Miami-Dade Qualifi ed
Drainable Blade Louver
Application and Design
ESD-635D 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. The ESD-635d is an AMCA CERTIFIED
LOUVER enabling designers to select and apply with
confidence. Design characteristics meet the performance
requirements established by the Florida Building Code and
Miami-Dade County. Tested in accordance with and passes
TAS 201 (Large Missile Impact), TAS 202 (Uniform Static Air
Pressure) and TAS 203 (Cyclic Wind Loading). ESD-635D may
be installed in locations 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.

Water Penetration (Standard Air - .075 lb./ft.3)
Test size 48 in. x 48 in. Test duration of 15 min.
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 .01 oz. of water
(penetration) per sq. ft. of louver free area. *The beginning point of
water penetration for Model ESD-635D is 1077 fpm free area
velocity. These perfor mance 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.
*AMCA licensed performance data shown herein pertains only to the louver
and does not include effects of the factory attached VCD-40 damper.
