferable. IN suspended ceiling a hatch is installed for its maintenance and replacement.
The photo shows a hatch for access to a duct fan in the suspended ceiling of my attic.
Basic functions
- What should you pay special attention to when purchasing?
To noise level. Silent operation is ensured by:
- Plain bearing. Unlike rolling bearings (roller or ball), it does not rattle when the impeller rotates;
The bearing bushing must be bronze. Play will quickly appear on the steel bushing, which will lead to an increase in noise level.
- Rounded blades. Square or pointed blades are noisy at high speeds;
- Small angle of attack of the blades;
- Closed impeller. Air is sucked in through a hole opposite its center or through a gap on the sides.
Additional functions
- What additional functions can hoods be equipped with?
Here is a short list of possible options:
- Autonomous power supply. The fan can operate on batteries or from a built-in rechargeable battery that is charged from the mains. Autonomy will be very useful in case of frequent power outages or in country houses;
- A bathroom fan with a humidity sensor turns on when the humidity threshold is exceeded. It will work for some time after taking a shower and turn off on its own, without creating unnecessary noise and saving energy;
- The timer will allow the hood to turn off some time after the bathroom light is turned off. Of course, it will only work if the fan and light are powered through a common switch;
- The check valve will prevent the occurrence of reverse draft in windy weather. It ensures that your bathroom will not be saturated with aromas from neighboring apartments;
- A low-voltage hood, powered by 12 volts, will be very useful in bathrooms with LED lights. Both it and the fan are powered through a common power supply, outside the bathroom. This scheme guarantees your safety: even when short circuit you will not receive an electric shock.
Captain Obvious reminds: choosing a fan with abundance additional functions not always justified. The more complex the device, the higher its price and the lower its reliability.
Let's start installation
into the wall
- How to install an overhead fan in a horizontal ventilation duct?
Installation is carried out using galvanized self-tapping screws with a length of at least 60 mm. They screw into plastic dowels, inserted into holes drilled in the wall around the ventilation duct. The grooves for fastening can be seen on the hood body, under the removable front panel.
Elongated grooves are more practical because they allow the fan to be leveled after the holes have been drilled in the wall.
After attaching the fan the gaps between its front panel and the wall are sealed acrylic putty. It will prevent exhaust air from entering the room. The elasticity of acrylic will allow the seam to withstand the inevitable vibration during fan operation.
To the ceiling
- How is installation carried out in the case of a suspended ceiling?
The hood body is attached to Molly dowels through holes pre-drilled in plasterboard or other material. When tightening the fastener, its shell creates a reliable stop with a large area on the back side of the ceiling.
- How to fix a ceiling fan in case of a suspended ceiling?
The socket of a rigidly fixed ventilation pipe. Opposite the socket, a cutout is marked in the stretch ceiling; then a reinforcing ring is glued onto it, after which the fabric inside the ring is cut out. The overhead hood is inserted into the socket using silicone sealant.
A nuance: it is much more reasonable to equip the ventilation duct with a duct fan, and the canvas -ventilation grille. Ideally, the space above the hanging or suspended ceiling must be ventilated. Otherwise, high humidity will quickly lead to the appearance of fungus on the ceiling and walls.
- How to install it yourself in case of duct fan and a plastic ventilation duct?
The fan is placed in the pipe socket, after which it is fixed in it with a second tightly inserted pipe. I used for a 100mm duct fan sewer pipe with a diameter of 110 mm and a compensating pipe.
The hood is placed in a compensator on silicone and fixed in it with a pipe. The power cable is routed through a hole drilled in the compensator with a diameter of 6 millimeters.
A private house
- How to bring a ventilation duct to the street in a private house?
I made it through load-bearing wall on the ground floor and through the gable under the eaves on the attic. The ventilation outlet is equipped with a corner and an umbrella-deflector. The deflector prevents water from entering the ventilation system in rain and oblique winds, and also further enhances traction in windy weather.
Electricity
- Which could be the most simple circuit hood connections?
The simplest option is to connect via a switch common to the fan and bathroom lighting. The wire is thrown directly from the light bulb socket. Main disadvantage Such a scheme is that the hood is idle for most of the day, while the bathroom needs ventilation constantly.
- How to connect a bathroom fan to a switch, ensuring its operation independent of lighting?
It's very simple: use two-gang switch. Neutral wire - common for light and ventilation; the phase is hung on different buttons. In my opinion, this scheme is the most practical.
The most sensible solution is to connect ventilation to a separate switch key.
- Is it possible to regulate ventilation performance?
Yes. I used a regular incandescent dimmer for this purpose. Statements that I periodically encounter on thematic forums that fans require some special dimmers - clean water fairy tales: the lighting dimmer works great with any hood.
Dimming allows you to flexibly regulate fan speed, choosing between the maximum volume of pumped air and silence.
