PERFORMANCE DATA SEBR-10 SERIES

Performance data results from testing a 12 in. x 12 in. and 36 in. x 36 in. damper in accordance with AMCA Standard 500D using Figure 5.3 (fully ducted), 5.2 (ducted exhausting into an open area), and 5.5 (plenum mounted) . All data has been corrected to represent standard air density at 0.075 lb/ft3 (1.201 kg/m3).
