Greenheck EHH-601 Installation Manual

Wind-Driven Rain Louver

Horizontal Blade

Application and Design

EHH-601 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-601 is an AMCA
CERTIFIED LOUVER enabling designers to select and apply
with confidence.

Weather louvers shall be classified by their ability to reject simulated rain. The table shows different classifications based on the maximum
simulated rain penetration per square meter (square feet) of louver. Water penetration rating at a given louver face velocity is determined by
the water penetration while the louver is subjected to a selected simulated rainfall rate and wind velocity.

Free Area Velocity

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
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-601 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.
