Fans window of the increased power. Supply fan: duct, window and ventilated, smart supply fans

In rooms where it is impossible to arrange ventilation through the walls, household window fans are often used. These devices are necessary to remove exhaust air from the premises, although they can also supply fresh air from the street. This makes window fans a versatile tool for any room. They can freshen up the air in your home.

The window got its name because of the possibility of its installation in the window opening. Installation is carried out after equipping the window with a hole of a given shape and a certain size. At the same time, the installed fan can pass air only in working condition. When the device is turned off, the inlet is blocked by various special devices (blinds, grilles, etc.).

Window fan: application

Window fans are used indoors to force or remove air from outside. In other words, when installing a fan, the use of a ventilation duct is excluded. In this case, a hole in the wall serves as a channel or window opening. The thickness of the partition can be clearly regulated.

A feature of the use of exhaust window fans is the need to create a hole of a certain size and shape. Basically, this hole is round, with a diameter corresponding to the size of the channel.

The fan is fastened with special screws or screws due to various special elements, which pull together the response elements of the structure.

Window fan: types

Centrifugal.

Window axial fans are considered the most common type, providing for the movement of air along the axis of the entire electric motor. They are supplied with many different protective elements and can perform the functions of injection and exhaust.

Centrifugal models are fans with high performance. Their disadvantage is the protruding mandatory body located indoors.

Window fan: forms and applications in the interior

There are several options for their implementation. Each of them corresponds to the shape of the hole made for them. The most common shape is round, requiring holes in the window glass, wall and other partitions. The popularity of this form is due to the ease of making such recesses in the glass.

A special type of fans that allow the presence of holes of various shapes are window models with a screed and fixation. This type of these devices makes it possible to use holes that do not extend beyond the front part or body.

Window fan: accessories

The ventilator is a ready-to-use piece of equipment, although various options may be applied to it to provide different functionality.

As additional devices can be used:

Gravity or automatic blinds;

Check valve at the outlet of the fan (for exhaust models);

Protective grilles located at the outlet and inlet;

Automation devices and electronic control operating modes of each model;

Decorative elements.

Thanks to its small size and light weight window fan can be installed directly on 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 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 can interfere with the use of large ventilation systems. In the same time, axial fan with blinds can be no less effective, and in some cases even more convenient device. 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:

The axial fan window is very popular. It is simple in design and has 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.

Window window fan

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 blinds are equipped 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.

How to choose a window fan?

How to choose a window fan for an apartment?

Window fan - one of the modern effective ways ensure ventilation in the room. Its installation is possible directly into the window by replacing part of it or by making a cutout of the appropriate shape in the glass. Installing a window fan does not require significant financial or time costs. Many works can be done independently, without involving specialists from outside. .

The use of small window fans is typical for residential premises, offices and catering establishments. AT industrial buildings larger fans are used. They allow you to maintain clean air with a constant influx of pollutants.

Installing the fan in a window opening, it is easy to hide it with curtains or blinds. With the help of such fans, you can both create a complete ventilation system and improve the circulation of air masses in stagnant zones. The service life of such devices is 10-15 years, and a wide selection of devices in terms of power, dimensions and features of use makes it possible to choose the best option for any room.

Types of window fans

There are a huge number of window fans. First of all, they are divided into industrial and domestic. Industrial devices have significant dimensions and high power. Therefore, their scope is large buildings, they are not used in apartments and private houses. A feature of the operation of industrial devices is the operation of three-phase current.

Axial window fan is very convenient household appliance, which is designed to serve a small area. Many models have blinds or lids that close when the appliance is turned off.

Axial window fan

Depending on the design, there are:

• Exhaust.
• Supply and combined.
• Supply and exhaust fans.

Exhaust devices designed to remove polluted air. They are installed in kitchens, bathrooms, toilets, workshops and laboratories.

Supply fans allow you to create an influx fresh air in office rooms and living rooms where there is no need to remove dirty air.

The increased pressure created by the window inlet fan will cause the air to be drawn through the ventilation ducts. The most efficient system supply and exhaust type . which simultaneously removes polluted air and provides an influx of clean air from the street. Such functions are performed by a window reversible fan, which is equipped with an electric motor of the appropriate type.

A variety of window fans are devices that are installed in the window.

Features of window fans

Household devices are characterized by low power. They consume 15-25 watts. On the other hand, their design ensures a low noise level.

Louvred window fan

Household exhaust window fan makes up to 3 thousand rpm. Such fans are well suited for operation with a significant temperature difference between the room and the street, which reaches a maximum of winter period. Change weather conditions also does not affect the efficiency of these fans. The case and the main elements of the fan are made of plastic, resistant to various influences - high temperatures, shocks, ultraviolet rays. It can be operated at temperatures from +50°С to -50°С.

An important issue is the preservation of heat. For this, a window fan with shutters was developed. An alternative to blinds is a cover. The louvered fans close when the engine is switched off. Soft rubber sealing strips are provided to eliminate gaps between the case and the window. For fans with a cover, when it is closed, the motor turns off, which simplifies device management. The advantage of this design is the absence of reverse thrust.

Fan selection

The main question when choosing a fan is the purpose of its application:

• For kitchen, bathroom and toilet - Exhaust type fans are suitable.
• To the rest room or hall - it is recommended to install supply fans.
• Supply and exhaust type devices are equally well suited for all tasks.

However, their cost is higher than that of devices of a simple design.

