NuTone 605RP Certified Test Data, Air delivery of a ventilating system may be determined by

CERTIFIED TEST DATA

Air delivery and sound level ratings are certified by the Home Ventilating Institute Division of AMCA, based on testing performed by an independent third party testing laboratory, in accordance with HVI standards. This NuTone model is listed by Underwriters' Laboratories Inc.

The air delivery of a ventilating system may be determined by:

1.Determine the equivalent duct length for each 90 degree elbow by adding one foot of duct length for each inch of duct diameter, i.e., a 4 inch diameter duct elbow equals 4 feet equivalent duct length and an 8 inch diameter duct elbow equals 8 feet equivalent duct length.

2.Add the total straight length of duct and the equivalent length for each elbow to obtain the total equivalent duct length.

3.Locate the intersection of the fan performance curve and the total equivalent duct length curves and draw a vertical line down to the CFM scale and read the system air performance.

(NOTE: 31⁄4" x 10" duct equals 6 inch diameter duct.)
