*There is a 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 the 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.

SONES

Static Pressure (in. wg Ps)

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 field 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.

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.
