Example of use:
The VD roof fan provides continuous basic ventilation. When VOC levels rise during periods of increased occupancy, the sensors register the change and send a signal to the EUR control system, which adjusts the ventilation performance accordingly. This enables demand-based fan control and supports efficient operation. An effective sound insulation concept combining base and roof fan attenuators also helps keep noise levels low in occupied spaces and around the fan installation area.
