Choose a vent with a check valve

An excellent solution for arranging home ventilation will be ventilation grilles with a non-return valve.

As you know, the air in the surrounding space contains a huge amount of all kinds of impurities, which have a harmful effect on the human body.

Dust particles, various microorganisms of unknown origin, harmful bacteria, moisture and many other trace elements are regularly accumulated in the air, which simply can not be seen with the naked eye.

All this can greatly harm people's health and cause serious diseases.

To prevent this, it is important to properly equip the home ventilation system, which will effectively counteract the entry of unwanted elements into the living space.

This is especially true for the kitchen, which regularly accumulates a huge amount of unpleasant odors.

Of course, you can buy and mount a conventional ventilation system, but this will not protect the room from getting into it foreign odors and atmospheric air from the street.

The installation of an ordinary hood will help to solve the problem with the removal of indoor air, but will not protect the space from the side of the street.

In this case, the installation of a special ventilation grill, which will be equipped with a non-return valve, can become out of the way out of the situation.

Features and operating principle of

If the ventilation system is equipped with an ordinary ventilation grille, then the air from the room will be simultaneously removed and delivered from the street.

To prevent this and direct air in only one direction, it is possible if you install a ventilation grill that will be equipped with a special check valve.

This check valve is the area of ​​a certain section, which is made in the form of a circle, a square or a so-called "butterfly".

This valve has petals that are firmly attached to a special axis in the ventilation shaft. These lobes are able to pass air in only one direction.

Thus, with the direction of unwanted airflows to the kitchen space, these petals will automatically come to a position where the shaft clearance simply overlaps.

As a rule, such a ventilation grille is installed in the drawing area, and not in the interior of the mine.

The ventilation grille, which is equipped with a non-return valve, has a number of advantages.

First of all, it prevents the entry of cold and hot air from the street side into the room.

In addition, thanks to the installation of a ventilation grille of this type, it is possible to prevent unwanted dust, insects and many other elements from entering the shaft.

This ventilation grill protects the interior of the house from extraneous atmospheric odors, and by installing a special sound attenuator, muffled sounds from the side of the street will come into the room.

The only drawback that can be attributed to a ventilation grill equipped with a non-return valve is the possible freezing of its petals at low temperatures outside the window, which makes it simply impossible to ventilate the interior of the house.

However, when installing a ventilation grill of this type in the drawing area, this problem can be avoided.

How to choose?

There are several specific rules that must be studied before buying a ventilation grill fitted with a non-return valve.

First of all, you need to carefully inspect the hole in the inner drawing area and measure all its geometric dimensions and cross-section.

This is necessary for the device to really fit in its dimensions and it did not have to be changed to a new one.

In addition, when choosing a ventilation grille of this type, attention should be paid to its performance.

In the design of this type of ventilation grill, special technological holes must be provided for its fastening at the place of destination.

This is done with the help of ordinary self-tapping screws. For a stronger fixation of the ventilation grill, equipped with a non-return valve, experts recommend using a mounting foam.

All the areas of the intake opening of the hood that is not blocked by the device are lapped.

Before installing this type of ventilation grill, it is recommended to check the position of the operating valve.

There is a risk that the check valve may be in the open position and, if necessary, simply does not work.
