Table 18 — Fan Performance — 48TMD025 (Low Heat Units)*
LEGEND
*Standard low-medium static drive range is 1002 to 1151 rpm. Alter-
nate high-static drive range is 1193 to 1369. Other rpms require a
field-supplied drive.
Refer to page 39 for general Fan Performance Data notes.
NOTE: Maximum continuous bhp for the standard motor is 8.7 (for
208/230 and 575-v units) and 9.5 (for 460-v units). The maximum
continuous watts is 7915 (for 208/230 and 575-v units) and 8640 (for
460-v units). Do not adjust motor rpm such that motor maximum bhp
and/or watts is exceeded at the maximum operating cfm. See
Table 25 for additional information.
