Performance certified is for installation type B: Free inlet, Ducted outlet. Power rating (Bhp) does not include transmission losses. Performance ratings do not include the effects of appurtenances (accessories).

The sound power level ratings shown are in decibels, referred to 10-12watts, calculated per AMCA Standard 301. Values shown are for inlet LWi , LWi A and outlet LWo , LWo A sound power levels for installation type B: Free inlet, Ducted outlet. Ratings for inlet sound do not include the effects of duct end correction. Ratings for outlet sound include the effects of duct end correction. The A-weighted sound power ratings shown have been calculated per AMCA Standard 301. The AMCA Certified Ratings Seal applies to LWi A and LWo A values only.
