The fan is window reversible forced-air and exhaust. Varieties of window ventilation systems

AT recent times are increasingly being used plastic windows in various areas of construction of buildings and structures. Due to the majority of advantages, these structures can be used both in residential construction and in industrial construction. They protect well from heat and cold, prevent the penetration of noise and various odors, as well as harmful insects. But there is a huge drawback, which is to prevent the penetration of air into the room.

Here it can be noted that this is not entirely a lack of plastic. It can be noted that these particular structures are not provided for houses that were built in past centuries.

Ventilation and plastic: compatible or not?

Why in modern world have not yet come up with a way to effectively ventilate windows? Here you need to be more imbued with the question. Everything here was based on the presence of an exhaust hood in the kitchen and bathroom, as well as ventilation through the door and window slots. This technique was invented a long time ago and has already met the expectations of the inventors.

And now you can look at this invention from the side of arranging new plastic windows. When the structure goes through the installation process, all cracks and gaps are sealed, thereby forming humidity in the room. This disrupts natural air exchange due to no air entering the room. Indoors at home or it becomes stuffy, humid and discomfort begins. Here such a process can also begin, which will be as follows: all the air will not leave the room, but will remain constantly there, and also all the smells from the neighboring apartments will be completely felt by you.

Here you can highlight other problems that arise during operation. Due to the constant closing of windows, condensation may form inside the structure, which will prevent the normal use of materials. It is best to keep the windows on the micro-ventilation function to prevent fogging of the windows.

Plastic window ventilation mode

Of course, you can get rid of such problems with a simple ventilation in several built-in modes. Also, when purchasing, you should consider the number of cameras. In the presence of a cold temperature regime, it is better to buy multi-chamber windows that will retain heat much better. Of course, you will have to overpay for the quality, but the result will not keep you waiting.

Combination of ventilation and windows

Is it possible to combine ventilation and windows? The answer is simple - you can. There are quite a few options for the device. There are quite a few combinations, some of which are:

• with a window;
• with self-ventilation;
• with a comb;
• with ventilation valve;

Windows with a window

A fairly common method of ventilation, which has been used for quite a long time. It provides for the intake of air under the ceiling in the room, which then mixes with the room air, thereby forming a cool and clean product. It eliminates the appearance of drafts or condensation in the window.

The disadvantages of this design are a rather large increase in the cost and complexity of the design, which increases the weight of the materials. Here it is worth noting that with the complication of the design, the a large number of light output, which makes the room quite dark. This is not always good.

Plastic windows with self-ventilation

Self-ventilated windows are the best option for the device in all buildings. They can be used both in civil and industrial construction. This option lies in the fact that the structures use profiles with holes at the top and bottom of the frame. Holes are located in the upper inner and lower outer parts. Air masses passing through lower part are heated, and already heated air enters the room.

The principle works very well, but has some limitations. Such structures cannot be installed on upper floors due to insufficient air supply. From such a shortcoming in many systems, a ventilation valve for windows has recently become widespread.

Windows with combs

These windows are the most widely used today. With such a device, a regulator is built into the windows, which allows you to either open the window completely or open it in several modes.

Such a mechanism is very inexpensive, but gives a pretty good result. The comb makes it possible to regulate all incoming masses and leave the window in the intermediate position mode.

Vent valve in windows

For normal operation such a device must combine several functions for full operation. Subject to such laws, the entire room will be constantly ventilated, which will ensure normal temperature regime. It should be noted here that such a valve has several varieties, which are called classes. Classes are very different from each other and have different ways installation.

To put the valve in window frame you can either replace the entire double-glazed window, or replace the part that is responsible for ventilation. There are also disadvantages, which are to increase the cost and weight of the structure. Such operations are carried out in less than an hour, but guarantee a fairly good result.

Next, you need to decide on the control mode. Here, as in any design, both automatic and manual modes can be used. These options have their own differences, which are as follows. With the help of manual ventilation, you can adjust the ventilation, thereby placing it where you need it. Partial ventilation is applicable here, which allows these processes to be carried out only where it is required. As for automatic control, then everything is very simple. The mechanism built into the windows itself regulates the required temperature and, if necessary, adds air masses of the desired temperature. However, there is a third option, which combines all the advantages and removes many of the shortcomings of the two previous modes. This is mixed mode. It allows you to customize any mode when it suits you.

