4" Deep Drainable Blade Louver

E4DS

is a 4" deep louver with a drainable blade feature to channel water away from the blades. This feature allows higher air intake velocities before entraining water. If your application is air intake, consider this or other drainable louvers first. If this louver will not handle your intake velocities, consider a deeper louver, a high perfomance louver, or a wind driven rain louver instead (E4DP, E6DP, E6WH).
