Core Advantages

Please confirm your wall/soffit duct opening dimension before ordering; periodic cleaning keeps stable ventilation efficiency. Our Round Weatherproof Louvre adopts 45° angled louver structure to effectively block rainwater ingress for outdoor exterior installation. Built-in fine insect mesh inside the vent grille stops dust, fallen debris and small creatures from going into ductwork, ideal outdoor exhaust ventilation accessory for residential and commercial renovation.

Easy Installation Instruction

Insert the round weatherproof louver into reserved wall, soffit or ceiling opening, fasten with self-tapping screws and seal edges with silicone sealant (Screws & sealant are NOT included in package). Wear protective gloves during installation to avoid surface scratch on aluminum finish.

Wide Application Scenarios

This waterproof aluminum exterior vent works well for bathroom, kitchen, garage, storage shed, office, RV and camper ventilation. It is an ideal replacement for aged, rusted original outdoor vent caps for home improvement and exterior soffit exhaust projects.

Important Note

Double-check opening size compatibility prior to installation; regular inspection and cleaning can extend service life and maintain optimal airflow performance of the round weatherproof louvre vent.