Operation in winter

There may appear their own problems, which are the appearance of condensate. But such a disadvantage is impossible to predict. In all cases, everything will be different. This effect will depend on the temperature. outside air, the material of the walls, the intimacy of the windows themselves.

Climate valve

When operating in winter, it is worth noting that under any circumstances the premises should be ventilated at least 2 times a week. This will ensure a fairly durable use of structures and protect them from condensation.

Installation

Considering this question, you need to remember that it is better to hire good specialists, which will qualitatively establish this design.

With improper installation, all sorts of difficulties subsequently arise, which sometimes lead to decay with a large amount of moisture. This can lead to rather dire results and money will be thrown to the wind.

Installing a window ventilator

Very important . How to arrange it correctly - read in a separate article.

Nowadays, the industry produces a large number of a wide variety of fans. Depending on their type, there are different purposes.

One of the important functions that these window devices successfully cope with is the ventilation of the premises. This problem is relevant in modern buildings, when often the ventilation system in insufficient volume provides air replacement.

We can say that installed in the window modern device provides supply and exhaust air in the room.

Light weight appliances are ideal for window installation. Special insulating pads protect against noise. The installation of such a design will not require significant financial investments, and will provide an influx fresh air into the room. The ease of installation will allow even without the involvement of specialists to complete the entire installation without any problems.

window window fans used not only in private homes. They are successfully used in factories, shops, offices and other premises for working purposes.

The compact dimensions make it easy to mask it with curtains or blinds.

High service life (more than 10 years), a huge variety in power, design and other technical characteristics allow you to make a choice based on specific needs.

In most cases, window models are made of white or beige plastic.

Existing types of window fans

Primarily, they are all divided into industrial and domestic. To install an object in an apartment window, naturally, a lighter, albeit low-power apparatus is required.

All these devices are divided into:

• exhaust. Most often applicable in the kitchen or in the toilet, as well as in other crowded places unpleasant odors. More efficient exhaust system it is not always possible to install due to its design characteristics. That is when it is advisable to install the device of this type. It provides an exit of the air polluted with smells on the street. The influx of fresh air is provided either at the expense of adjacent rooms or from subsequently opened windows;
• inlet. They are most often used to provide fresh air and cool the room. Against the backdrop of expensive split systems or air conditioners, this option is very economical and affordable. However, when the street is too heat usage this method not justified;
• supply and exhaust. It is also called reversible. This is the most universal view, capable of providing both inflow and outflow of fresh air. The flow is switched by changing the direction of movement of the fan blades. The use of such a device is diverse: these are garages, and kitchens, and rooms and many other rooms where intensive air exchange is necessary. The operating mode is signaled by a special indication located on the device case;
• for ease of use, models for windows with a shutdown timer have already appeared on sale.

Criteria when choosing a reversible window fan

When choosing a supply and exhaust mechanism for windows, it is important to pay attention to its following characteristics:

• work volume. Devices emitting noise above 30 dB are not comfortable for use in residential areas. However, it is important to remember that absolutely silent designs of this type simply do not exist;
• power. Calculated based on the area of ​​\u200b\u200bthe room;
• the presence of blinds (for window models, they almost always work in automatic mode). They are used when the device is completely turned off, preventing dust and dirt from entering the interior of the building. Sometimes blinds can be replaced with a special cover, which additionally protects against moisture ingress into the device;
• if the work is to be done under conditions high humidity, then you should pay attention to waterproof models;
• For convenience of management the special panel is possible.

Pros and cons of using

Stopping your choice on the supply and exhaust window device you need to understand all the advantages that it has:

• small sizes. Possibility of installation even in a small opening;
• affordable price category;
• works both at a positive temperature and at a negative one (unlike, for example, a split system, which cannot be used in cold weather);
• simple installation. Under certain conditions, even a non-specialist can handle the installation. It also does not require the assembly of a network of air ducts for its operation. Even the presence of ventilation shafts in the building is not essential;
• the ability to control the speed and direction of rotation;
• low noise level;
• saving electricity;
• high performance;
• ease of management. There are models with a remote control.

Since all window reversible models are equipped with an anti-vibration pad, the vibration does not spread to the window.

The disadvantages of this device include:

• during the operation of the window mechanism in winter time ejection occurs warm air from the room and forced supply of cold. Thus, heat loss inside the building increases, and additional resources may be required for space heating;
• Although it is possible to select a device with a low noise level, it cannot be completely eliminated.

