APPENDIX C — 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 recommen-
dations. In cases when two motor/drive combinations
would work, Carrier recommended the lower horsepower
option.
5. For information on the electrical properties of Carrier’s
motors, please see the Electrical information section of
this book.
Boldface
indicates field-supplied drive is required.
NOTES:
1. For more information, see General Fan Performance Notes above.
2. Recommend using field-supplied fan pulley (part number
KR11AG006) and belt (part number KR30AE039) with field-sup-
plied drive.
3. Recommend using field-supplied motor pulley (part number
KR11HY161) and belt (part number KR30AE035) with field-sup-
plied drive.
