This model of ventilation grilles is intended for installation at the ends of ventilation ducts. It is used for installation in residential, residential-business and smaller industrial premises. The slats are made of sheet metal with a thickness of 0.3 mm. The movable slats open when the air flows through the louver. When the air flow stops, the slats close and prevent air flow in the opposite direction.
It is used for mounting on the external wall (facade)
Cold-rolled sheet metal in EN-DC 04, AISI-G1008, GOST1050-08Yu standard with a thickness of 0.5 mm and subsequently surface protected is used to make the frame.
The slats are made of prochromic, non-magnetic, acid-resistant sheet metal in standard EN-X5CrNi18-10, AISI-304, GOST1050-07H18N10, thickness 0.3 mm
The inlet is made of cold-rolled sheet metal in standard EN-DC 04, AISI-G1008, GOST1050-08Yu with a thickness of 0.5 mm and subsequently surface protected
The surface protection applied to this product is:
– plasticization: High-quality protection of metal parts from corrosion is achieved with a paint coating. The product has a smooth and shiny surface (>80%). By plasticizing, a protective layer with a thickness of 60-80 μm is obtained, stable in the temperature interval -40 to +200ºC. Standard products are made in white and brown (on special request, other colors are possible).
There are several ways of installing this type of grating:
1. By means of a screw connection through the opening on the grid body
2. installation in the pipe
3. assembly by means of mortar or some other binding agent
The entire production process is covered by certificate AT-06086/0
