Slotted ventilation grilles. Slotted

Among other products we produce, we advise you to pay attention to AirGrille slotted grilles, which are integral elements of the design of ventilation, heating and other systems that ensure a comfortable microclimate and clean indoor air. With their help it is easy to control the volume of incoming or outgoing air flow.

Slotted grilles are made of stainless or carbon steel (with a decorative anti-corrosion coating) steel, as well as brass. Our company produces gratings of all sizes. You can order non-standard products from us (for original design and design solutions). You can also buy standard slotted grilles from us.

Slot grill design

The design of the slotted grille is not too complicated. It is a rigid frame with flanges directed inward, to which a front (decorative) frame is welded. Slats are attached inside the frame (strictly along the normal or at an angle), forming blinds, between which there are gaps. Blinds provide air flow, while simultaneously protecting the air supply system from foreign elements getting inside it. Thus, the volume of air passing through the slot grille is controlled.

To prevent the internal space of the air duct from being visible through the opening of the slot grille, it can, at the customer’s request, be equipped with a perforated fine-mesh black mesh.

The grille is attached to vertical surfaces with self-tapping screws, for which there are special eyes in the frame, located so as to ensure that the fasteners are not visible from the side. To install slotted grilles on horizontal surfaces (countertops, window sills, etc.), you can use silicone-based plumbing adhesives.

Grates made of steel are coated with a layer of polymerizing powder paint. The color is selected according to the RAL catalogue. This coating reliably protects the metal surface from corrosion and harmful influences, while simultaneously giving the product an attractive appearance, and thereby ensuring the overall harmony of a single style of the interior of the room.

Scope of application of slotted gratings

The scope of application of slotted gratings is very extensive. They are installed in different ventilation systems, both exhaust and supply and exhaust, ensuring uniform air flow. Also, they are necessarily included in climate control systems based on duct air conditioners, which are often equipped in residential (apartments, hotel rooms, private houses, etc.) and office premises.

The slot grille can be built into almost any horizontal or vertical surface where the air duct is connected (wall, door, window sill, etc.).

Evaluate the variety of gratings we produce, both in terms of materials used and design features, And appearance, you can familiarize yourself with the contents of our catalogue.

Our production will quickly produce the required number of slotted gratings of any size, type and shape (T-shaped or corner, among others), both for external and internal placement with millimeter precision.

Exhaust grilles are designed to remove air from rooms.

Supply slot grilles are designed to supply air to rooms for various purposes using ventilation and air conditioning systems, including those with variable air flow. Slotted supply grilles ensure stability of the supply air stream in the range of changes in volumetric flow rates from 100% to 25%, including in cooling mode.

Slotted grilles are a structure made of aluminum profile with a number of slots from 1 to 6. In each slot of the supply grilles RShch-rzh, two regulators are installed, which act as a flow divider and an air flow regulator, as well as two guide blinds, when rotated at an angle α from 0° to 45° the direction of the supply flow changes from vertical to horizontal. When the length of the grille is more than 1 m, the blinds are made as composites.

It is possible to arrange supply slot grilles without rotating blinds RShch-r, but with a regulator (in this case, the direction of the supply flow is not regulated) or without a regulator RShch-zh, but with rotating blinds. The gratings can be supplied with sidewalls (RShchB) and without them (RShch).

Structurally, exhaust grilles differ from supply grilles in the absence of both a regulator and rotary blinds.

The standard color of painted grilles is white (RAL 9016). Palette of non-standard painting colors according to the RAL catalogue.

Characteristics of ventilation grilles

Standard sizes of gratings: L (length) from 100 mm to 2000 mm; H (height) from 49 mm (1 slot) to 244 mm (6 slots), pitch 39 mm. Coefficient of open cross-section of supply grilles Kzh.s. = 0.25; exhaust grilles - Kzh.s. = 0.60.

Overall and connection dimensions

p - presence of a regulator; g - the presence of guide blinds; n is the number of grating slits.

When calculating the dimensions of adapters for RP grids, it is necessary to use the formula H+1*L+3.
For example: Grille RShch-1rzh 49*300 – adapter size: 50*303 mm.

When calculating the dimensions of adapters for RSB gratings, it is necessary to use the formula H+1*L+13.
For example: Grille RShchB-2rzh 88*400 – adapter size: 89*413 mm.

The vent grilles will be successfully combined with other decorative elements: if an ornament was previously used, then the craftsmen will exactly repeat it on the structures.

Moreover, no matter what type of carved pattern: the grille will perform its main function - air inflow and outflow - 100%!

The production of metal dampers is carried out on technologically advanced modern machines, so nothing is impossible for us! Tell us about your ideas and wishes, and we will implement them in no time!

Slotted ventilation grilles can be made in any shade from the Ral palette, but if your imagination is not limited by the color standard, then we are ready to listen to your wishes and do exactly what you need!

The product comes with a special mounting kit, which includes self-tapping screws made in the same style and color scheme, the same as the main design. If you wish, you can install the screens yourself. If you want to save your time and effort, then order the services of our masters.

Classification of slotted gratings

Doors made in the shape of the letter “L” create additional volume and at the same time hide the ventilation hole. Options with G-profile possible different sizes, as well as application in the form of a prefabricated structure without a base between the segments.

They have all the same advantages as grilles with an L-profile; in addition, they are often used for the construction of floor ventilation grilles. The product is very durable: it will support the weight of a person or an entire chair without deforming or changing shape. The segments can be installed in any direction: longitudinally or transversely to the elongated side of the grille.

T-shaped segments are used here, with one side located at an angle. This arrangement of the blinds helps the air flow in the right direction. However, externally, gratings with a T-shaped profile are not similar to similar products with inclined sashes.

Where are slotted gratings used?

Slot-type grilles can be built into almost any surface, be it vertical or horizontal, where the air duct has an outlet (countertops, window sills, doors, walls and others). They are resistant to temperature changes, do not absorb moisture and do not deform.

Production time for slotted gratings

Our production of slotted gratings takes 3-10 working days. Please contact our manager by phone for exact production times. They depend on a number of factors:

required number of gratings
complexity of grating design
difficulty in installing finished products
type of raw material
