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).
