1. Overview of Weather-proof Louver Air Outlet
1.1
The weather-proof louver air outlet is a dedicated HVAC ventilation terminal device for exterior walls, widely installed on building outer walls, machine rooms, basements, and equipment shafts. It is applied for outdoor fresh air intake and indoor exhaust air ventilation. Featuring professionally designed inclined rain-proof blades, the grille effectively blocks rainwater, sand, debris, and birds from entering ventilation ducts and indoor spaces while ensuring smooth and stable air circulation. It integrates multiple functions including ventilation, rain protection, dust prevention and external protection. Adopting an all-mechanical structure, the product is sturdy, durable, and requires no power supply for long-term stable operation. A stainless steel insect screen is optional to block insects and fine particles, perfectly suitable for various civil and industrial ventilation scenarios.
