Installing a Window Fan in a Window

The main task of an axial window fan is to effectively ventilate the room to which it is attached. The device creates an influx of fresh air from the environment, while preventing insects or birds from entering the room from the street.

In this case, the vent fan has the function of extracting stagnant air from the room to the street. There are both household types of such fans (low-medium power) and industrial ones (they have very high performance, usually large sizes).

Design Features

The compact device is mounted in a window, fixed in the opening, and improves air circulation. You can organize ventilation of both individual zones and full ventilation of the entire house or building. For an ordinary apartment, private house or office space, the power of such a fan is sufficient. Other systems with higher power are used in production.

The design is lightweight, so it is possible to replace part of the window opening or to attach it to it. On top there are curtains or blinds that move apart or rise during operation. The fan refreshes the room in a short time, so there is no need to open the windows. This feature allows you to protect the room from cold, excess heat, and street noise.

In rooms with this type of equipment, heat loss is reduced by up to 50%. Another important advantage is protection from dust, debris, and insects entering the rooms. You can choose fans of any shape, and the variety of types allows you to significantly expand their scope of application.

How to choose a hood?

When selecting cooling systems for a bathroom, it is necessary to present certain criteria by which the final decision is made. If the initial question is the choice between price and quality, for an effective purchase you will have to understand this topic more deeply. Options:

Performance. In order to calculate it, you need to multiply the volume of the bathroom, i.e. length, width and height by the number of air changes in 60 minutes. The average should be between 95-100 m 3 / hour.
Noise level. There are two different types of noise - mechanical and aerodynamic. The first comes from the parts of the system, and the second from the air itself. Noise levels should not exceed 25 dB .
Safety. First and foremost, keeping moisture out is a major concern for every bathroom fan. Therefore, you should once again check with the seller in which room it can be installed.

Division by type

Fans for windows are divided into two categories: according to the location of installation and the direction of fresh air flow. Their main types are: axial, household and industrial. Axial ones are of supply type, exhaust type or supply and exhaust type. They differ in the following characteristics: functionality, appearance and power.

Household fans are notable for their low power, but they look beautiful and complement the design of the premises. Axial devices are simple in design, industrial ones are characterized by high power.

Axial

These fans are a complement to a regular kitchen hood. They are used to remove polluted air from the room and quickly get rid of unpleasant odors. The speed of the blades is 4 thousand revolutions per minute, but they have a relatively low noise level and low power consumption. The device removes moisture and excess heat. This type of hood is equipped with blinds that prevent the flow of air from the street into the room.

Window-type supply fans are designed to deliver oxygen into the building. This can be any residential buildings, offices. It should be taken into account that rooms containing plasterboard structures require constant ventilation. The frequency of fresh air inflow is related to the number of people in the premises and changes taking this into account.

Complete ventilation is provided by supply and exhaust window fans. Using filters, air flows are cleaned on both sides. Outdoor – warms up when it intersects with the exhaust air.

Devices for home use

These household appliances are easy to install, ventilate the room without cooling it, and eliminate the entry of dirty air with dust from the street. The device is small in size and, when operating at a low noise level, consumes electrical energy sparingly.

Air is delivered to the living space every two hours, this meets the standards. The device provides ventilation and regularly maintains a comfortable microclimate.

Industrial

Such fans are installed only inside warehouses and production workshops. The fan is more powerful, supplies clean air with oxygen and removes toxic odors. These devices are installed during the installation of windows, in specially prepared openings. The length of the blades of some of them reaches 1 meter.

Recommendations for selection

For an apartment, it is better to choose a supply and exhaust model.
A wide range of models is associated with the possibility of using a particular device in a wide variety of operating conditions.

Before choosing a device, you should familiarize yourself with information on suitable power. Powerful fans are usually installed in industrial premises. For an apartment, a small-sized device is enough.

If you choose a window hood for the kitchen, it is important that the fan effectively removes odors that appear during cooking. The best option would be a supply and exhaust or wall-mounted air exchanger with high power. In addition to this, a hood and an additional air vent are installed in the kitchen. It will help clean the kitchen space from excess heat and fumes.

