Roller shutter aluminum anodized stainless steel - closed profile type 25x180 ZAALST-1,8/25/180

Collapsible grille – functionality and aesthetics in heating and ventilation systems

The aluminum anodized collapsible grille is a practical solution for ventilation and heating ducts. Made of a closed profile with dimensions of 25x180 mm, it is an additional equipment element for popular models of VK, VKN heaters and CVK fan coil units. Its construction allows for regulating the airflow, and the material ensures durability and corrosion resistance.

Construction and application

The grille consists of aluminum slats connected in a collapsible structure. Sleeves made of black PVC stabilize the whole and facilitate assembly. The distance between the rungs is 13 mm, which ensures optimal airflow without excessive restriction of visibility. Thanks to the closed profile, the grille is more resistant to mechanical damage than models with an open profile.

Collapsible grilles are primarily used in:

• Mechanical ventilation systems
• Channel heaters (VK12, VK15, VKN1, VKN2 SILENT, VKN5, SVKN1, VKN5P)
• Fan coil units (CVK2, CVK4, CVK2P, CVK4P)
• Underfloor heating installations (as a finishing element)

Advantages of the aluminum anodized collapsible grille

• Durability: Anodized aluminum is resistant to corrosion and mechanical damage, which guarantees a long product life. Anodizing is a chemical process that increases the hardness of the aluminum surface.
• Aesthetics: The stainless steel finish gives the grille an elegant look that blends well with various interior designs.
• Airflow regulation: The collapsible design allows for easy adjustment of the amount of air flowing through the channel.
• Easy installation: The grille is equipped with PVC sleeves to facilitate mounting to the ventilation duct or heater.
• Versatility: Fits a wide range of VERANO heaters and fan coil units, as well as other manufacturers with compatible dimensions.
• Resistance to weather conditions: Anodized aluminum tolerates variable humidity and temperature conditions.

Thanks to the combination of functionality and aesthetics, the collapsible grille is an ideal solution for both professional installers and end-users looking for a durable and elegant finishing element for a heating or ventilation system.
