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, as shown in Table 12. Selection software is available, through your salesperson, to help
you select the best motor/drive combination for your application.
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.
6. For more information on the performance limits of Bryant’s motors, see the application data section of this book.
