Ventilation valve in the wall: device and installation

It is not so rare to hear that apartment owners in large cities do not have enough clean indoor air. Kitchen smells and fumes, condensation on the windows and metal objects can make the home microclimate completely uncomfortable for permanent residence. Lack of ventilation must be addressed. This can be achieved by installing a supply valve in the wall. With its help, an additional supply of fresh air to the room will be provided. Most often, installation is done in the kitchen space. After installation, the formation of mold or fungi of various origin becomes practically impossible, and the increased humidity in the room no longer entails any negative consequences.

Internal structure design

You can find many models of supply valves in the modern construction market. However, the device they all have in common.

Components:

1. Air duct Through this pipe, air masses enter the room from the outside. The most common ducts made of plastic.
2. Ventilation grille (it can be seen from the outside of the wall). It prevents various debris from entering the room.
3. Noise isolating composition.
4. Ring and damper performing sealing function. They are against the wall of the house from the inside. These parts can hold back strong gusts of wind.
5. A filter in which the supply air is cleaned.
6. Knob for adjusting ventilation.

Installation of the supply and exhaust valve can be performed independently and at any stage of construction or repair. No electrical connection required.

The principle of operation of the installation

With the help of such a device, it is possible to forcefully create the movement of air masses in a room.

Through the grate, air flows move along the main pipe of the structure. Further, material for sound insulation is overcome. Already at this stage, air is purified from heavy mechanical impurities. Next, there is a decrease in the speed of air flow, at the same time it is rough cleaning. Air enters the room from here through special openings.

Using a special button, it is possible to control air circulation, the flow rate can be adjusted. Drafts do not occur. Excessive moisture and street noise remain outside the apartment.

Pros and cons of wall ventilation

Installing such a design will be useful to everyone. There are several good reasons for this:

• reduced wear of window fittings (it is not often necessary to open and close windows in a house);
• from the street, much less noise irritants penetrate the apartment;
• there is the possibility of self-regulation of the exhaust ability of ventilation;
• in the cold season sharp jumps in temperature are equalized;
• the design can easily be disguised, but even in open form it does not spoil the overall interior;
• inexpensive cost.

As elsewhere, there are also negative aspects to the supply valve installation:

• you will have to make a hole in the wall. If the structure is to be dismantled in the future, the through hole will not go anywhere.
• every mistake made during installation entails the onset of negative consequences. For example, it is possible to freeze in the winter.
• in many areas of the country in the winter, it will simply not be possible to use this installation. Otherwise, the air in the room will become very cold.

Basic rules for design selection

When choosing a ventilation valve, it is important to pay attention to the temperature range at which it can function properly. All sizes and dimensions also need to be given due attention. The wall in the house should be less than the length of the main pipe. The size of the inner cover is selected based on the capabilities of the internal structure of the house.

In cold climates and poor heating power, a large installation will allow such volumes of air that it simply will not be able to warm up. If too little air enters, then several structures may be required.

There is a high probability of provoking drafts if the supply valves are mounted in walls opposite to each other.

Possible costs

Prices for the mechanism and installation of ventilation can have significant differences among themselves. Domestic installation costs, as a rule, one and a half to three thousand rubles. The cost can be doubled if it comes to imported designs. For installation work, you can invite an experienced builder with your tool. All the work will take him no more than an hour. But the waste will increase.

To obtain benefits and savings, many undertake to do this work on their own.

The main stages of installation

First of all, it is necessary to determine the place of installation work. Despite the fact that the internal appearance of the home does not deteriorate with the installation of the structure, it is still recommended to mount it under the windowsill. The explanation for this is simple - the air from the street enters the heating pipes, and it spreads around the room already in a heated state. However, the final choice still remains with the landlord.

1. In the selected section of the wall, it is necessary to drill a hole, which should be through.
2. In this hole, the main pipe is installed together with the external grill.
3. The space around the hose is filled with insulation.
4. Then you need to assemble the valve. This will require a scheme provided by each manufacturer.
5. The cover together with the adjustment knob are mounted at the final stage of work.

Having completed all these uncomplicated steps, you can begin to use the ventilation design.

There is another popular way. The hole is drilled behind the heating pipes. In this case, several points become winning at once. The supply unit is securely masked. The incoming air begins to spread throughout the room only after it goes around the heating radiator. That is, there is a movement of air at room temperature. This means that you should not be afraid of even a very strong cooling. Air masses entering the house are cleaned, refreshed and filled with heat.

The collection and installation of such a design is not such a difficult task. Any person can handle this. One of the most important conditions is to carefully read the attached instructions from the manufacturer.

Tools required for installation:

• hammer drill. Be sure to have a drill bit of the required size;
• a set of drills capable of drilling brick and concrete panels;
• screwdrivers;
• the design itself.

The scope of such designs is diverse. They can be mounted in apartments and houses of the private sector, office buildings and large factory premises. Hospitals, schools, kindergartens - places where a large number of people accumulate, and therefore the need for additional air in the room arises constantly. Such an installation will not be superfluous anywhere.
