APPENDIX III. FAN PERFORMANCE

General Fan Performance Notes:

1. Interpolation is permissible. Do not extrapolate.
2. External static pressure is the static pressure difference between the return duct and the supply duct plus the static

pressure caused by any FIOPs or accessories.

3. Tabular data accounts for pressure loss due to clean filters, unit casing, and wet coils. Factory options and accessories

may add static pressure losses.

4. The Fan Performance tables offer motor/drive recommendations. In cases when two motor/drive combinations would

work, Bryant recommended the lower horsepower option.

5. For information on the electrical properties of Bryant’s motors, please see the Electrical information section of this

book.