Installing a window fan

1. To install a reversing device, first of all, it is necessary to replace ordinary glass with a stronger material. These works are preparatory and are carried out before the start of installation. In the prepared sheet, an area for the fan housing is marked and cut out, as well as holes for mounting the device.
2. Prepared glass or cardboard is installed in the frame and securely fixed there.
3. The next step is the process of installing the fan itself.
4. This is followed by connecting the electrical cord and its output through the network loop, followed by connection to an electrical outlet.

During installation, the following nuances should be taken into account:

• if the window in which the fan is to be installed is plastic, then it is more expedient to order the installation of the device during the window manufacturing process. Then a special window with a prepared hole will immediately be made in it. At self installation there is a risk of violating the integrity and tightness of the window sash;
• fastening to ordinary glass, since during operation of the device it can crack and even collapse.

The right choice of a window air handling unit for windows, as well as its competent installation, will allow the device to work for a long time and without breakdowns, providing good ventilation in a given room.

The impeller is made of galvanized steel or aluminium, the casing is made of steel with polymer coated. Specifications differ depending on the model. Air supply speed - from 450 to 2400 m3 / h, power from 10 to 34 W. An important advantage of the window axial fan VO 220V is a low noise level, which distinguishes the series as preferable for installation in shops, restaurants, computer stores, workshops

In our catalog you can also choose fans VO 220V:

• VO-F 220V - a series with controlled rotation speed. Designed for systems of technological and general ventilation of trade and public catering establishments, workshops, small warehouses, etc. Attractively low cost. Requirements for circulating air and transported gases and vapors - non-aggressiveness, low dust content. The steel casing has a special flange for wall mounting, the impeller is made of aluminium.

• Tunnel VO - end fan for ventilation at the objects of the agricultural (industrial) complex. Mainly for providing massive air exchange in poultry buildings. Effectively performs timely removal of excess warm air in the summer. The high speed of movement of air masses along the object creates a tunnel effect, as a result of which the temperature of keeping birds in the hot season decreases to a comfortable value.

Today, for domestic and industrial needs, not only the latest technology is used, such as the most powerful hoods and air conditioners, but also a number of window fans. This cleaning option is inexpensive and quite effective, so it is still quite popular and is used in different spaces. If you are going to purchase it, first figure out what power of this device is suitable for the room where it will be installed, what functions it should perform, because this kind of fans are not produced and have different purposes.

This air exchanger is applicable in cases where it is not possible to install other air conditioning. His choice is often made either before the installation of a double-glazed window, in order to initially select the connector required for its installation, or in those rooms where wooden windows, and make a hole (or it already exists in the form of a window) - it will not be difficult.

Mounting this appliance will be necessary when condensation from moisture accumulates in basements- cellars of private houses, small industries; when several rooms are separated plasterboard wall, but require additional ventilation in order to get rid of air stagnation; in warehouses where moisture and its characteristic smell accumulate.

Installation of this unit in apartments and houses will good decision to maintain a healthy microclimate. Advantages of this solution: reliability, low noise level - within 25-30 dB; productivity, which is determined by the volume of the room. When choosing, it is worth relying on air circulation at the rate of 30-80 m3 per person.

Types of window fans

The main types of fans are the following: axial, which is divided into three more subtypes - supply, exhaust, supply and exhaust, as well as domestic and industrial.

Each of them has its own properties and differences: appearance, power, functionality. So, for example, axial ones have a simple design, but a rather large output in terms of efficiency. Household ones cannot boast of power, but they have a neat appearance, do not spoil design solutions in living space. At the same time, industrial ones are quite powerful, but their appearance does not have much weight when choosing.

Axial window fans

As already mentioned, these have a simple design. In fact, they consist of a propeller (in other words, a blade), the body itself and the engine, thanks to which the propeller is spinning. This device has an axis of rotation; air is forcibly pushed along it with the help of blades, creating a powerful stream.

Axial fans are not manufactured according to the standard, and depending on the purpose of use, they differ in the diameter of the screw (the blades can be from several meters to a couple of tens of centimeters). The number of propeller blades varies depending on the purpose, and the engine power may also vary.

Rice. 3. Simple design- but maximum benefit

Exhaust window fans

The exhaust fan acts as an aid to kitchen hood, or works independently, eliminating extraneous “flavors”. His work is aimed at removing polluted air. Due to the rotation of the blades at a speed of about 4 thousand revolutions per minute, with low power consumption, it eliminates excess moisture or excess heat, and produces some kind of one-sided air conditioning.

