Greenheck EVH-602D Installation Manual
Miami-Dade Qualified
Wind-Driven Rain Louver
Application and Design
EVH-602D is an extruded aluminum stationary louver designed
to protect air intake and exhaust openings in building exteriors
specifically for applications requiring extremely high structural
design loadings. Design characteristics meet the performance
criteria established by the Florida Building Code and MiamiDade County. Tested in accordance with and passes TAS 201
(Large Missile Impact), TAS 202 (Uniform Static Air Pressure),
TAS 203 (Cyclic Wind Loading) and TAS 100A (Wind-Driven Rain)
with optiononal VCD-40 damper. EVH-602D may be installed
in a location where the space behind the louver is designed to
accept water penetration and houses water resistant/water proof
equipment, components or supplies. Qualified for installation within
concrete/masonry, steel stud, structural steel or wood framed
building conditions.

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.

Seal. The ratings shown are based on
tests and procedures performed in
accordance with AMCA Publication 511

AMCA Certified Ratings Program. The
AMCA Certified Ratings Seal applies to
air performance, water penetration, and

Model EVH-602D resistance to airflow (pressure drop)
varies depending on louver application (air intake or air
exhaust). Free area velocities (shown) are higher than average

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-602D 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.
