HomeMy WebLinkAboutPRODUCT APPROVAL DRAINABLE BLADE LOUVERApplication and Design ESD-435X is a Florida Product Approved stationary drainable blade extruded aluminum louver designed to protect air intake and exhaust openings in building exterior walls. ESD-435X is tested in accordance with AMCA 500-L Air Performance and Water Penetration. ESD-435X is tested in accordance with AMCA 540 Test Method for Louvers Impacted by Wind Borne Debris (Basic Protection, Missile Level D). ESD-435X is licensed to bear the AMCA seal allowing design professionals to select and apply with confidence. ESD-435X is tested and qualified per the following Florida test protocols: TAS 201 (Large Missile Impact), TAS 202 (Uniform Static Air Pressure) and TAS 203 (Cyclic Wind Loading). ESD-435X is approved by Florida for use in Florida’s High Velocity Hurricane Zone. ESD-435X is qualified for wind loads up to 200 PSF (size and configuration dependent, refer to the UL published certification for size and design load rating restrictions).

ESD-435XPERFORMANCE DATA Free Area Chart (Sq. ft.) Airflow Resistance (Standard Air - �075 lb/ft3)Water Penetration (Standard Air - �075 lb/ft3) Model ESD-435X 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) 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 .01 oz. of water (penetration) per sq. ft. of louver free area. *The beginning point of water penetration for Model ESD-435X is 989 fpm free area velocity� These perfor mance ratings do not guarantee a louver to be weather proof or stormproof and should be used in combination with other factors including good engineering judgement in selecting louvers.

Pressure Drop Data VCD-23 This pressure drop testing was conducted in accordance with AMCA Standard 500-D using the three configurations shown. All data has been corrected to represent standard air at a density of .075 lb/ft3 (1.2 kg/m3). Actual pressure drop found in any HVAC system is a combination of many factors. This pressure drop information along with an analysis of other system influences should be used to estimate actual pressure losses for a damper installed in a given HVAC system. AMCA Test Figures Figure 5.2 Illustrates a ducted damper exhausting air into an open area. This configuration has a lower pressure drop than Figure 5.5 because entrance losses are minimized by a straight duct run upstream of the damper. Figure 5.3 Illustrates a fully ducted damper. This configuration has the lowest pressure drop of the three test configurations because entrance and exit losses are minimized by straight duct runs upstream and downstream of the damper. Figure 5.5 Illustrates a plenum mounted damper. This configuration has the highest pressure drop because of extremely high entrance and exit losses due to the sudden changes of area in the system. 5D 6D 5D D 4 (W) (H) 3.14 5D 6D 5D D 4 (W) (H) 3.14 5D 6D 5D D 4 (W) (H) 3.14 5D 6D 5D D 4 (W) (H) 3.14 5D 6D 5D D 4 (W) (H) 3.14 AMCA Certified Pressure Drop Data VCD-23 Velocity (fpm)Pressure Drop (in. wg)Velocity (fpm) Pressure Drop (in. wg)Velocity (fpm) Pressure Drop (in. wg) 500 0.01 500 0.01 500 0.01 1000 0.05 1000 0.03 1000 0.02 1500 0.11 1500 0.06 1500 0.05 2000 0.19 2000 0.10 2000 0.09 2500 0.29 2500 0.16 2500 0.14 3000 0.41 3000 0.23 3000 0.19 3500 0.55 3500 0.30 3500 0.27 4000 0.72 4000 0.40 4000 0.35 12 in. x 12 in.

Tested for leakage in accordance with ANSI/AMCA Standard 500-D, Figure 5.5. Tested for air performance in accordance with ANSI/AMCA Standard 500-D, Figures 5.2, 5.3 and 5.5. Torque Data are based on a torque of 5.0 in.lb./ft² (0.56 N·m) applied to close and seat the damper during the test.

(457mm) high, actuators may also require clearances above and/or below the damper frame. “B” and “T” dimensions are worst case clearance requirements for some dampers less than 18 in. (457mm) high. All damper sizes under 18 in. (457mm) high do not require these worst case clearances. If space availability above or below the damper is limited, each damper size should be individually evaluated.

Multiple section dampers can be jackshafted together so that all sections operate together as shown below. NOTE: Dampers larger than 48 in. x 74 in. (1219mm x 1880mm) are not intended to be structurally self supporting. Additional horizontal bracing is recommended to support the weight of the damper and vertical bracing should be installed as required to hold against system pressure. Specifications Control dampers meeting the following specifications shall be furnished and installed where shown on plans and/or as described in schedules. Damper blades shall be 16 ga. (1.5mm) galvanized steel 3V type with three longitudinal grooves for reinforcement. Blades shall be completely symmetrical relative to their axle pivot point, presenting identical resistance to airflow and operation in either direction through the damper (blades that are non-symmetrical relative to their axle pivot point or utilize blade stops larger than 1⁄2 in. [13mm] are unacceptable). Blade seals shall be TPE. Linkage shall be blade-to- blade concealed in jamb (out of the airstream) to protect linkage and reduce pressure drop and noise. Damper frame shall be 16 ga. (1.5mm) galvanized steel formed into a structural hat channel shape with reinforced corners to meet 11 ga. (3.1mm) criteria. Bearings shall be corrosion resistant, permanently lubricated, synthetic (acetal) sleeve type rotating in extruded holes in the damper frame for maximum service. Axles shall be square and positively locked into the damper blade. Jamb seals shall be flexible stainless steel compression type to prevent leakage between blade end and damper frame. The damper manufacturer’s submittal data shall certify all air leakage and air performance pressure drop data is licensed in accordance with the AMCA Certified Ratings Program for Test Figures 5.2, 5.3 and 5.5. Damper air performance data shall be developed in accordance with the latest edition of AMCA Standard 500-D. Basis of design is model VCD-23.
