Greenheck EVH-602 Installation Manual
Wind-Driven Rain Louver
Vertical Blade
Application and Design
EVH-602 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 vertical rain resistant blades to
provide maximum resistance to wind driven rain in even the
most extreme weather conditions. The EVH-602 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.

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 EVH-602 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.
