3 Miami-Dade The EFD--MD and ECD--MD are engineered and tested to withstand extreme loads, debris impact, and cyclic fatigue failure associated with the severe weather effects of hurricanes (ECD--MD has Miami-Dade approval # and the EFD--MD has Miami-Dade approval # ). Constructed from 0-T extruded aluminum, both louver models offer a unique load-bearing design that accommodates installations of unlimited width without adding costly intermediate structural supports required by other products. The EFD- -MD has a single section assembly up to " wide by 1 high and the ECD--MD, specially designed for its winddriven rain and sight proof protection, has a single section assembly up to 0-1/ wide by 2-1/ high. Specially designed water-resistant seam covers further enhance performance and aesthetics of these industry leading products. Pottorff architectural products are designed for use in most geographical areas within the United States. Pottorff can also design modify or reinforce standard products for special requirements, such as high wind, heavy snow, industrial environments, special mounting conditions, etc. Consult your local representative for more information.

4 Wind-Driven Rain Backed by AMCA certification our wind-driven rain louvers offer exceptional protection under the most severe conditions and are available in frame depths from to ". The closely spaced vertical blade design of the ECV- provides our most effective wind-driven rain performance with 0% effectiveness at wind velocities up to 0 mph and rainfall up to in/hr. When aesthetic requirements demand a more conventional horizontal blade profile our EF- is the ideal solution with " on center traditional -blade fascia and 0% in/hr rain fall. Pottorff architectural products are designed for use in most geographical areas within the United States. Pottorff can also design modify or reinforce standard products for special requirements, such as high wind, heavy snow, industrial environments, special mounting conditions, etc. Consult your local representative for more information.

6 Non- 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. head louvers blend the aesthetic appeal of a non-drainable blade with the high performance water penetration protection of a drainable blade louver by incorporating a drainable head member to capture water that cascades down the face of the building, channeling it into downspouts and away from the airflow paths.

8 Combination/Operable EXD Combination louvers feature stationary front blades and operable rear blades to ensure proper weather protection when open as well as a consistent appearance in both the open and closed positions. Optional low leakage seals provide further environmental protection in the closed position. Operable blade louvers provide weather protection when open and positive shutoff when no airflow is required. These units incorporate center pivoted blades that can be controlled manually with a pull chain, hand quadrant or hand crank; or automatically with electric or pneumatic actuators. EBE- and EBI- incorporate backdraft damper blades for automatic shutoff when there is no airflow and can be used for either exhaust and intake applications.

12 Finishes CLEAR ANODIZE Clear oxide coating for aluminum. Clear anodize pre-oxidizes aluminum extrusion surface for uniform clear finish not easily affected by natural oxidizing influences. Improved metallic luster appearance is similar to clean mill finish extrusions. 21-R1 (Aluminum Association Code AA-C22A1) provides 0. mils (0.01) minimum surface depth treatment recommended for severely corrosive or abrasive atmosphere exposure. Clear lacquer over clear anodize available on request. HIGH PERFORMANCE FLUOROPOLYMER Maintenance free high performance fluoropolymer coating complies with AAMA 20 and provides truly excellent color retention, adhesion properties and weather resistance to chalking and fading. Standard year warranty with optional 20 year warranty is available. BAED ENAMEL Baked enamel combines color permanence, low maintenance and economy. The baked enamel provides a semigloss finish with improved economy. COLOR ANODIZE Electrolytically deposited coating on aluminum. The color anodize process specified in Aluminum Association Code AA- C22A electrolytically deposits inorganic color pigment finish to a 0. mils (0.01) minimum surface depth on sulfuric acid anodized aluminum extrusions. Treated aluminum is sealed to convert freshly formed aluminum oxide finish to a corrosion resistant, inert condition. Available only on aluminum; some slight shade variation may occur. Anodized chips PRIME COAT Primer preparation for field painting. Pottorff offers alkyd prime coat finish applied to chemically cleaned aluminum or steel louvers. Finish may be field top-coated with epoxy, vinyl, urethane, and other heavy-duty coatings within six months of application. Prime coat contamination occurs before field painting and requires a field cleaning prior to painting. Finishes enhance louver appearance by matching or contrasting with adjacent surfaces and extend weather resistance. Color matching is available upon request. 1 Blue Mound Road, Fort Worth, Texas Phone: Fax: info@pottorff.com PLB une 20
