The ventilation grille: description, application

Air-circulation System provided for a total construction of special lattices, which provide dispersion of the output streams. In terms of functionality it's not the most important element of the whole complex, but without it difficult. First, this component, depending on the type, allows to manage the capacity of opening, and secondly, the ventilation grille plays a decorative role. This also applies to items placed on the front part of the facade, and models that adorn the outputs of the channels inside.

The Use of ventilation grilles

The Main purpose of this kind of products is in the structural completion of the ventilation shaft. The grid used in the provision of such systems of industrial buildings, private homes, factories and offices. Of course, the list of functions they may be different. In some cases, in the first place is the problem of dispersion, and others – protection from external influences. For example, the grid metal ventilation often used as an element of protection, preventing not only the passage of debris and large objects.

We should also mention the function of the lattice in the system of natural ventilation. In this case it would depend on the volume of air that will enter the house. When choosing items to equip such mines takes into account not only the size but also design features. In particular, the ventilation grille can be a different device edges.

Classification at the place of installation

The modern market presents a model for indoor and outdoor installation. Products of the first category is used for the equipment of the channels directly on the premises. This may be ventilation grids plastic in the form of deflectors or shutters. Such devices are small size and distinct design advantages.

Grille for installation on the street side most often are made of metal, as in their range of tasks includes said protection from leaves, dirt, small stones, etc. To include the functional model with the presence of the check valve. Using these devices can provide unidirectional air movement. Particularly relevant ventilation grille with non-return valve in the winter, as it can help to release the waste mass and prevent passage of cold air.

Classification

There are two basic types of construction of ducts – fixed and adjustable. In the first case is the simplest products that can be used when equipped with any air duct. Reliability and durability-the main advantages of such a ventilation grate. The price of such products usually is 100-150 rubles, while a lot of plastic model no more than 50 RUB. the Second type of the design – adjustable. This embodiment is characterized by functionality, as it allows not just to protect mine, and to manage its bandwidth. It is very convenient when operating in regions with variable climate. There is no need to completely close the input channel due to bad weather – simply the best way to change the position of the ribs.

Cello metal

The Metal because of the obvious advantages is more often used in the manufacture of grids for the massive air ducts that are equipped with manufacturing plants and business premises. Has best strength sheet steel treated with special anticorrosive coatings. These components protect the exhaust passages and from penetration of rodents. In equipping private homes are usually applied aluminum grilles are also covered compositions from rust. These products lose the steel equivalent in strength and durability, but provide a more attractive appearance. You could say it's a compromise between the rough steel structure and the aesthetic appearance of a plastic grid.

Features plastic gratings

Choosing between plastic and metal, do not think that the first material is absolutely useless from the point of view of mechanical protection. Manufacturers use in the manufacture of models for high strength materials, so you can count on long life. And this is not to mention their resistance before the corrosion, ease of installation and neat appearance. In addition, air vents plastic are cheaper and come in a greater variety of shapes and sizes. If you plan a complex system with non-standard duct section, the first appeal to this segment. However, for large industrial mines air ducts are much preferable to all the same metal.

Dimensions ventilation grills

Projects ventilation systems recently moving away from standard sizes. Those private houses, as a rule, imply development of individual planswhich further runs the device communications 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 the size 58х58 mm, 150x150 mm, etc. At the same meeting and rectangular models 170х80 mm. most popular size for private use should include 204х204 mm and 300x300 mm. of Course, you can find other sizes or even order for custom-made lattice.

Conclusion

Usually in the construction process, auxiliary components and accessories has been given little attention. Sometimes it is not required if this element performs a purely decorative role – change the texture or texture at any time. But it happens that the additional components have a significant impact on the overall process of operation of a particular design. To detail true ventilation grate. The price of 100-150 rubles. seems insignificant, but it does not follow that the function of this element is not so important. From the grid to a large extent depends on the quality of air. If we are talking about equipment of premises, installation of the ventilation channel also determines the characteristics of the microclimate. And this applies not only to lattices, which are installed on the street the air duct. There is a separate category of products designed to ensure the ventilation between the different areas inside of apartment or house.
