2 Applications LC-50 adjustable louvers are integral louvers and dampers. They are designed for very tight closure against wind and weather. Drainable heads channel water to the side frames, which channel through vertical downspouts and out the bottom of the louver at the sill. These models are efficient at minimizing water penetration. LM-50 adjustable louvers are designed for tight closure. Drainable heads channel water to the side frames, which channel through vertical downspouts and out the bottom of the louver at the sill. These models are efficient at minimizing water penetration. LV-50 and LV-51 stationary louvers are designed to meet heavy duty application and environmental requirements. Drainable heads channel water to the side frames, which channel through vertical downspouts and out the bottom of the louver at the sill. These models are efficient at minimizing water penetration with low resistance to airflow. LV-1800 stationary louvers are designed to protect air intake and exhaust openings in exterior walls of buildings. Drainable heads channel water to the side frames, which channel through vertical downspouts and out the bottom of the louver at the sill. These models are efficient at minimizing water penetration.

Testing to AMCA 500 is performed under a certain set of laboratory conditions. This does not guarantee that other conditions do not occur in the actual environment where louvers must operate. The louver system should be designed with a reasonable safety factor for louver performance. To ensure protection from water carryover, design with a performance level somewhat below maximum desired pressure drop and 0.01 ounce/square foot of water penetration. 64 square ft (6 square meters), not to exceed 0 x 90 in. (3,048 x 2,286 mm) 5 pounds/square foot (2.4 kg/ square meter) Free Area Total area is the area within the dimensions of the louver. Obstructed area is the area that does not allow airflow because of the construction of the louver. Free area is the area which allows airflow. Use these tables to find the free area for the louvers.

12 Pressure Drop To determine the pressure drop for your damper: 1. Determine the height and width of your damper. 2. Use Table 5 through Table 11 to find the free area (sq. ft.) of your louver. 3. Calculate the damper s flow in cubic feet per minute (cfm) using the formula Flow (cfm) = Free Area (sq. ft) x Velocity (fpm) 4. To find the static pressure drop (inches w.g.) for your damper, solve this equation: Static Pressure Drop = 1.60 x {[(CFM / Free Area) - Velocity] / 4005} 2 5. To find the overall pressure drop for your louver, use the equation: Overall Pressure Drop = Static Pressure Drop x 2.8 You can also use Figure 8 and Figure 9 to estimate the overall pressure drop for your louver (248.95).90 (224.05).80 (199.15).70 (174.25).60 (149.35).50 (4.45).40 (99.56) Static Pressure Drop in w.g.

KYNAR is a type of Polyvinylidene Difluoride (PVDF), which is a highly non-reactive and pure thermoplastic fluoropolymer used in applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat and low smoke generation during a fire event. A fine powder grade PVDF is used as the principal ingredient of high-end paints for metals, which have extremely good gloss and color retention. These paints are in use on many prominent buildings around the world, as well as on commercial and residential metal roofing. Building Efficiency 507 E.
