Performance is for exhaust fans installation type A: Free inlet, Free outlet. Supply fans performance is approximately 20% less for each horsepower (HP). 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. Values are for installation type A: Free inlet sone levels.
