Table 10 — Fan Performance, 50TFF008 High-Static Motor — Vertical Discharge Units
LEGEND
*Motor drive range: 860 to 1080 rpm. All other rpms require field-
supplied drive.
NOTES:
1. Boldface indicates field-supplied drive is required.
2. indicates field-supplied motor and drive are required.
3. Values include losses for filters, unit casings, and wet coils.
See Table 7 for accessory/FIOP static pressure information.
4. Maximum continuous bhp is 3.7 and the maximum continuous
watts are 3313. Extensive motor and electrical testing on these
units ensures that the full range of the motor can be utilized
with confidence. Using your fan motors up to the wattage rat-
ings shown will not result in nuisance tripping or premature
motor failure. Unit warranty will not be affected. See Table 8 for
additional information.
5. Use of a field-supplied motor may affect wire sizing. Contact
your Carrier representative for details.
6. Interpolation is permissible. Do not extrapolate.
