VKS-ALU 40: Optimal Solution for High Airflow Speeds

The VKS-ALU 40, automatic closure flap is the perfect choice to prevent cold air influx and the entry of dirt, birds, and insects into your ventilation openings. This high-quality closure flap opens and closes automatically through the airflow of the fan, providing effective protection for your ventilation systems. Made of anodized aluminum, the flap is not only visually appealing but also durable and weather-resistant.

Compared to the VKS-ALU 20, which has a nominal diameter of 200 mm, the VKS-ALU 40 offers a nominal diameter of 400 mm. This variant is particularly suitable for applications with higher airflow speeds exceeding 10 m/s, making it the ideal solution for demanding ventilation requirements.

The installation of the VKS-ALU 40 is simple and quick with screws and dowels included in the package. It can be installed either horizontally or diagonally. The soft PVC seal ensures a quiet and vibration-dampening closing process, enhancing comfort in your spaces.

Here are some key similarities and differences of the VKS-ALU variants:

• Material: All variants are made of anodized aluminum.
