The fan is window forced-air and exhaust. Window extract fans
Every person strives for comfort, which begins with the arrangement own house. Clean air, the optimal level of humidity in the room, normal air circulation - the necessary conditions human life. These indicators are health and comfortable conditions labor and rest. For ventilation of premises, a window exhaust fan is increasingly used. Window fans contribute to the continuous renewal of the air, which guarantees a comfortable stay in the house.
Exhaust window fan improves quality of life
Household window fans, types, characteristics
Window exhaust fan - a special device used for household purposes for cleaning, extracting air from rooms, stabilizing optimal level humidity and circulation. An analogue of a window fan is a window fan installed directly in the window, hence its name.
Thanks to similar principle work, characteristics and dimensions, these devices are interchangeable. The window model is mounted directly in the window, on the window, by the window, its dimensions, the choice of the device model, the diameter of the device, the size of the hole in the window frame for installation is determined. The power of the model is selected according to the area of \u200b\u200bthe room. The window fan serves for a long time, up to 11-14 years, the operating temperature of window fans varies from - 40 ° C to + 40 ° C.
Window Fan Features
household window fans have a number of characteristics that distinguish them from other ventilation devices:
- minimum energy consumption;
- low noise level;
- equipped with blinds, which contributes to the preservation of their tightness;
- the built-in external cover protects from hit of rainfall;
- small sizes;
- affordable prices for appliances;
- simple installation;
- Possibility to control the speed with the remote control.
There are many factors to consider when choosing an exhaust fan.
When buying a fan, consider the following characteristics:
- noise level of the model;
- the power of the device must correspond to the living area;
- equipping the device with devices that eliminate the effect of back draft insures the device against insects and
- dusty air.
The window exhaust fan works as a hood, the exhaust characteristics of this type are optimal. The air flow or jet of air is directed outward, from the room to the street. Main tasks:
- drawing out excess heat;
- excess moisture;
- various gases;
- dust.
Such models will consume up to 10–20 W, and perform up to 4 thousand rpm. Household fans, made in Italy, are adapted to work in rooms where there is a significant temperature difference between the house and the street, such a room is a vestibule. The temperature difference in the vestibule of the dwelling reaches its maximum during the heated period.
The peculiarity of this room is a sharp temperature drop with the formation of a large amount of condensate.
In the vestibule, it is better to install an exhaust window fan made with special blinds, such a device retains heat. The fan shutters are closed when the power is switched off, in this device there is no back draft, due to which heat is lost. And fans with a cover are also used, the principle of their operation is the same as that of a fan with shutters.
Window fans are made of plastic
window exhaust fans made of plastic, this material has heat resistance, impact resistance, and is immune to ultraviolet radiation. Plastic elements fans undergo special laboratory testing, the plastic must withstand temperature fluctuations from +50°C to -50°C.
Varieties of window fan
There are many types of window fans. Common are: window exhaust, window reversible supply air.
The window reversible fan simultaneously performs two tasks:
- elimination of polluted air;
- supply of clean air.
Ventilation in windows, by means of a reversible fan, is reliable and efficient. Such a fan changes the direction of the moving air jet, works as an extractor hood, in the mode of removing exhaust air, and in the mode of inflowing clean air from the atmosphere. The operating mode is set automatically or using the control panel. Advantages of window reversible fan:
- simple installation: you can install the equipment in the window reception and attach it with bolts;
- the installation of a fan does not require an air duct system;
- fans are small;
- have a convenient operation mode.
When installing window fans, the question often arises, which fan to choose for a particular room? The fan is selected according to the type of room in which it is planned to be installed. For bathrooms rooms will do installation of exhaust or reversible fans, for kitchens - only exhaust fans, for living rooms - installation of supply units. Practice has shown that Italy supplies the most functional and most reliable models to the market.
Reliable way of ventilation in pvc windows - supply valve
It is difficult to imagine modern housing without metal plastic windows. The popularity enjoyed by PVC windows is great, they have long supplanted ordinary wooden windows because they have a number of advantages:
PVC windows have a long service life
Plastic window profiles are well protected from damage, they are reliable and easy to use. Each plastic window has drainage holes that protect the structure from moisture that can accumulate in it from outside. Drainage holes are located in the profile of the window frame, they must be present in all pvc windows. Drainage holes protect the profile from water and prevent the appearance of frost inside the window frame, extending the service life to unlimited.According to the estimated characteristics, pvc windows have no equal, but there is one drawback, plastic windows are not equipped with built-in ventilation ducts, so there is no ventilation system in pvc windows. old way The solution to this problem is ventilation. In rooms where plastic profiles, it can be carried out due to the general ventilation of the room or open windows in the rooms, but this option is fraught with drafts, dust, and sound insulation. All properties pvc windows, with normal ventilation, are reduced to nothing.
