PERFORMANCE RATINGS - MODEL HD50NT

AMCA LICENSED PERFORMANCE

Model			Static Pressure (in. wg Ps)							Nominal
No.		0.0		0.1	.125	.250	.375	Volts	Watts	RPM	Duct Size
HD50NT	CFM	61		51	48	31	9	120	30	1070	4” Round
	Sones	1.9		2.2	2.3	3.0	3.3

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.

*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 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.
