Air exchange systems provide for the presence of special gratings in the overall design, which ensure the dispersion of outgoing flows. In terms of functionality, this is not the most significant element of the entire complex, but it is difficult to do without it. Firstly, this component, depending on the type, allows you to control the throughput of the opening, and secondly, the ventilation grill also plays a decorative role. This also applies to the elements located on the front of the facades, and to the models decorating the exits of the channels inside the premises.
Application of ventilation grilles
The main purpose of products of this kind is the structural completion of the ventilation shaft. Lattices are used when supplying industrial buildings, private houses, enterprises and offices with such systems. Of course, their list of functions may be different. In some cases, the task of dispersion comes first, and in others, protection from external influences. For example, metal ventilation grilles are more often used precisely as a protection element that prevents not only the passage of debris, but also large objects.
It is worth noting the lattice function innatural ventilation system. In this case, the volume of air that will enter the house depends on it. When choosing a part for equipping such mines, not only dimensions are taken into account, but also design features. In particular, the ventilation grille may have different arrangement of ribs.
Classification by location
On the modern market there are models for indoor and outdoor installation. Products of the first category are used to equip channels directly in the premises. These can be plastic ventilation grilles in the form of deflectors or blinds. Such devices are distinguished by their small size and pronounced design advantages.
Grates for outdoor installation are most often made of metal, as their range of tasks includes the above-mentioned protection against leaves, dirt, small stones, etc. The most functional are models with a check valve. With the help of such devices it is possible to provide unidirectional air movement. A ventilation grill with a non-return valve is especially relevant in winter, as it can be used to release waste mass and prevent the passage of cold air.
Classification by design
There are two main types of ventilation grilles - fixed and adjustable. In the first case, these are the simplest products that can be used to equip any air ducts. Reliability and durability -the main advantages that such a ventilation grill has. The price of such products is usually 100-150 rubles, although there are many plastic models no more than 50 rubles. The second type of design is adjustable. This option is distinguished by functionality, as it allows not only to protect the mine, but also to control its throughput. This is very convenient when operating in regions with a changeable climate. There is no need to completely close the channel inlet due to bad weather - it is enough to change the position of the ribs in the most advantageous way.
Metal ventilation grilles
Metal, due to its obvious advantages, is more often used in the manufacture of gratings for massive air ducts, which are equipped with industrial enterprises and utility rooms. Sheet steel treated with special anti-corrosion coatings has the greatest strength. Such components protect the exhaust passages from the penetration of rodents. In the equipment of private houses, aluminum ventilation grilles are usually used, also coated with anti-rust compounds. Such products lose to steel counterparts in strength and durability, but they provide a more attractive look. It can be said that this is a compromise between the rough steel structure and the aesthetic appearance of the plastic grille.
Features of plastic gratings
When choosing between plastic and metal, do not think that the first material is completely useless in terms of mechanical protection. Manufacturershigh-strength materials are used in the manufacture of such models, so you can count on a long service life. And this is not to mention their resistance to corrosion, ease of installation and neat appearance. In addition, plastic ventilation grilles are cheaper and are available on the market in a larger range of shapes and sizes. If a complex duct system with a non-standard cross section is planned, then this segment is first addressed. True, metal is still much more preferable for large industrial air duct mines.
Ventilation grille sizes
Projects of ventilation systems have recently moved away from standard sizes. The same private houses, as a rule, involve the development of individual plans, according to which the communication networks are subsequently installed. Accordingly, on the market you can find a huge selection of products with different parameters. In the initial category, the ventilation grille is represented by dimensions of 58x58 mm, 150x150 mm, etc. At the same time, there are also rectangular models in the format of 170x80 mm. The most popular sizes for private use include 204x204 mm and 300x300 mm. Of course, you can find other sizes or even order a custom-made grate.
Conclusion
Usually, during the construction process, auxiliary components and accessories are given the least attention. Sometimes it is not required if this element performs purelydecorative role - you can change the texture or texture at any time. But it happens that additional components have a significant impact on the overall process of operation of a particular design. These details include the ventilation grille. The price is 100-150 rubles. seems insignificant, but it does not follow from this that the function of this element is not so important. The quality of air exchange depends to a large extent on the grille. If we are talking about equipping residential premises, then the device of the ventilation duct also determines the characteristics of the microclimate. And this applies not only to grilles that are installed on outdoor air outlets. There is a separate category of products designed to provide ventilation between different rooms inside an apartment or house.
