Which supply valve to choose: types of valves in the wall, selection criteria and an overview of the best manufacturers

The popularity of plastic windows is due to the tightness of the structure, the ability to effectively isolate itself from external noise. However, many owners of such systems are faced with the problem of a lack of fresh air supply. As a result, the windows fog up and condensation forms on them. The high level of humidity in the area of ​​window structures contributes to the development of fungus, mold, significant deterioration of the indoor climate.

There are several ways to restore balance. One of the simplest but most effective methods is to install a supply valve. A simple device will provide an optimal air exchange rate, help to solve the problem of excess humidity, and create a favorable atmosphere in the room.

To make a good purchase, you need to figure out which supply valve to choose, what brands to pay attention to. This is what we will talk about in our article. We will also pay attention to the design features of such a ventilator and the principle of its operation.

When is a supply valve needed?

Due to the massive replacement of wooden window systems with plastic structures, the efficiency of natural ventilation has become significantly lower. If air from the street easily penetrated into the room through the micro gaps between the wooden doors, then the sealed plastic structures excluded this possibility. In such a situation, the speed of movement of air flows is significantly reduced, which negatively affects the microclimate in the apartment.

In addition to reducing the level of comfort in the room, insufficient air flow can lead to more serious problems, including:

1. Increasing the concentration of carbon dioxide - a high content of carbon dioxide with a lack of oxygen leads to a deterioration in general well-being, the appearance of lethargy, drowsiness, irritability. In addition to reduced performance, many have an increased susceptibility to viral diseases.
2. Accumulation of allergens - in rooms that are poorly ventilated, pathogenic organisms are actively developing. They are capable of provoking allergic reactions.
3. Bad smells - when the rate of air renewal is low, odors that appear as a result of cooking, the life of people, animals linger in the apartment.
4. Excess moisture it is absorbed by all wooden surfaces, accelerates the corrosion processes of metal products.

Installing a supply valve easily solves these problems.

The key task of the supply valve is the uninterrupted supply of fresh air from the street. Such a solution is relevant when the general ventilation of the house does not perform its functions correctly and an additional inflow of air masses is required.

The use of a supply valve allows not only cleaning, but also, in some cases, heating the air coming from the street.

Installation of the device does not require significant financial costs. Due to its small size, you can install valve anywhere, the beauty of the decorative design of the room will not be disturbed.

Design features and principle of operation

Looking through the information about which model of the supply valve is better to choose, where to install device, it is important to first understand the design features, as well as study the principle of operation devices.

In fact, the valve is a cylinder equipped with a filtering and noise reduction system.

Next, we will consider in more detail about the main structural elements of the supply valve:

• Air supply valve. It looks like a plastic tube with a diameter of 6-14 cm. The performance of the valve, the maximum volume of air that can be supplied to the apartment with its help, depends on this parameter. Through the tube, air from the street enters the room.
• Ventilation grill may have a different appearance, differ in functionality. The simplest option is an aluminum or plastic mesh that prevents debris and large insects from entering the apartment. More advanced models provide protection from precipitation, are equipped with a mosquito net that can resist flies, mosquitoes, midges.
• Head (work intensity regulator) - an element that closes the valve from the inside. It provides air flow regulation and is attractive in appearance. The dimensions, shape, location of the openings that allow air to pass through may vary from model to model.
• Heat and sound insulation of the valve. To prevent the wall in contact with the air duct from freezing in winter, the plastic tube is lined with heat-insulating material along its entire length. Often, the product is in the shape of a sleeve.
• Wall ventilator filter. The material is located in the head, does not allow dust, pollen, and other allergens to enter the apartment. Different fillers are used depending on the model and brand.

An additional element in the design of the supply valve is sealing ring, damper. Thanks to their use, strong gusts of wind do not cause discomfort during the operation of the device.

The principle of operation of the ventilator is as simple as its design:

1. Air is taken from the street through the grate.
2. Passing through the air duct, the flow heats up.
3. The filter removes dust from the air masses.
4. The flow rate is regulated by a special damper.

If there is a supply valve, air enters the apartment without interruption. In this case, the windows will be closed, the cold, dust from the street will not penetrate into the room, as with ordinary ventilation.

When installing a supply valve, it is important to understand that ventilation problems cannot be solved only by creating an air supply. To ensure a healthy atmosphere in the room, it is necessary to adjust the operation of the hood, to create conditions for the movement of air flows between rooms. For this, gratings are installed or a gap is left between the sash and the floor of at least 15 centimeters.