How to ensure ventilation in an apartment with sealed plastic windows
The owners often ask themselves: how to make ventilation in an apartment with plastic windows? Right choice– installation of the supply valve on the window profile. Supply valve- this is a special device that is mounted horizontally on the top sash window profile, the main task of the valve is to restore natural ventilation in room. The supply valve facilitates the inflow of fresh air from the atmosphere. There are several important advantages of the device:
The supply valve is necessary for the influx of fresh air from the atmosphere
- the valve does not close the window opening;
- the valve contributes to the supply of fresh air;
- ventilation occurs without loss of warm air;
- the valve does not affect the sound insulation level of the profile;
- ventilation without harm to health (no draft);
- autonomy from the window profile;
- installation of valves does not violate the integrity of the window frame.
Supply valves are different types: made of wood, plastic and metal. The valves can be controlled automatically and manually. Automatic adjustment is effective and convenient, since the need to close and open the ventilation duct is determined independently, without human intervention. The valve is adjusted by changing the pressure and changing the humidity in the room.
It is better to install the valve directly with plastic windows, in plastic windows, on plastic windows, with this type of installation, you do not need to use the wall near the window, changing its appearance. When choosing a valve, it is necessary to study its characteristics regarding sound insulation, the metal-plastic profile should have similar characteristics. It should be remembered that the valve must be looked after - periodically cleaning the grille of the outer visor from dirt, wipe the valve body with a damp sponge.
Efficient ventilation of housing is the preservation of health and comfortable pastime.
A variety of ventilation devices helps to choose the best way for your home. It is important to remember that any ventilation device has both positive and negative characteristics, so its choice should be made carefully and deliberately.
Thanks to its small dimensions and low weight, the window fan can be installed directly into the window. Installing soundproofing pads will eliminate excess noise. Installation of window fans does not require significant financial investments. Most of the work can be done independently without the involvement of third-party specialists.
Such devices are used in various fields of activity: manufacturing organizations, office companies, catering and at home.
By mounting a window fan in a window opening, it is easy to hide it with curtains or blinds, there are windows in every room, which will restore normal air circulation in problem areas. The service life of the device reaches 10-15 years, and various options power, diameters and technical features allow you to choose the best option for any area.
Varieties
There is a huge variety of fans. They are divided into household and industrial. A small area or finished decoration in an apartment can interfere with the use of large ventilation systems. At the same time, an axial louvered fan can be no less efficient, and in some cases even more convenient. Sometimes the blinds close automatically when the appliance is turned off.
Window fans are classified depending on the direction of movement of the air. They are:
- exhaust;
- supply;
- supply and exhaust.
The axial fan window is very popular. It is simple in design and has a high efficiency.
The window fan has an analogue - a window fan, operating on the same principle, with similar characteristics and dimensions. It is not difficult to understand from the name that it is installed in the window. It is recommended to buy such devices with a cover. In the "off" position, the cover protects against the ingress of air from outside.
To supply air flow in large volumes, it is appropriate to use a three-phase window fan. He possesses high performance performance, which allows them to act as assistants in industrial applications.
Axial types are used for installation on walls and panels. Their feature lies in the ease of installation. They can be placed in any position. These include reversible ones, which have an impeller that provides the same work in any direction of rotation of the blades.
Features of modern technology for ventilation
Home appliances are characterized by low energy consumption, low performance and little noise. In rooms where the system of ventilation shafts is not provided, optimal solution is the use of axial fans. When connected to power, the maximum voltage is 12 V and the torque is 3000 rpm.
Modern household fans are equipped with shutters for tightness when the device is turned off. A special outer cover also provides for the exclusion of precipitation. Direct and reverse mode of operation provide a change in the direction of air flow.