With the purchase of this type of hood even with blinds, it will be possible not to think about the back draft that exists in conventional hoods, since the blinds prevent this moment.

Supply window fans

The supply air exchanger works opposite to the exhaust air exchanger. It comes with air flow, but does not decrease. This type is used for such a room where there is no need to clean the air, but only to fill it with oxygen. Used in residential and guest rooms, offices.

As is known, the rate of air exchange in residential areas should be at least 30 m3 per hour per person. It is important to consider that those rooms where additional enclosing structures are located (for example, a plasterboard wall) require additional ventilation. The inflow rate also varies depending on the “occupancy” of a residential or office space.

Supply and exhaust window fans

This is already a whole ventilation system that works in both directions, performing full ventilation, both to remove stagnant air and to bring in oxygen from the street.

The reversible (i.e. supply and exhaust) fan operates in next order: outdoor oxygen is taken in and at the same time oxygen is taken inside the room, then from both directions the flow is cleaned by filters, street (often cool) is fed into a heating element(heater), in addition, the street warms up, because it intersects in the system with the one that is displayed. Such functions are inherent in this type due to its distinctive structure.

Household window fans

These have a number of advantages worth paying attention to: they are small-sized, inexpensive, consume little energy, have a low noise level, their installation is easier than any other modern equipment.

With the help of a window domestic fan, you can ventilate your home without heat loss and without dirt and dust entering the room. Oxygen in the living room should be completely updated every 2 hours, but few people follow this rule and ventilate it so often. Therefore, a household window fan, or a similar one - a window fan, will ensure regular maintenance of a good microclimate.

Industrial window fans

The peculiarity of these is their large size and use exclusively for storage facilities, workshops of small and large industries. In such places, it makes no sense to install air conditioners, but the good old fan will work out its own. In many factories, from ancient times to this day, the main “rescuer” is a fan that supplies oxygen and “takes away” pungent odors from work shops.

Usually their installation is provided during construction, and window openings have already been made taking into account their installation. These units boast big power, meter blades, but also a considerable noise output.

Features of window fans

Window fans differ in that they do not require huge amounts of electricity to operate. But with all this, they wonderfully perform their functions. Household will do a good job of refreshing the room in the house: kitchen, living room, living room, will help to cope with the problems of too humid or too dry air. Industrial, often reverse, will be able to clean the air of odors and give the room oxygen from the street.

With their simple structure, they have a good efficiency output, consume a minimum of electricity, even when large sizes, with little noise, easy to install. Environment it does not matter for the efficiency of their work, both at minus 30 and at plus 30 - the fan will perform its direct function. It is also important that special blinds have been developed for these devices, thanks to which, when the device is turned off, there is no loss of heat from the inside, and cold does not get in from the outside.

How to choose the right window fan

Manufacturers have not in vain foreseen Various types. This was done not in order to visually increase the market for this product, but in order to bring the functionality of the device as close as possible to certain conditions.

In order for the choice to be correct, it is important to familiarize yourself in advance with the information on how powerful the ventilation in the room should be. If the premises are industrial, then of course it will be powerful supply and exhaust fan. If installation is required in an apartment, then a small-sized one will be quite enough.

For kitchen

The kitchen requires a special approach, since it is in this room that there is a lot of odors after cooking. To do this, it is important to purchase a supply and exhaust, or wall-mounted air exchanger, with a fairly a good indicator power. Window air conditioning will save your neighbors from your smells, which often seep through the chimney.

In the kitchen, in addition to the hood, you just need to install an additional air outlet to clean kitchen space by taking excess heat and burning from cooking, if this is still equipped mosquito net is the ideal option.

For bathroom and toilet

In the bathroom, there is often a problem with the accumulation of condensate, which causes fungus to form. If this room is combined with a toilet (bathroom), then there is an additional problem of unpleasant odors. wall type for the toilet is a great solution, but it must be installed with check valve, in order to avoid the distillation of smell and humidity from this room to the living.

Usually the ventilation of the bathroom is connected to the lighting, respectively, when the light is on, the air outlet also works, and when it is off, it stops rotating. This scheme of work is simple, but at the same time very effective.

To a lounge or lounge

In such spaces, installing a supply fan will be more than enough, although many advise installing both supply and exhaust for maximum air exchange, hit more oxygen. After all, the room is not intended for active domestic needs, but for relaxation.

In order for the rest to be complete, before buying a fan for a bedroom or a hall, you need to find out what power the device will require, for which the volume of the room and the frequency of air exchange are multiplied according to the table below.

