ESD-435
High Performance 35 o Drainable Blade
Application & Design
ESD-435 is a weather louver designed to protect air intake and exhaust openings in
building exterior walls. Design incorporates drain gutters in the head member and
horizontal blades to channel water to the louver side frames or jambs where water
is further channeled through vertical downspouts and out at the sloped louver sill. It
has 35 o blades and offers the most free area in the ESD line. The ESD-435 is an
extremely efficient louver with AMCA Licensed Performance Data enabling
designers to select and apply with confidence.

ESD-435
Louver Performance Data
Greenheck certifies that the louver shown herein is licensed to bear the AMCA Seal. The ratings
shown are based on tests and procedures performed in accordance with AMCA Publication 511
and comply with the requirements of the AMCA Certified Ratings Program. The AMCA Certified
Ratings Seal applies to air performance and water penetration ratings.
Airflow Resistance (Standard Air- 0.075 Ib/ft^3 )
in. wg
Model ESD-435 resistance to airflow varies
depending on louver application (air intake or air
exhaust). Free area velocities (shown) are higher
than the average velocity through the overall louver
size.
FREE AREA VELOCITY (FL/rain)
Water Penetration (Standard Air- 0.075 Ib/ft^3)
Test Size 48 in X 48 in - 15 min. test period.
OZ./SQ.FT.
FREE AREA VELOCITY (Ft/min)
The AMCA Water Penetration Test provides a method
for comparing vadous 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 fl oz of water (penetration) per ft^2 of
louver free area. *The beginning point of water
penetration for model ESD-435 is 1,151.00 flJmin free
area velocity. These performance ratings do not
guarantee a louver to be weatherproof or stormproof
and should be used in combination with other factors
including good engineering judgement in selecting
louvers.

SELECTION AND APPLICATION ESD-435
Application of any Louver involves selectin9 an airflow velocity through the louver free area (free area velocity in ) that produces an
acceptable pressure drop and for intake applications minimizes carry through of normally encountered rain water. No louver
manufacturer warrants their louver to prevent water penetration under all possible combinations of wind and rain. Water penetration
through Model ESD-435 begins at 1,151.00 ft/min free area velocity. Intake air louver selection using free area velocity below 1,151.00
fi/rain is recommended. Louver selection invloves the following two steps, and depending on given conditions, either step may come
first.
Select Free Area Velocity:
Using the Airflow Resistance Chart, select a free area velocity that produces an acceptable pressure drop with minimal water penetration.
(Water penetration need not be considered when selecting exhaust iouvers).
Determine Louver Free Area:
Using the free area velocity and total cfm, determine Louver Free Area required. Using Louver Free Area Chart, select a louver with the
required free area. If louver size is given, determine free area from chart and work backwards to determine maximum airflow.
