The performance ratings include the effects of inlet grille and backdraft damper in the airstream. Speed (RPM) shown is nominal. Performance is based on actual speed
of test. The sound ratings are loudness values in fan sones at 5’ (1.5m) in a hemispherical free eld calculated per AMCA Std. 301. Values shown are for Installation Type
B: Free inlet fan sone levels. Air performance shown is for Installation Type B: Free inlet, Ducted outlet.

*There is a difference between sone values certied 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 the procedures used
to convert measured sound to perceived sound. ANSI S3.4, used by both HVI
and AMCA, species a procedure for calculating loudness as perceived by a
typical listener under specic conditions. HVI establishes values at a distance
of 5 feet from the fan in a “spherical free eld’’; AMCA establishes values at
a distance of 5 feet in a “hemispherical free eld”. HVI results are rounded to
the nearest 0.5 sone, AMCA to the nearest 0.1 sone.

HVI-2100 CERTIFIED RATINGS comply with 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
humanly-perceived loudness, based on laboratory
measurements.