Installing a window fan

Installation is carried out in two ways, and the installation method depends on the double-glazed window. The first method is applicable to single-pane or double-glazed windows, often wooden, of an old design. Here, installation is not difficult, because all that needs to be done is to remove the glass, cut it to the shape of the fan that will be installed, then install it back, attaching it with glazing beads, then install the ventilation.

The second method is used more often, because in almost all residential premises there are metal-plastic windows. In order not to damage the sealing of these double-glazed windows, it is necessary to make every effort, because it is unreasonable to completely replace windows for installing a fan. Therefore, for such manipulations, specialists are invited who remove the double-glazed window, and another one is installed in its place, with similar dimensions, but already with a cut hole for the fan.

For installation, rubberized seals are used that do not allow the windows to depressurize. At a time when the device is not connected to the network, it closes the blinds that prevent heat loss.

A window fan is the simplest solution for air exchange in any room. Personally, I like this option because it does not need ventilation system, no need to make a hole in the wall, the design is placed in the window opening and is characterized by maximum autonomy and safety.

I will tell you what criteria you should pay attention to when choosing and what modifications are on the market, based on this information, you can easily understand this topic.

Even before the purchase, you need to deal with a number of criteria, and it is with them that we will begin our consideration of the topic. In the following, I will discuss the main equipment options and give specific examples and fan models to make it even easier for you to choose the best solution.

Factors to Consider

There are several main indicators that affect the choice of a fan, and the very first of them is the volume of air exchange. It indicates how many times per hour the air in the room is updated. Let's figure it out specific example: a room 3 meters wide, 4 meters long and 2.7 meters high, we calculate the volume - 3x4x2.7 \u003d 32.4 cubic meters, this is the base value.

The number of necessary air changes per hour depends on the purpose of the room, the main norms are as follows:

• For bedrooms, an indicator of 2-4 is used;
• In bathrooms and bathrooms 6-10;
• In the kitchen, you need a fan to pump 10-15 volumes per hour. If we take our example as a basis, then you will need a fan with a capacity of 324-486 cubic meters per hour.

Another factor that cannot be ignored is the size of the structure, here we can highlight the following nuances:

• The fan should be placed in the opening or window provided for it, it is better to choose such solutions that can be installed with minimal alterations to the opening;
• The design should not impair the lighting of the room if such a problem occurs, then it is better to look for small high-power products.

If you design a kitchen in a certain style, then the design of the fan should be combined with it. It makes no sense to put a futuristic high-tech option in a classic setting. Color also has great importance, and, although the bulk of products are available in white, other options can be found if desired.

It is also worth paying attention to the type of construction control, if earlier it was regular options with buttons, you can now buy systems with control panels. This is very convenient in cases where window exhaust fans located high and difficult to access.

A window fan is a kind of window fan, although some manufacturers make this product line separate. The difference is that such products are most often made under standard sizes vents, but nowadays, when plastic windows are used everywhere, there are almost no vents anywhere, you need to order the option with a vent to install a fan.

Another very important aspect to consider is the preservation of heat in the room, because through the fan the cold can freely penetrate inside. To eliminate this problem, two modifications of the equipment were developed:

• Fan with cover - in cold weather you just need to close it and the system will automatically stop working. This is a simple solution that is suitable for those who turn on the equipment as needed. The only negative is that the lid must be closed manually, and if there is no one at home, then the cold will penetrate into the room;

• Systems with automatic blinds - more modern solution, which does not need manual control. When the fan turns on, the shutters open, and when it turns off, they close, this is a very convenient and, not least, completely autonomous option that can work for years according to a given scheme without outside interference;

If you have come across fans in everyday life, then you know how important it is for them to have a minimum noise level. I have seen cheap Chinese options that, when turned on, buzz like a fighter jet on takeoff and create a huge inconvenience for everyone in the room. Choose low noise options and remember that window fans increased power always make more noise than usual.

Finally, another factor that should not be overlooked is security. Modern manufacturers offer powerful equipment with excellent characteristics that runs on a voltage of 12 volts, these are the options you need to choose. They are completely safe and cannot cause mortal harm to human health, even if short circuit, the kit comes with a power supply that connects to a regular 220 volt network.

