Application and Design
EVH-501D is a Florida Product Approved and Miami-Dade Qualified stationary vertical
blade wind driven rain extruded aluminum louver designed to protect air intake and exhaust
openings in building exterior walls. EVH-501D is tested in accordance with AMCA 500-L Air
Performance, Water Penetration and Wind Driven Rain. EVH-501D is tested in accordance
with AMCA 540 Test Method for Louvers Impacted by Wind Borne Debris (Basic
Protection, Missile Level D and Enhanced Protection, Missile Level E). EVH-501D is tested
in accordance with AMCA 550 Test Method for High Velocity Wind Driven Rain Resistant
Louvers. EVH-501D is licensed to bear the AMCA seal allowing design professionals to
select and apply with confidence. EVH-501D is tested and qualified per the following Florida
test protocols: TAS 201 (Large Missile Impact), TAS 202 (Uniform Static Air Pressure) and
TAS 203 (Cyclic Wind Loading). Per Miami-Dade EVH-501D may be installed in locations
where the room behind the louver is NOT designed to drain water penetrating into the
room or the room will house non-water resistant or water proof equipment, components or
supplies.

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-501D 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.
Airflow Resistance (Standard Air - �075 lb/ft
3
)
Model EVH-501D 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. (Test Figure 5.5-6.5)
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.
