Rain-Proof Louvered Air Vent

Rain-proof louvered air vents are protective air supply devices installed on building exterior walls or at ventilation openings. The louvers are designed with a 45° angle; the outer layer is densely arranged to form a rain barrier, while the inner layer allows for adjustment of airflow direction. Their core function is to block rainwater intrusion through the slope and spacing of the louvers while allowing air to circulate, thereby combining ventilation and rain protection. Typically made of aluminum alloy (with an anodized finish) or stainless steel, these units are corrosion-resistant and wind-pressure-resistant, making them suitable for outdoor applications such as air conditioner outdoor unit enclosures, ventilation openings in equipment rooms, and factory exterior walls.
