Fixed rainproof louvers are ventilation and rainproof devices with fixed, non-adjustable blade angles. Their design must simultaneously meet structural strength, rainproof performance, and ventilation requirements. They are widely used in ventilation openings, equipment rooms, and exterior wall decorations in industrial, commercial, and civil buildings. The dimensions of fixed rainproof louvers must match the installation scenario (e.g., pre-drilled openings in walls, equipment ventilation openings).
