Instructions are available at Performance Data ES-10 Leakage Leakage testing was conducted in accordance with AMCA Standard 500-D and is expressed as CFM per sq. ft. of damper face area. All data has been corrected to represent standard air at 0.075 lb/ft3 (1.201 kg/m3). Pressure Drop Performance data results from testing a 36” x 36” damper in accordance with AMCA Standard 500-D using Figure 5.7B (no duct either side).
