The VL-VF2 is specifically designed to deliver exceptional rain defence and low pressure loss, making it ideal for environments requiring robust ventilation solutions. The vertical blade design enhances airflow while using gravity and surface tension to direct water away, ensuring reliable performance in adverse weather. With a shallow 100mm frame, it integrates easily into various facades elements including window joinery. Unlike horizontal louvres, the vertical configuration allows low-height installations while preserving active ventilation capacity. Commonly used in data centres, dairy factories, and apartments.
