ANATOMY OF A LOUVER A louver is an air termination or entry device composed of multiple blades which, when mounted in an opening, permits airflow but inhibits the ingress of other elements. The type of louver that is selected is dependent on the application, geographic location, and local building codes.
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
The lower or flatter the blade angle, the easier it is to get air into the building.
JAMB
Structural support for the blades as well as channels water for drainable louvers.
SILL
Base of the louver.
BLADE STYLES
DRAINABLE BLADE A drainable blade is equipped with a gutter to channel water toward the jambs of the louver and away from the airflow.
J-BLADE
K-BLADE
CHEVRON BLADE 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.
INVERTED Y BLADE 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 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.
3
NON-DRAINABLE LOUVERS
Non-drainable louvers offer value and economy for exhaust applications or intake conditions where protection against water filtration is not critical. Optional hidden mullions provide a continuous blade appearance.

SEvere DUTY Louvers WIND-DRIVEN RAIN
One of the benefits of wind-driven rain louvers is that they are sight proof. The tight blade spacing and steep blade angles of these louvers force water to collect on the blade surface where it is channeled into vertical downspouts.

LOUVER TESTING LABORATORY Pottorff’s State of the Art Wind-Driven Rain and Water Penetration test rig, constructed in accordance with AMCA Standard 500-L, allows us to accurately measure louver water infiltration. Our chamber is designed to feature storm conditions (wind-blown rain), still air (no wind) conditions, as well as Air Performance; better known as “Pressure Drop” or “Pressure Loss”.
WETTED WALL MANIFOLD Manifold used to simulate water runoff on the side of a building during Water Penetration Testing.
■ WIND-DRIVEN RAIN TEST (WDR) – Rates a louver’s ability to mitigate water entrainment under storm conditions, while also simulating various active HVAC system ventilation rates through the test sample. Louvers are generally subjected to two wind speeds, 29 and 50mph, which are directed at the face of the sample. The test features a wind-driven rainfall rate of up to 8" per hour. ■ WATER PENETRATION TEST (WP) – Often called “Still Air Water Penetration” determines what is known throughout the industry as “the beginning point of water penetration” and simulates both a moderate, vertical rainfall as well as building runoff. The Beginning Point of Water Penetration is defined by AMCA as .01 ounces of water per square foot of louver Free Area during a 15-minute test. ■ AIR PERFORMANCE (AP) – Pottorff’s Test Chamber has the ability to accurately measure louver Pressure Drop at various airflow rates which is known as Air Performance Testing. The resulting ratings in simple terms are used to compare the difficulty airflow (rated in pressure differential) will encounter when passing through a louver with a given Free Area and blade design. Louvers are generally tested in both intake and exhaust configurations.
VENTILATION FAN With capacity up to 24,000 cfm, our ventilation fan is able to recreate most real world HVAC system airflows during product testing.
AIRFLOW MEASUREMENT Using calibrated nozzles with known diameters and a differential pressure, we can accurately measure airflow during testing.
COLLECTION CHAMBER The collection chamber allows us to collect and measure water that might penetrate louvers during both Wind-Driven Rain and Water Penetration Testing.
WDR SPRAY NOZZLES Specialty nozzles, calibrated and used to generate a uniform spray pattern during WDR for rainfall rates for both 3" per hour and 8" per hour.
RAINFALL MANIFOLD Water basin and nozzles used to simulate 4" per hour vertical rain during the Water Penetration Test.

THE HMI SOFTWARE ALLOWS US TO:
■ 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
LOUVER Sample under test. Industry standard product size for WP is 48"× 48" O.D. with varying Core Area, where as all WDR samples are 48" O.D. with a 1-Meter × 1-Meter Core Area as the Core Area is taken into account when calibrating the WDR Chamber prior to test.
WIND GENERATOR Tube Axial Fan capable of generating sustained wind speeds in excess of 50 mph.
