• ♢ The ventilation grille is made of 304 stainless steel with a high-temperature baking paint process, making it rust-proof, corrosion-resistant, sturdy, and not easily deformed. It can withstand wind, rain, and oil fume erosion, and is not prone to aging even after long-term indoor and outdoor use, resulting in a longer service life.
• ♢ The wall-mounted vents feature a three-outlet structure with widened guide louvers, increasing the ventilation area, reducing wind resistance, and ensuring smoother exhaust. This quickly removes oil fumes, moistures, and exhaust gases, solving the problems of poor ventilation and easy clogging found in traditional vents.
• ♢ The button-shaped vents with covers and bottom openings effectively expand the rain protection range, reducing rainwater and snow backflow, preventings water accumulation in pipes and indoor seepage, and keeping the pipes and indoor environment dry and clean.
• ♢ The circular vents have built-in high-density stainless steel protective mesh with fine and uniform mesh openings. Without affecting ventilation, it effectively blocks birds, rodents, and mosquitoes from entering the pipes, reducing blockages and hygiene and safetys hazards.
• ♢ Ventilation and exhaust outlets are available in multiple diameters from 70 to 200 mm and in four colors: black, white, gray, and yellow. They are compatiblewith range hoods, fresh air systems, exhaust fans, and other equipment. Installation is simple and suitable for various scenarios such as kitchens, bathrooms, warehouses, and garages.
