Performance certified is 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 shown are for installation type A: Free inlet hemispherical sone levels. The AMCA Certified Ratings Seal applies to sone ratings only.
