The performances shown are with inlet grille, backdraft damper and outlet duct. RPM shown is nominal and the performance is based on actual speed of test.
The sound ratings shown are loudness values in fan sones at 5' (1.5m) in a hemispherical free field calculated per AMCA Std. 301. Values shown are for
installation Type B: free inlet fan sone levels.

** There is difference between sone values certified by HVI for
residential use and by AMCA for commercial/industrial use. Exact
comparison of these values is not possible. This difference is
mainly due to procedures used to convert measured sound to
perceived sound. ANSI S3.4, used by both HVI and AMCA,
specifies a procedure for calculating loudness as perceived by a
typical listener under specific conditions. HVI establishes values
at a distance of 5 feet from the fan in a "spherical free field"; AMCA
establishes values at a distance of 5 feet in a "hemispherical free
field". HVI and AMCA have different rules for rounding sone
values.

new testing technologies and procedures
prescribed by the Home Ventilating Institute,
for off-the-shelf products, as they are available
to consumers. Product performance is rated
at 0.1 in. static pressure, based on tests
conducted in AMCA’s state-of-the-art test
laboratory. Sones are a measure of humanlyperceived loudness, based on laboratory
measurements.
