Performance shown is for installation type B: free inlet, ducted outlet. Power rating (Bhp) does not include drive losses. Performance ratings do not include the effects of appurtenances
in the airstream.
The sound power level ratings shown are in decibels, referred to 10
-12
watts calculated per AMCA Standard 301. Values shown are for inlet LwiA sound power levels for installation type
B: free inlet, ducted outlet. Ratings do not include the effects of end correction.
* Sound power values listed are at 0.50 inches pressure wg for each rpm.
** dBA sound pressure values are weighted with 11.5 dB attenuation for each octave band at 5 feet. Listed sound pressure value is for each rpm at 0.50 inches wg.
