CALCULATING PRESSURE LOSSBased upon a given flow rate (in CFM), the flowing pressure loss maybe determined from the “air performance” graph, knowing the sq. ft. offree area of the louver. Alternately, the free area may be determinedbased upon a volumetric flow rate and a maximum pressure loss.Utilizing the “air performance” graph.

CALCULATING MAXIMUM AIRFLOW BEFORE WATER PENETRATION

The “free area flow rate” at which water penetration commences (.01 oz. ofwater) is established at, 879 fpm (268), and will vary depending upon actualweather conditions. The “water penetration” graph illustrates the results ofactual laboratory test on a 48” x 48” (1219 x 1219) test sample subjected tohypothetical rainfall conditions.

SUGGESTED SPECIFICATIONS LOUVER MODEL: LEC-04/ SERIES GENERAL:

Furnish and install at locations where indicated on the drawings or as described in schedules with high performance weather-resistant drainable louver Model LEC-04/series as manufactured by DOWCO Products Group, 1855 South 54th Ave., Cicero, IL. 60804. Tel. 708-652-9100, Fax 708-652-9158 (www.safeair-dowco.com/contact.asp). All louvers shall manufactured under ARRA – American Recovery Reinvestment Act, “Buy American Stimulus Provision” and shall have a factory certified Union Label. Submit complete submittals or shop drawings to the architect/engineer for approval. All opening sizes shall be field verified prior to fabrication. MATERIAL:

Frames and blades thickness shall be .081" (2.96mm) extruded aluminum alloy 6063-T5, T52 or T6. Sill and jamb frames shall be caulked to prevent water penetration to interior wall construction. Blades are attached to jamb frames by means of plated steel screws. All fasteners to be aluminum, plated carbon steel, or stainless steel. Frames shall have integral caulking slot and retaining beads. Stationary louvers shall be furnished with bird and / or insect screens, supports and finishes as specified and as required for a complete installation. PERFORMANCE:

Louvers shall be tested in accordance with AMCA Standard 500-L and licensed under the AMCA Certified Ratings Seal for both air performance and water penetration. The louvers shall have a minimum of 7.92 ft2. (0.736 m2) (50%) free area on a 48 inch x 48 inch (1219 x 1219) louver. The rating shall show a maximum water penetration of .01 oz. at an air flow of 879 FPM (4.47 m/s) free area velocity based on a 15 minute test duration. The Static Pressure Loss shall not be more than 0.18 in. H2O of water gauge (0.04 kPa) at an air flow of 1000 FPM (5.08 m/s) free area velocity. STRUCTURAL DESIGN CRITERIA:

Louvers shall be designed and furnished with all the supports required to withstand a negative and positive wind load of 25 psf (1.20 kPa) @ delta L/180 deflection based on the maximum single section of 120 x 84 (3048 x 2135) or 84 x 120 (2135 x 3048). Larger sizes and higher wind loads require additional structural supports. Due to the variation of job requirements and local building codes, structural supports shall be analyzed on a job to job basis. FINISH:

All louvers shall be finished with DOWCO’s Kynar 500 with 100% resin Fluoropolymer coating. Finish to adhere to a 4H hardness rating. All finishing procedures shall be one continuous operation and the coating shall meet or exceed all requirements of AAMA Specification 2605-05 “Voluntary Specification for High Performance Organic Coatings on Architectural Extrusions and Panels.” Manufacturer shall supply a standard 5-year limited warranty against failure and excessive fading or upon request a 20-year limited warranty against failure and excessive fading.