Bathrooms and toilets are rooms with high humidity, where the risk of mold and mildew formation increases. It is also necessary to remove unpleasant odors from the bathroom. The best choice is a wall-mounted fan, which is installed together with a check valve. The system is often connected to lighting. When the light is on, the air exhaust will work, and when it is turned off, it becomes inoperative. This scheme is simple and effective.

A window hood is usually installed in a room or hall. It is sufficient for small spaces. Many experts advise installing supply and exhaust fans simultaneously for maximum air exchange. Then the room will be constantly filled with oxygen, which will help you have a comfortable rest.

How is installation carried out?

The type of window opening determines how the fans are installed. The device is installed according to the general algorithm. First, the serviceability of the shaft in the room is checked, then markings are applied to the window under the air duct. Holes of the required diameter and size are cut. If the windows are plastic, you will need the help of a professional. The equipment is installed on a special frame, which is pre-fixed. The device is attached and connected to the electrical network.

Installation of window fans depends on the type of glass unit. If the house has double-glazed, single-glazed plastic or wooden windows, remove the glass from them and cut out a hole of the desired shape. The field of this is installed in place, and then the device is mounted.

For metal-plastic windows, a more complex method is used, requiring the help of specialists. The glass is removed, and a new one with a pre-prepared cutout is installed in its place. It is important here not to damage the seal of the glass unit.

Device installation

It is necessary to understand that installing window fans in glass is a complex task that requires special skills, which sometimes even professionals do not undertake.

During installation work there is a high probability of seriously damaging the glass!

In this case, you will have to purchase a new double-glazed window at the same time. For this reason, it is recommended to contact a specialist. Metal-plastic double-glazed windows are usually immediately replaced with glass with a cut-out opening for the fan.

Installing exhaust window fans in a single-glazed window involves several steps:

Cut an opening in the glass that matches the size of the device body.
Insert the housing into the opening and secure it.
Seal all joints, cracks and holes with high-quality sealant or cover them with rubber seals.

Methods for installing and attaching an exhaust model to a window may vary depending on specific conditions, type of glass and fan parameters.

Helpful Tips:

If you plan to install a new plastic window, then it is best to order the installation of the device immediately during the manufacture of the window. Specialists will make a special limited opening with a hole.
The device body cannot be mounted in ordinary glass, as there is a high probability that it will crack or break during operation.

Installing a window fan in a plastic window

It is advisable to install the flow valve on plastic windows (PVC). It is provided for horizontal fastening to the top sash directly on the window profile. Its main task is to help ensure natural ventilation.

Wherein:

the valve does not block the window opening, as it is located on the profile;
promotes the flow of fresh air from the street;
The sound insulation of the window remains unchanged;
no heat loss;
When installing the valve, the integrity of the window profile is not compromised.

The device has both manual and automatic control. Made from materials: wood, metal or plastic. With automatic adjustment, the ventilation process is carried out without human intervention. This occurs due to changes in air pressure or humidity. When choosing, you should take into account its level of sound insulation and remember the rules of care. The grille of the external visor must be cleaned of dirt, and the body of the device must be wiped of dust.

A reliable method of ventilation in PVC windows is a supply valve

It is difficult to imagine modern housing without metal-plastic windows. The popularity enjoyed by PVC windows is great; they have long replaced ordinary wooden windows, as 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 destruction, 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 the 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 formation of frost inside the window frame, extending the service life to unlimited. According to the evaluation 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. The old way to solve this problem is ventilation. In rooms where plastic profiles are installed, it can be carried out by general ventilation of the room or by opening windows in the rooms, but this option is fraught with drafts, dust, and disruption of sound insulation. All properties of PVC windows, with normal ventilation, are reduced to nothing.

Installing a Ducted Window Exhaust Fan

This type of device is usually used in rooms with high air humidity and where there is an unpleasant odor, such as kitchens, toilets and bathrooms. Heavy, dirty air with unpleasant odors goes out the window, and oxygen comes in in return (naturally).

The main advantages of an exhaust fan are: high performance and ease of operation. Some models are equipped with a remote control.

The device operates regardless of air temperature, its installation is simple and does not require special knowledge and skills. A fan with an air duct can be installed either in a hole in the wall or in a window. Thanks to this feature, installation is quick.