To accept correct solution how to choose a window fan, you should pay attention to its main parameters - performance, power, dimensions. They determine the capabilities of the device and how it is used. The most popular is the axial fan of the simplest design, which is characterized by high efficiency and good aerodynamics.

When choosing, it is necessary to take into account the volume of air to be moved and the purpose of the room. An important parameter is the number of changes in the total air in the room per hour.

Knowing the size of the room where the fan is to be installed, it is easy to calculate the required system performance. For example, a kitchen with a volume of 30 m 3 will require a fan with a capacity of at least 300 m 3 / h.

A window fan can be a good alternative to a window fan. First of all, when choosing it, you need to pay attention to the dimensions of the device and the equipment with protection - blinds or a cover. At the same time, such a fan should not take up too much space or interfere with sunlight.

Smart supply fans

Smart supply fans include full-fledged systems for constant supply and purification of air such as . This intelligent device is a supply fan with air heating to your chosen temperature, 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.

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 ventilators are used not only in private houses. 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 specifications 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. A more efficient exhaust system 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 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, 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.

Before installing a window fan, it is necessary to evaluate its technical parameters and capabilities, as well as the size of the room where the installation is supposed to be. Modern systems have a reduced noise level (25-30 dBA) and will not cause discomfort in connection with this. Spending a small amount of electricity, they at the same time provide significant air exchange that meets sanitary standards.

For a simple device robust design window fans do not require expensive service - it is enough to periodically clean its parts from dust.

Installation

Installing a window fan is a simple process and does not take much time. The device has a small weight and size, which allows you to install it directly in the window, cutting a hole in the glass of the appropriate size. In order to ensure a snug fit of parts and assemblies at the installation sites, special components and fasteners are provided to ensure complete tightness. To eliminate noise, noise-insulating gaskets are used, which are also advisable to use during installation.

How to choose

In order to make the right decision, particular attention should be paid to the power, performance and dimensions- these parameters are of particular importance during installation and further operation. The most popular option is the axial window fan, which is characterized by simple design, high efficiency, good aerodynamic characteristics.

When choosing, the volume (m3) and the purpose of the room are taken into account. So, for a bedroom, an air exchange rate (the number of air changes per hour) is 2-4, for a living room - 3-6, for a toilet - 6-10, for a kitchen - 10-15. Based on the required air exchange rate, it is possible to calculate required performance system by multiplying the specified parameters. So, for a kitchen of 10 m2, a device with a capacity of at least 100 m3 / hour will be required.

An analogue of window fans is a window fan, which is installed in the windows, performing the same functions. In accordance with the size and shape of the window, you can choose exactly the device that is most suitable in a particular case. A separate, high-tech model of this type is a ventilated supply and exhaust fan, which provides ideal possibilities for cleaning and fresh air supply. To protect against the ingress of air from the outside in the "off" position, it is recommended to purchase an inexpensive ventilator with a cover.

The size of the device should correspond to the size of the window or vent, without taking up too much space. large area without interfering with the penetration of sunlight. It is also important that the shape and design of the device fit into the overall interior.

To ensure the removal (inflow) of air in large volumes, in some cases, window three-phase fans can be used. Such fans have increased performance characteristics and are used as auxiliary in and facilities.

Kinds

Depending on the direction of movement of the air medium, window fans are divided into:

• exhaust;
• supply;
• supply and exhaust.

Important!
Exhaust fans, provide an extract of especially polluted air. This category includes kitchens, bathrooms, toilets, small laboratories and workshops.

A window supply fan will help solve the issues of fresh air supply to the office, to living rooms where there is no need pre-extraction polluted air, and a slightly increased pressure of fresh supply air will help freshen the air in the room.

Particularly effective is supply and exhaust system, providing at the same time removal of the polluted air environment and inflow of fresh air. A window reversible supply and exhaust fan can perform these functions. Depending on the need for cleaning or fresh air supply, devices of this type can perform both specified modes of operation. To do this, the device is equipped with a reversible electric motor powered by a 220 V network.

Power supply

Some models of this type are equipped with transformers that reduce the mains voltage to 12V and ensure complete safety for users. Each modern window reversible fan is equipped with a position switch that allows you to manually switch speeds, operating modes (supply-exhaust), as well as turn the device on or off. If desired, you can order a device with a remote control.

The innovative DC reversible DC motor has speeds up to 3000 rpm and low power consumption. The DS motor is designed for 12V voltage, operates in two-speed mode and has a reduced noise level due to special constructive solutions. A particularly attractive feature is its reliability: the motor is protected against overheating, is designed for continuous operation and does not require maintenance.

Peculiarities

Window fans are fully adapted to work in conditions of temperature difference: changing weather conditions, especially in winter, do not affect their efficiency. A modern household exhaust window fan has a housing and most of the components made of heat-resistant, shock-resistant, thermoplastic ABS plastic, which equally well perceives both high (up to +40 ° C) and low (up to 30-40 ° C) temperatures outside the window, is resistant to exposure to ultraviolet rays.

The window louvered fan, which extracts the exhaust air, is equipped with special devices - shutters, which automatically close smoothly when the device is turned off, thus preventing reverse draft (air from outside). A simpler device is a window fan with a cover, in which a cover is provided to prevent the flow of air from the street, which can be closed manually if necessary.

Easy maintenance, efficient operation, innovative technical properties and characteristics provide the ever-increasing popularity of window fans.
