CFM values shown
in black are the most
efficient selections.
Values shown in gray
are not recommended.
Performance certified is for Model SBC for installation type A: free inlet, free outlet. Power rating (Bhp) does not include transmission losses. Performance ratings do not include
the effects of appurtenances (accessories). The sound ratings shown are loudness values in fan sones at 5 ft (1.5 m) in a hemispherical free field calculated per AMCA Standard 301.
Values are for installation type A: free inlet hemispherical sone levels.*Sones shown apply to the highest cataloged CFM in black type at each fan RPM. For selections at other CFM and static
pressure points,refer to CAPS, the Computer Aided Product Selection Program.
