Wind-Driven Rain Louver

Horizontal Blade

Application and Design

EHH-401 is a Wind-Driven Rain louver designed to protect air intake and exhaust openings in building exterior walls that are sensitive to direct water penetration. Design incorporates a drainable head member and horizontal rain resistant blades to provide maximum resistance to wind driven rain in even the most extreme weather conditions. The EHH-401 is an extremely efficient louver with AMCA LICENSED PERFORMANCE DATA enabling designers to select and apply with confidence.

The AMCA Water Penetration Test provides a method for comparing

various louver models and designs as to their efficiency in resisting the penetration of rainfall under specific laboratory test conditions.

The beginning point of water penetration is defined as that velocity Model EHH-401 resistance to airflow (pressure drop) varies depending on louver application (air intake or air exhaust).

Free area velocities (shown) are higher than average velocity through the overall louver size. See louver selection

information.

where the water penetration curve projects through 0.01 oz. of water

(penetration) per sq. ft. of louver free area. *The beginning point of

water penetration for Model EHH-401 is above 1250 fpm free

area velocity. These performance ratings do not guarantee a louver

to be weather-proof or stormproof and should be used in combination

with other factors including good engineering judgement in selecting

louvers.
