  LEGEND
*Standard low-medium static drive range is 1066 to 1283 rpm. Alternate high-
static drive range is 1332 to 1550. Other rpms require a field-supplied drive.
Refer to page 194 for general Fan Performance Data notes.
NOTE: Maximum continuous bhp is 10.20 (208/230 and 575 v) or 11.80 (460 v)
and the maximum continuous watts are 9510 (208/230 and 575 v) or 11,000
(460 v). Do not adjust motor rpm such that motor maximum bhp and/or watts is
exceeded at the maximum operating cfm.
