Design incorporates drain gutters in the head member and horizontal blades to channel water to the louver side frames or jambs where water is further channeled through vertical downspouts and out at the sloped louver sill. It has 35 o blades and offers the most free area in the ESD line. The ESD-435 is an extremely efficient louver with AMCA Licensed Performance Data enabling designers to select and apply with confidence.

The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 511 and comply with the requirements of the AMCA Certified Ratings Program. The AMCA Certified Ratings Seal applies to air performance and water penetration ratings. Airflow Resistance (Standard Air- 0.075 Ib/ft^3 ) in. wg Model ESD-435 resistance to airflow varies depending on louver application (air intake or air exhaust). Free area velocities (shown) are higher than the average velocity through the overall louver size. FREE AREA VELOCITY (FL/rain) Water Penetration (Standard Air- 0.075 Ib/ft^3) Test Size 48 in X 48 in - 15 min. test period. OZ./SQ.FT. FREE AREA VELOCITY (Ft/min) The AMCA Water Penetration Test provides a method for comparing vadous 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 fl oz of water (penetration) per ft^2 of louver free area. *The beginning point of water penetration for model ESD-435 is 1,151.00 flJmin 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. [ Greenheck 02/04/05 JOB: DEFOREST WW LIFT STATION Louver MARK: LOUVER SELECTION AND APPLICATION ESD-435 Application of any Louver involves selectin9 an airflow velocity through the louver free area (free area velocity in ) that produces an acceptable pressure drop and for intake applications minimizes carry through of normally encountered rain water. No louver manufacturer warrants their louver to prevent water penetration under all possible combinations of wind and rain. Water penetration through Model ESD-435 begins at 1,151.00 ft/min free area velocity. Intake air louver selection using free area velocity below 1,151.00 fi/rain is recommended. Louver selection invloves the following two steps, and depending on given conditions, either step may come first. Select Free Area Velocity: Using the Airflow Resistance Chart, select a free area velocity that produces an acceptable pressure drop with minimal water penetration. (Water penetration need not be considered when selecting exhaust iouvers). Determine Louver Free Area: Using the free area velocity and total cfm, determine Louver Free Area required. Using Louver Free Area Chart, select a louver with the required free area. If louver size is given, determine free area from chart and work backwards to determine maximum airflow.
