For the most diverse applications, NCC wind and rain louvers can also provide large-sized external wind and rain louvers. External wind and rain louvers are air delivery devices installed on the outside, used 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 the leaves and birds. Under certain unfavorable conditions, such as heavy rain, a small amount of water vapor may enter together depending on the speed of the airflow. That's why the airflow velocity in the fresh air opening should not exceed 2-2.5 m/. NCC louvers have been proven to be truly powerful, withstanding rigorous testing, providing excellent rainproof performance and excellent airflow characteristics.

NCC Weatherproof Louver Specification Parameter Table

The FYL150RS series of double row louvers has a high rainwater penetration rate of Class A, with a speed of 0.5m/s,
And the airflow level is 3.
The single row louver FYL100S series has excellent airflow rate and airflow level of 2.
NCC wind and rain louvers all have BSRIC test reports. According to the louvers of each project
The size of the pipe segment provides free area calculation.

Weatherproof louver test: BSRIA/AMCA test in the UK/AMCA test in the US

All louver systems of NCC have been tested by BSRIA or AMCA, and industry standards are developed by BSRIA (Building Services Research and Information Association). HEVAC adopted BSEN13030:2001 as a UK and European standard in 2001.
