Pressure Drop
36 in. x 36 in. (914mm x 914mm) Damper
Performance data results from testing a 36 in. x 36 in. (914mm x 914mm) damper in accordance with AMCA Standard 500-D
using Figure 5.3 for the WD-400 and Figure 5.7A for the WD-410. All data has been corrected to represent standard air at 0.075
lb/ft
3
(1.201 kg/m

).
Leakage
36 in. x 36 in. (914mm x 914mm) Damper
Leakage testing was conducted in accordance with AMCA
Standard 500-D and is expressed as cfm/ft

of damper face
area. All data has been corrected to represent standard air at
0.075 lb/ft
