Efficient Air Control with the VKS-ALU 35

The VKS-ALU 35, automatic closure flap by CasaFan is the ideal solution to prevent cold air, dirt, and insects from entering your ventilation openings. This closure flap opens automatically through the airflow of the fan and closes due to its gravity mechanism. Made of anodized aluminum, it not only offers an appealing look but also high resistance to weather influences.

The VKS-ALU series includes various nominal diameters, including the variants 200 mm, 250 mm, 300 mm, 350 mm (this page), 400 mm, 450 mm, 500 mm, 550 mm, 600 mm, 650 mm, and 700 mm. All variants share the same high-quality features, but the nominal diameter varies, which is crucial for the application. The VKS-ALU 35 is particularly suitable for applications with higher airflow speeds over 10 m/s and offers a long service life due to its special construction.