It is very convenient to use axial fans, but sometimes you can get more benefit from a supply and exhaust (reversible) device. Such a window fan simultaneously removes dirty air, and provides a room fresh air.
So, we list the features of such household devices:
- small size;
- acceptable prices;
- excellent temperature resistance;
- easy installation;
- speed control;
- low noise level.
What to give preference
When choosing, pay attention to the purpose of its use. Exhaust fans are suitable for the kitchen. In a room or hall, an inlet type would be an excellent option. For the bathroom and toilets it is better to use reversible ones. But it is worth considering that protective shutters or a cover must be installed on the device. Of course, you should give preference to automatically closing blinds, but the cost will be slightly higher.
Window fans provide a constant renewal of indoor air. This is very important not only in offices, where a fresh breath of air adds energy, but also at home, when you want to relax after a hard day's work. So home appliances for ventilation become great solution in various buildings.
Inline fans are usually installed as part of a general ventilation system buildings, they are used by cafes, restaurants, other catering enterprises, and they are also used to create professional ventilation in residential buildings- both in the whole house and in a separate apartment.
Duct fans require impressive ventilation shafts, they are usually mounted to walls or ceilings and closed decorative boxes. Before installing such a device, it is necessary to check the serviceability of the entire air exchange system in the building, install outlets on the roof or integrate private duct ventilation into common system ventilation in the house, and the fan itself is sensitive to the ingress of foreign objects and needs to be protected from them.
Who will suit?
Duct fans are best suited for residents of private houses, townhouses or multi-level apartments where there is enough space for a duct system.
When to install?
The best thing duct fans installed at the construction stage or overhaul to immediately integrate the system into the rest of the building communications.
What is the price?
From 3,000 to 130,000 rubles, excluding installation, the creation of ventilation shafts and an exhaust fan.
The window fan is installed in a hole in the window glass. Usually for its installation choose the most stuffy, warm and wet room so that the temperature difference between the incoming and inside air stimulates air exchange, but there are also “self-sufficient” models with power supply and constant air supply. The unambiguous advantages of such a fan include its compactness and ease of use, however, for the most part, such systems, together with fresh air, supply precipitation, noise and cold into the room. The supply and exhaust fan is also quite widespread. window type, such devices combine the functions of supply and exhaust, which affects both the size and the price of the device. A window supply fan with a filter is an extremely rare phenomenon; in the vast majority, only a protective mesh from large debris is provided.
Who will suit?
Residents small apartments in apartment buildings, residents of private homes without the ability to do .
When to install?
We recommend working in summer period, since during installation the window swings open and the room may freeze.
What is the price?
From 1,200 to 13,000 rubles.
Window fan
The window fan is perhaps the simplest and most well-known on the market. Also in Soviet time these not very attractive devices were installed in the window vents and provided air flow. The window fan is selected according to the size and shape of the window and is easy to install. On the this moment manufacturers do not separate window and window fans, and most window fans can be installed in the window and vice versa.
Who will suit?
Residents of small apartments in apartment buildings, residents of private houses without the ability to make supply ventilation through the wall.
When to install?
In any season.
What is the price?
From 1,000 to 12,000 rubles.
Smart supply fans
Smart supply fans include full-fledged systems for constant supply and purification of air such as . This smart device is a supply fan with air heating to the temperature you choose, a multi-level filtration system from dust, allergens and unpleasant odors and opportunity automatic control in the MagicAir smart microclimate system. The functionality of the breather and the absence of street noise, dirt and precipitation make it similar to duct devices, and the noise level of the device and compactness - with window and window fans.
AT recent times plastic windows are increasingly being used 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 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;
Drilling a hole for installing a vent valve

And from the side of the street
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. It is worth noting here that with the complexity of the design, a large amount of light flux is lost, which makes the room rather 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, 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 when in large numbers 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.
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 have been preserved, and making a hole (or it already exists in the form of a window) is not 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.
Rice. 1. Window fan is the easiest and most affordable
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 in size, inexpensive, consume little energy, have a low noise level, they are easier to install than any other modern technology.
With the help of a window household fan it is possible to ventilate the dwelling 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 warehouses, 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 time immemorial 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 room is industrial, then of course it will be a 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 are a lot of extraneous 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 vent 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, due to which fungus forms. 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 installation spaces supply fan will be more than enough, although many advise installing both supply and exhaust for maximum air exchange, 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.
