Perhaps today the most popular products from the elements of ventilation systems are ventilation grilles. Many underestimate their importance in ventilation systems. But in fact, in addition to the fact that they are an element of decor, they also contribute to air circulation in our rooms, as well as prevent the entry into the ventilation system of insects, garbage, dust and m.D.
To date, it is not difficult to choose a grill suitable in style to the existing interior design, which from a technical point of view will correspond to the selected type of room. It will not be an exaggeration, if we say that the correct functioning of the entire ventilation system depends on the quality of the ventilation.
What is the purpose of the ventilation bars?
Ventilets are of different types. First of all, they are divided into industrial and household. There are grilles for internal and outdoor installation. They are adjustable and not adjustable. Different color gam and shapes — round, rectangular and square. According to the material of manufacture — metal (often steel or aluminum) or plastic.
Lattices have a variety of structures, which is explained by the place of installation and functionality. These include:
One -row and two -row;
Perforated;
Inertial ventilations operating on the principle of a check valve in the case of a system stop;
Pepper, slit and cellular (regulating the flow of air in the room);
External ventilations;
Gratings with mobile blinds.
Ventilation grilles external pH are traditionally located outside the house. They are designed to supply and remove air in ventilation, air heating and air heating systems. Structurally, the lattice consists of a frame and motionlessly fixed louluses of S- figurative aerodynamic shape. They are made of light aluminum alloy and have a strong design.
RN have the following advantages:
good moisture repellent properties;
low pressure losses;
resistance to pollution.
In some cases, external ventilation grilles also have a heating function that prevents the formation of ice.
Ventilation grilles with RS-G blinds-elements of both supply and exhaust ventilation systems. Blinding vents are designed for use in those places where transparency is undesirable. Such lattices are used mainly on the facades of buildings and structures and hide ventilation openings.
RN have the following advantages:
strength;
durability;
good performance;
the possibility of painting in the desired color and t.p.
When choosing a ventilation grill, it is necessary to determine the direction of the flow of supply air in one, two, three or four sides, t. To. Depending on their design, they form compact, flat, incomplete fan or other types of jets.
Such a wide range of purpose and use of the ventilations is explained by their indisputable advantages!
