NCC -Weatherproof Louver  For the most diverse applications, large-sized external weather louvers can also be provided. External weather louvers are installed externally as air delivery devices for fresh air and exhaust air in air conditioning systems. They are installed on the exterior wall. Their leaves are arranged very narrow, which can effectively resist the direct entry of rainwater, as well as resist leaves and birds. Under certain unfavorable conditions, such as heavy rain, a small amount of water vapor may enter together depending on the airflow speed. This is why the airflow velocity in the fresh air opening should not exceed 2-2.5 m/s. NCC louvers have been proven to be true strength, withstanding rigorous testing, providing excellent rainproof performance  excellent airflow characteristics。
