At the 50-mph wind velocity and 8 in./hr simulated rainfall AMCA point, the louver provides a B Wind Class rating with a 95% effectiveness ratio. The ECD-445 is also AMCA certified for air performance and water penetration. It has a free area of 43.3%, a beginning point of water penetration above the 1,250 fpm maximum certified by AMCA, and only a 0.15 in. pressure drop at 860 fpm.