If you have decided on the main criteria, then you can go for a fan; three types of equipment are on sale:

Exhaust fans	This option draws air from the room and is great for kitchens, bathrooms and bathrooms. It's simple: the flow is directed outward, which allows you to remove moist air and strangers as efficiently as possible.
Supply systems	Here everything is also clear from the name: such fans draw in air from outside. They are ideal for bedrooms, living rooms and other living spaces where a constant supply of fresh air is needed.
Reversible fans	In another way, they are called supply and exhaust, they can provide simultaneous exhaust air from the inside and its influx from the outside. It is this option that provides optimal air exchange and can be used in any room.

In places with polluted air, such as near busy streets in cities and near highways, it is not recommended to use supply fans.

As far as construction is concerned, any household fan has an axial device, that is, the air intake blades are located on the axis and are driven by the engine. It's simple and at the same time reliable system in which the use of high-quality components is very important.

Therefore, regardless of the brand, type and manufacturer, it is necessary to begin consideration of the option with a request to present documents confirming the quality of the product; it is better to immediately refuse options of unknown origin.

Now let's deal with the most important criteria that you need to pay attention to when choosing:

• Production material - the body and the impeller must be made of impact-resistant ABS plastic, weather resistant and ultraviolet radiation sun. The corresponding mark should be in the documents for the equipment. The surface should be smooth, without streaks and flaws;

• The equipment must have a low noise level, as well as an IP24 degree of protection, this confirms its safety for human health;
• It is important to have a protection unit against engine overheating in the design, it will prevent damage to the motor due to excessive heating.

The control system may also differ, there are several main options:

• The B type pull cord switch is the simplest and cheapest solution, the price of such options is the lowest among all;

• The system can be turned on via conventional switch, in this case, you will have to purchase it separately and independently stretch the wires from the fan to the control unit;
• A more advanced option is a thyristor equipment speed controller, it can manage both one and several units;

• The off timer allows you to control the operation of the fan. You set the operating time, and the system will automatically turn off the fan when necessary;

• You can additionally purchase an electronic control unit that allows you to set the operating mode of the system. This is perfect solution, which ensures the autonomy of the equipment without outside interference.

Choose the solution that is most convenient, it is not worth saving, because in practice it often turns out that people forget to turn off the system or do not turn it on in time. Automation will independently monitor the work and provide optimal ventilation of the room.

As for brands, there are a lot of them, but the leading position is occupied by the Vents company, these fans can be found in all regions, and they differ good quality and democratic price. I will not consider a supply fan as an option due to the inappropriate use of it on this moment, it is much more reasonable to buy a supply and exhaust option.

The most popular models today:

• "Vents VV 230" has maximum performance 455 cubic meters per hour, which is quite enough for almost any kitchen. Exhaust fan with grille on one side and automatic shutters on the other. The size of the front part is 295x295 mm, the diameter of the structure is 237 mm, the cost today is about 2500 rubles;

The BB series is a great option for kitchens and bathrooms

• The model "Vents 125MA01" has a very attractive design, on both sides there are decorative rectangular elements measuring 173x186 mm, between which a pipe with a diameter of 125 mm is placed. The design provides for automatic blinds, an exhaust fan and has a capacity of 185 cubic meters per hour, suitable for small kitchens and. As for the cost, it is about 1800 rubles;

• The supply and exhaust reversible window fan "Vents VVR 230" has a maximum capacity of 455 cubic meters per hour, is equipped with automatic shutters and can work both for air extraction and its supply. The model has a low noise level and excellent reliability. The average cost is about 3000 rubles.

If you decide to install a fan with your own hands, then short instruction will help you understand the features of the workflow:

• First you need to cut a hole in the glass. If there are two or more glasses, then the work becomes very complicated, I personally made round cutouts several times and I can say that it is very difficult. Easiest to use special device, which is called a ballerina, with its help it is easy to set the desired diameter and cut a circle on the window glass;

• Next, you need to check how the fan becomes, if everything is fine, then all seals are put in place, after which you need to check how tightly all the elements adjoin the glass;
• The mount comes with the fan, if you have concerns about the tightness of the connections, then apply around the perimeter silicone sealant, after which you can tighten the fasteners;
• The connection method depends on the control option you choose, if you choose automatic, then all the necessary information regarding the attachment of elements will be in the instructions, there should also be detailed diagram. The fan is connected to the network through an adapter;

Conclusion

Based on the foregoing, we can conclude that the supply and exhaust window fan is optimal solution for any room. The main thing is to choose correct power equipment and install an automatic control system for autonomous operation. The video in this article will help you understand some important nuances even better, and if you want to ask a question, then write it in the comments below.
