Modern Aluminum Circular Rainproof Louvre Wind Cap Villa Attic Ventilation Hole Exhaust Port Window Grille for Wind Exhaust
The pressed rain-proof louver does not have the function of rain prevention in its design. Even when it is tightly closed, rainwater can still enter through the gaps. The rain-proof louver is used in machine rooms or other public places that require ventilation, rain prevention, heat insulation, and regulation of air flow. It consists of rain-proof blades with water collection grooves, side frames with drip trays, and streamlined regulating blades. Even in heavy rain, the rain-proof louver can effectively prevent rainwater from entering the room, and no water curtain will form on the windward side of the entire rain-proof louver, thus fulfilling the normal design ventilation requirements.
