Designed for reliable rain defence, the VL-104D features a single bank drainable blade system with vertical gutters integrated into a flanged perimeter frame. This efficient design ensures water is directed away from the blades and ejected to the panel's front. Constructed from extruded aluminium, it supports both intake and exhaust ventilation, making it ideal for plant rooms, schools, commercial, and industrial applications.