To understand the intricacies of creating effective air exchange in rooms, we recommend that you familiarize yourself with the rules of arrangement ventilation in a private house or apartment.

Types of supply valves

Today manufacturers offer a variety of ventilator modifications.

Among them:

• window fittingshaving a constant cross-section;
• wall modelsequipped with a regulator of the intensity of air supply;
• forced air wall valve.

To choose the best supply valve and install it in a window or wall, it is important to understand how the models differ.

All models perform one task - they provide a healthy atmosphere in the room, increase the rate of air exchange. However, differences in design lead to differences in the functionality of the fixtures.

Type # 1 - ventilators for plastic structures

Supply valves designed for PVC windows are considered the most common solutions to ensure effective air exchange in an apartment or a private cottage. Structurally, a window ventilator is not much different from a wall ventilator. It is a slot equipped with flaps. The productivity of the device ranges from 3-7 cubic meters per hour.

Most often, window ventilators are used for plastic structures that provide high tightness. However, they can also be installed on wood or aluminum systems.

For the window inlet valve to function correctly, the following conditions must be met:

• there must be a working hood in the room;
• the temperature difference in the apartment and on the street must be at least 5 °.

The disadvantage of using the device is the likelihood of a drop in air temperature during severe frosts. Unfortunately, it will not be possible to completely close the window valve. To ensure insulation, its outer part is sealed.

The advantages of window ventilators include:

• the small size of the device, which is located on the sash, does not spoil the interior;
• mounting does not require a professional tool, special skills, half the time does not take more than an hour;
• when using the valve, sound insulation is not disturbed;
• the air entering the room is directed upward, which excludes the occurrence of drafts;
• affordable cost.

Due to the variety of models, you can choose a supply ventilation valve with the required performance.

View # 2 - wall valves with air regulator

The supply ventilation valve can be equipped with manual or automatic control.

In the presence of an electronic controller, the devices respond to pressure drops, the level of air pollution in the room, and humidity indicators.

The features of the operation of wall models practically do not differ from the use of window valves, except for certain points:

• wall ventilator capacity can reach 70 cubic meters per hour;
• the device is equipped with a filter that cleans the air;
• installation of the device is more difficult, requires the use of professional equipment.

In addition to all of the above, wall models are equipped with an air supply regulator.

Thanks to the design features of the device, moisture from the street is prevented from entering the room, and a high level of sound insulation is provided.

A feature of the operation of wall models is the need for maintenance, which is not known to all users. Every season it is necessary to disassemble the supply valve and clean the filters.

Type # 3 - valves with mechanical ventilation

Forced air models have the following design features:

• use of an electrically driven fan;
• the presence of additional filtration;
• provision of heating of air streams.

Forced air devices are characterized by increased performance. They provide a supply of up to 120 cubic meters every hour and are equipped with carbon filters that can thoroughly clean the incoming stream from harmful impurities.

The advantages of such solutions include:

• efficient work even in the absence of a working hood;
• high quality cleaning of the air entering the room;
• quick normalization of the humidity level in the apartment.

The only drawback of a forced air valve is its high cost.

Such a device can be installed in any convenient place, without being tied to heating radiators that heat the air masses coming from the street.

Ventilator selection criteria

Studying the features of various modifications of the supply ventilation valves and figuring out which option to choose, it is worth considering the main criteria that affect the comfort of using the device:

1. Bandwidth - will allow you to assess what rate of air exchange the supply valve will provide, whether it is enough for a particular room, the number of households living in it.
2. Working temperature - valves with a metal air duct often freeze. Choosing a product with a plastic tube, the probability of freezing is significantly reduced.
3. Adjustment type - automatic control over the operation of the supply valve ensures the comfort of operation of the device. The possibility of mechanical adjustment will allow you to change the intensity of the incoming air flow with a sharp temperature drop.

Sometimes DIYers make their own supply valves. This saves money, but does not provide a sufficient level of operating comfort.

A quick overview of the best manufacturers

When choosing a ventilator, users rely on different criteria. One of the important indicators of the duration and quality of the supply valve is its manufacturer.

But sometimes the characteristics indicated in the product passport do not correspond to reality. In order not to face such a situation, you should choose valves from well-known brands with a good reputation.

Next, we will briefly consider the best brands whose products are presented on the domestic market.
