ANATOMY OF A LOUVERA 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.

K BLADEJ BLADE INVERTED Y BLADECHEVRON BLADE

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.

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.

An Inverted Y or V blade is intended for sight proof applications. With the closed sight-lines, sacrifices in free area performance and greater pressure drop are made.

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.

NON-DRAINABLE LOUVERSAvailable 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.

Certified Ratings:Pottorff certifies that model EFJ-437-HP, shown herein is 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.

DRAINABLE LOUVERSDrainable blade louvers are designed to prevent water penetration in non-wind-driven rain applications by collecting water in frame and blade gutters and channeling it into downspouts and away from airflow. These models are available in a wide array of anodized and painted finishes including custom color matching.

Certified Ratings:Pottorff certifies that models EDD-445, EDD-637, EFD-435, EFD-445, and EFD-645, 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 LOUVERSOur 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 99.6% 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, offer the best of both worlds.

Certified Ratings:Pottorff certifies that models ECD-245, ECD-445, ECD-635, ECD-745, ECV-245, ECV-445, ECV-545, EFJ-937 and 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.

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. AMCA Wind-driven Rain Ratings based upon a test louver size having 39-3/8" X 39-3/8" core area.

*Applies when the CD-55 damper option is utilized and the damper is in the closed position.

VENTILATION FAN Has the ability to produce up to 24,000 cfm of airflow for use in water penetration and air performance tests

LOUVER TESTING LABORATORYPottorff'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.

MANIFOLD Allows water to fall in front or down the wall of the louver to simulate conditions in the Water Penetration Test

WET WALL MANIFOLD Allows water to fall down the wall to the face of the louver at a prescribed 4 in. per hour

FAN AND NOZZLES Five nozzles along with the fan, simulate rain, to suit the spread of rain required

AIRFLOW REGULATION A series of chambers that regulate airflow

WATER PRESSURE NOZZLESReleases water to simulate WDR rain rates which are tested at 3 and 8 in. rainfall/hr.

LOUVER Louvers are fabricated to a uniform 48" × 48" and placed in an appropriate opening in the drainage chamber wall where tests are performed

DRAINAGE CHAMBERWater collected to provide readings for water penetration test

HUMAN MACHINE INTERFACEAll 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.

■■ Plot the desired points for testing

■■ Start and stop tests automatically

■■ Live view of all data being retrieved at any point during testing. For example: wind speed, differential pressure, etc.

■■ Control any aspect of a test; for example: fan speed, rain nozzle intervals, etc.

■■ Tests automations at our desired data points

XAV-545MEETS ICC-500 2014

The XAV-545 and XSV-845 were designed to FEMA 320 or FEMA 361 guidelines for shelters or safe rooms. They have been designed to withstand design loads of ± 300 PSF produced by extreme wind phenomena such as tornadoes and hurricanes. They have been tested with impacts of 15lb 2" x 4"s traveling at 100 MPH per ICC 500. This makes both the XAV-545 and XSV-845 compliant for wind borne debris in all tornado or hurricane regions in the United States.
