Performance shown is for installation Type B: Free inlet, Ducted outlet. Performance ratings do not include the effects of appurtenances in the airstream. The AMCA Certified Ratings
Seal applies to air performance ratings only.
Sound power level ratings are shown in decibels, referred to 10-12 watts calculated per AMCA Standard 301. Values shown are for inlet LwA sound power levels for 100%, 50% and
0% of peak pressure in Installation Type B: Free inlet, Ducted outlet. dBA sound pressure values are weighted with 11.5 dB attenuation for each octave band at 5 feet.
