Ventilation lattice: description, application

Air exchange systems provide in the general design the presence of special grids, which ensure the dispersion of the outflows. In terms of functionality, this is not the most significant element of the whole complex, but without it it is difficult to manage. First, this component, depending on the type, allows you to control the throughput of the opening, and secondly, the vent grid plays a decorative role. This applies to the elements located on the front of the facades, and to models decorating the outputs of channels inside the premises.

Application of ventilation grids

The main purpose of products of this kind is the structural completion of the ventilation shaft. Lattices are used in the supply of such systems of industrial buildings, private houses, businesses and offices. Of course, the list of functions may differ. In some cases, the problem of dispersion comes first, while in others it is protected from external influences. For example, metal ventilation grilles are often used precisely as an element of protection, preventing not only the passage of debris, but also large objects.

Separately it is worth noting the function of the grid in the system of natural fresh air ventilation. In this case, it depends on it the volume of air that will penetrate the house. When selecting parts for equipping such mines, not only dimensions, but also design features are taken into account. In particular, the vent grid may have a different fin arrangement.

Classification in the place of installation

In the modern market, models for indoor and outdoor installation are presented. Products of the first category are used to equip the channels directly in the premises. These can be plastic ventilation grids in the form of deflectors or blinds. Such devices differ in their small size and expressed design advantages.

Lattices for installation on the street side are most often made of metal, because their range of tasks includes the mentioned protection from leaves, dirt, small stones, etc. The most functional are the models with the presence of a non-return valve. With the help of such devices, unidirectional air movement can be provided. Especially the actual ventilation grille with a non-return valve in the winter, since with its help it is possible to discharge waste materials and prevent the passage of cold air.

Classification by design

There are two main types of construction of ventilation grids - stationary and adjustable. In the first case, these are the simplest products that can be used to equip any air ducts. Reliability and durability are the main advantages that such a ventilation grill possesses. The price of similar products is usually 100-150 rubles, although a lot of plastic models are not more expensive than 50 rubles. The second type of construction is adjustable. This option is notable for its functionality, since it allows not only to protect the mine, but also to control its throughput. It is very convenient for operation in regions with a changeable climate. There is no need to completely close the channel entrance due to bad weather - it is enough to change the position of the ribs in the most favorable way.

Ventilating lattices metal

Metal due to obvious advantages is often used in the manufacture of grids for massive air ducts, which are equipped with industrial enterprises and utility rooms. The greatest strength is in sheet steel, treated with special anti-corrosion coatings. Such components protect the exhaust passages from penetration of rodents. In equipping private houses, aluminum ventilation grilles, also coated with rust-containing compounds, are usually used. Such products lose to steel analogues in strength and durability, but they provide a more attractive appearance. We can say that this is a compromise between the rough steel structure and the aesthetic appearance of the plastic grille.

Features of plastic gratings

Choosing between plastic and metal, do not think that the first material is completely useless in terms of mechanical protection. Manufacturers use high-strength materials in the manufacture of such models, so you can expect a long service life. And this is not to mention their resistance to corrosion, ease of installation and neat appearance. In addition, the plastic ventilation grilles are cheaper and presented on the market in a larger assortment of shapes and sizes. If a complex air duct system with a non-standard cross-section is planned, then first of all they turn to this segment. True, for large industrial shafts of air ducts, metal is much more preferable.

Dimensions of ventilation grilles

Projects of ventilation systems have recently departed from standard sizes. The same private homes, as a rule, assume the development of individual plans, which further carries out the construction of communication networks. Accordingly, in the market you can find a huge selection of products with different parameters. In the initial category, the ventilation grille is represented by dimensions 58x58 mm, 150x150 mm, etc. At the same time, rectangular models in the format of 170x80 mm are also encountered. The most popular sizes for private use are 204x204 mm and 300x300 mm. Of course, you can find other sizes or even make an order for the individual production of the grate.

Conclusion

Usually, during construction, the least attention is paid to auxiliary components and accessories. Sometimes it is not required, if this element performs a purely decorative role - you can change the texture or texture at any time. But it happens that the additional components have a significant influence on the overall operation of a particular design. The ventilation grille also belongs to such details. The price is 100-150 rubles. Seems to be insignificant, but it does not follow from this that the function of this element is not so important. The quality of the air exchange depends to a large extent on the grating. If we are talking about the equipment of living quarters, the device of the ventilation duct also determines the characteristics of the microclimate. And this applies not only to the grilles, which are installed on the street air outlets. There is a separate category of products designed to provide ventilation between different rooms inside the apartment or at home.
