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.

The VL-50CM is a 50mm fine-bladed screening louvre that shares the same frame and concealed mullion system as the high-performing VL-2SD and VL-3SD products. While it is not designed for high rain defence, it features a low-pressure drop and is ideal for applications such as plant screens, exhaust louvres, and inactive sections of double and triple bank systems. Its design allows for large, seamless louvre banks without visible support structures, making it a cost-effective and visually consistent solution for apartments, offices, and plant enclosures.

The VL-77EX is designed specifically for exhaust applications, offering very low pressure loss to maximize airflow with minimal mechanical assistance. Its design prioritizes airflow performance over rain defence, making it ideal for use in sheltered environments, such as under canopies. Constructed from durable extruded aluminium, it provides reliable ventilation for mechanical systems where high rain protection is not required. Common applications include exhaust louvres in industrial and commercial settings.
