Installing an axial fan in a window. Window reversible supply and exhaust fan

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: industrial 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 let you pick 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 may 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 the room with 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.

Today, for domestic and industrial needs, not only new 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.

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 shutters, it will be possible not to think about the back draft that exists in conventional hoods, since the shutters prevent this moment.

Supply window fans

The supply air exchanger works opposite to the exhaust air exchanger. With its help, air flow is supplied, 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 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 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 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 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 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 a supply and exhaust fan 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 almost all residential premises have 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.

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. Air flow or a jet of air 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 close when disconnected from the mains, there is no reverse draft in this device, 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 extremes 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 plastic windows. The popularity enjoyed by PVC windows is great, they have long supplanted ordinary wooden windows, since they have a number of advantages:

high tightness;

excellent sound insulation;

easy installation;

long service life;

shock resistance;

heat resistance;

drainage holes in the profile structure.

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 in the profile 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 inlet valve promotes inflow 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 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.

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. Installation of this design will not require significant financial investments, and will ensure the flow of 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 places where unpleasant odors accumulate. More efficient exhaust system it is not always possible to install due to its design characteristics. It is then that it is advisable to install a 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 body;
• 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.

By cons this device can be attributed:

• during the operation of the window mechanism in winter time warm air is ejected from the room and cold air is forced in. 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.
