• 【Durable and Corrosion-Resistant】The wall vent is constructed from a single piece of 304 stainless steel with a high-temperature baked paint finish, ensuring robust durability. It withstands outdoor weathering, grease fumes, and corrosion, making it suitable for long-term use in diverse environments.
• 【Enhanced Ventilation】The circular louvered grille with a triple-vent structure and widened airflow guides increases ventilation area. It efficiently expels cooking fumes, moistures, and exhaust gases, addressing issues of poor airflow and clogging common in traditional vents.
• 【Reduced Backflow Risk】The snap-ons top cover with bottom vent design expands rain protection, minimizing rainwater and snowmelt backflow to keep ducts and indoor environments dry and clean.
• 【High-Density Protection Screen】Built-in stainless steel mesh with fine, uniform openings blocks birds, rodents, and insectss from entering ducts without compromising ventilation, reducing clogs and hygiene risks.
• 【Versatile Installation】Available in multiple diameters (70mm-200mm) and four colors (black, white, gray, yellow). Compatiblewith range hoods, fresh air systems, bathroom exhaust fans, etc. Simple installation complements exterior wall aesthetics.
