About this file
This is a product specification document for the EDD-401 Stationary Louver with Dual Drainable Blade manufactured by Greenheck Fan Corporation.
The EDD-401 is an extruded aluminum louver featuring heavy gauge 6063-T5 aluminum construction with a 4-inch frame and dual drainable blades positioned at 37° and 45° on 4-inch centers. The louver has a 4-inch depth and mechanically fastened construction with a mill finish. Minimum size is 12 inches by 12 inches, and maximum single section size is 120 inches by 120 inches, limited to 70 square feet. The unit can withstand a 25 PSF wind load. Key performance specifications include a free area of 8.22 square feet (51.4% of louver area), a beginning point of water penetration at 992 fpm free area velocity with a maximum intake volume of 8,154 cfm, and a pressure drop of 0.078 inches of water gauge at 6,000 cfm intake. The louver is AMCA certified and tested in accordance with AMCA Publication 511 and AMCA Standard 500-L. Available options and accessories include bird screens, blank-off panels, extended sill, filter racks, flange frames, glazing frames, hinged frames, insect screens, mounting angles, security bars, architectural finishes, and welded construction alternatives. The document includes detailed free area charts for various louver dimensions and performance graphs showing airflow resistance and water penetration characteristics.

Model EDD-401 resistance to airflow (pressure drop) varies depending on louver application (air intake or air exhaust). Free area velocities (shown) are higher than average velocity through the overall louver size.
See louver selection information. (Test Figure 5.5-6.5)
The AMCA Water Penetration Test provides a method for comparing various louver models and designs as to their efficiency in resisting the penetration of rainfall under specific laboratory test conditions. The beginning point of water penetration is defined as that velocity where the water penetration curve projects through 0.01 oz. (3 g) of water (penetration) per sq. ft. (m²) of louver free area. *The beginning point of water penetration for Model EDD-401 is 992 fpm (5.039 m/s) free area velocity. These performance ratings do not guarantee a louver to be weatherproof or stormproof and should be used in combination with other factors including good engineering judgement in selecting louvers.
