ANATOMY OF A LOUVER
A louver is a device comprised of multiple blades that, when
mounted in an opening, permits flow of air but inhibits the
entrance of other elements. Louvers are typically fabricated
from formed steel or extruded aluminum.
HEAD
Top of the louver and
completes the connection
between the jambs
BLADE
Varies in shapes, sizes
and blade angles to
serve different purposes
DRIP
Top of the louver that fills the
gap between head and
top blade. Equipped with a
drainable channel
BLADE ANGLE
JAMB
The lower or flatter the
blade angle, the easier it is
to get air into the building
Structural support for the
blades as well as channels
water for drainable louvers
SILL
Base of the louver
BLADE STYLES
DRAINABLE BLADE
J BLADE
K BLADE
CHEVRON BLADE
INVERTED Y BLADE
A drainable blade is
equipped with a gutter
to channel water
toward the jambs of
the louver and away
from the airflow.
The J Blade has a
smooth flat profile
devoid of a gutter on
the leading edge.
The K blade has an
offset step in its profile
acting as a rain trap.
The K style blade can
be drainable or
non-drainable.
The Chevron blade
combines closed sight
lines and drainability.
With a C shaped hook
at the top, it is the
primary choice to stop
wind-driven rain.
An Inverted Y or V
blade is intended for
sight proof applications.
With the closed
sightlines, sacrifices in
free area performance
and greater pressure
drop are made.
3
NON-DRAINABLE LOUVERS
Available in a wide array of blade shapes and frame depths,
non-drainable louvers offer value and economy for exhaust
applications or intake conditions where protection against water
infiltration is not critical. Optional hidden mullions provide a
continuous blade appearance on multiple section assemblies.
Ideally suited for special shapes and transitional designs.

DRAINABLE LOUVERS
Drainable blade louvers are designed to reduce water penetration
in non-wind-driven rain applications by collecting water in the
blade gutters and channeling it into frame downspouts and away
from airflow paths. Available in a wide array of blade shapes and
frame depths, non-drainable louvers offer value and economy for

Certified Ratings:
Pottorff certifies that models EDD-445, EDD-637, EFD-435, and
EFD-445, shown herein are licensed to bear the AMCA seal.
The ratings shown are based on test 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.
AMCA defines the beginning point of water penetration as the free area velocity at the intersection of a simple linear regression of test data and the line of 0.01 ounces of water per square foot of free area and is measured through a 48" x 48" louver during a 15 minute
period. The AMCA water penetration test provides a method for comparing louver models and designs as to their efficiency in resisting the penetration of rainfall under specific lab conditions. Pottorff recommends that intake louvers are selected with a reasonable
margin of safety below the beginning point of water penetration in order to avoid unwanted penetration during severe storm conditions.

WIND–DRIVEN RAIN LOUVERS
Our wind-driven rain louvers offer exceptional protection under
the most severe conditions and are available in frame depths
from 2" to 7". The closely spaced vertical blade design of the
ECV-545 provides wind-driven rain performance with 100%
effectiveness at wind velocities up to 50 mph and rainfall up to
8 in/hr. When aesthetic requirements demand a more conventional
louver profile, our EFJ-745 is the ideal solution. Its horizontal
blades, vertically bladed rear screen, and 99.3% effectiveness at
3in/hr as per the AMCA 500-L wind-driven rain test, give the best
of both worlds.

LOUVER TESTING LABORATORY
Pottorff's wind-driven rain and water penetration lab features a
48" vane axial tubular fan providing 55,000 CFM. In front of the
outlet is a system of nozzles which are programmed to sequence
the pattern of spray. In front of this is a ventilation chamber with
■■
ductwork running to an exhaust fan featuring an airflow nozzle to
measure ventilation airflow. Our setup will test louvers per AMCA
500 and 511 with eventual approval for the AMCA CRP program.
Wind-Driven Rain Test – Rates the ability of a louver to
protect openings behind it from water directed at the louver
of speeds up to 50 mph. Published ratings are a statement
of the louver's ability to reject simulated rain including wind
velocity, effectiveness, penetration class and discharge loss
coefficient class.
■■
Water Penetration Test – The Water Penetration test rates
the ability of a louver to protect openings behind it from water
that cascades down a wall or falls vertically in front of it.
This determines the point of water penetration which AMCA
defines as at least 0.01 ounces of water during a 15 minute
test. The sample tested is also tested for air performance.
■■
Air Performance – Published ratings include a graph
for the pressure loss to the louver's free area, the mode
tested (intake or exhaust) and a table of the free area
based on its size.
AIRFLOW REGULATION

that regulate airflow
MANIFOLD

HUMAN MACHINE INTERFACE
All of our testing in our Pottorff Wind-Driven Rain and Water
Penetration Laboratory is able to be automated. For this purpose
we use a new HMI (Human Machine Interface) which is designed
to run any test and continually store the data in our database.
THE HMI SOFTWARE ALLOWS US TO:

Certified Ratings:
Pottorff certifies that models EAA-845, SAJ-835, and SAJ-1235,
shown herein are licensed to bear the AMCA seal. The ratings shown
are based on test 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.
AMCA defines the beginning point of water penetration as the free area velocity at the intersection of a simple linear regression of test data and the line of 0.01 ounces of water per square foot of free area and is measured through a 48”x 48” louver during a 15 minute
period. The AMCA water penetration test provides a method for comparing louver models and designs as to their efficiency in resisting the penetration of rainfall under specific lab conditions. Pottorff recommends that intake louvers are selected with a reasonable
margin of safety below the beginning point of water penetration in order to avoid unwanted penetration during severe storm conditions.
