Application and Design
EVH-660D 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-660D is tested
in accordance with AMCA 500-L Air Performance, Water Penetration and Wind
Driven Rain. EVH-660D 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-660D is tested in accordance with
AMCA 550 Test Method for High Velocity Wind Driven Rain Resistant Louvers.
EVH-660D is licensed to bear the AMCA seal allowing design professionals
to select and apply with confidence. EVH-660D is tested and qualified per
the following Florida test protocols: TAS 201 (Large Missile Impact), TAS 202
(Uniform Static Air Pressure), TAS 203 (Cyclic Wind Loading) and TAS 100A
(Wind Driven Rain). Per Miami-Dade EVH-660D 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-660D 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-660D 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.
