Roller shutter aluminum anodized stainless steel - closed profile type 14x125 ZAALST-1,8/14/125

Collapsible grille – functionality and aesthetics in heating and ventilation systems

Collapsible grille made of anodized aluminum is a practical solution for ventilation and heating ducts. It is characterized by a solid construction with a closed profile, which ensures its durability and resistance to damage. It is an additional equipment element for popular models of VK, VKN and CVK fan coil units – the grille selection should be considered at the ordering stage.

Construction and materials

Made of anodized aluminum, the grille combines lightness and durability. Anodizing is a process that increases the material's resistance to corrosion and abrasion, and also gives it an aesthetic appearance. The closed profile further strengthens the structure, making it more resistant to deformation. PVC sleeves in black color provide an aesthetic finish and facilitate installation. The pitch of the slats is 13 mm, which ensures optimal airflow.

Application and compatibility

Collapsible grilles are widely used in heating and ventilation systems, both in residential and commercial buildings. They are particularly recommended for:

• VK12, VK15, VKN1, VKN2 SILENT, VKN5, SVKN1, VKN5P channel heaters
• CVK2, CVK4, CVK2P, CVK4P fan coil units
• Ventilation systems requiring airflow regulation

Thanks to the possibility of collapsing or expanding the grille, its size can be easily adjusted to the needs of a given room or installation. This solution is particularly useful in the case of ducts with variable width or in situations requiring periodic airflow regulation.
