Notes
:
•
Performance tested in accordance with the (ANSI/AMCA 210-07), (ANSI/ASHRAE 51-07) test standards for Certified Aerodynamic
Performance Rating.
•
Sound levels were measured with unit installed in a gasketed ceiling, in a standard room. Sound levels in dB were measured at a distance
of 12 inches from the filter face, with the unit set to produce 90 fpm average face velocity. (Note that data is for a clean filter only. If fan
speed is increased to compensate for filter loading the noise level will increase.)
•
The unit set to produce 90 fpm average face velocity.
•
All data is based on a unit with a 1” pre-filter and clean filter. Results will vary depending on filter media and ducting used.
•
90 fpm values are based on active filter face area.
•
Heat Gain: BTU = Watts x 3.413
