Sound Power Ratings for Supply Air Blowers in our Millen-
nium Units with High Gas Heat, Economizer, 2: T/A Filters
and Wet DX Sound power calculations complements of Lau’s
revised “Whirlwind” application selection software for air mov-
ing components.
The sound ratings above occur at the blower wheel. To deter-
mine the sound rating at a unit’s supply and return air duct
connection, subtract the attenuation factors listed below.
NOTE: These values have been accessed using a model of
sound propagation from a point source into the
hemispheric free field (AMCA 303-79). The dBA val-
ues provided are to be used for reference only. Cal-
culation of dBA values cover matters of system
design, and the fan manufacturer has no way of
knowing the details of each system. This constitutes
an exception to any specification or guarantee
requiring a dBA value or sound data in any other
form than sound power level ratings.
