PERFORMANCE DATA — 579F (cont)
FAN PERFORMANCE — 579F180-300 UNITS
LEGEND
*Standard low-medium static drive range is 891 to 1179 rpm (208/230 v and
460 v) or 1159 to 1429 (575 v). Alternate high-static drive range is 1227 to 1550
(208/230 v and 460 v only). Other rpms require a field-supplied drive.
Refer to page 194 for general Fan Performance Data notes.
NOTE: Maximum continuous bhp is 4.25 (208/230 v and 460 v) or 3.45 (575 v)
and the maximum continuous watts are 3775 (208/230 v and 460 v) or 3065
(575 v). Do not adjust motor rpm such that motor maximum bhp and/or watts is
exceeded at the maximum operating cfm.

*Standard low-medium static drive range for the 216 size is 910 to 1095 rpm.
Standard low-medium static drive range for the 240 size is 1002 to 1225 rpm.
Alternate high-static drive range for the 216 size is 1069 to 1287. Alternate high-
static drive range for the 240 size is 1193 to 1458 rpm. Other rpms require a field-
supplied drive.
Refer to page 194 for general Fan Performance Data notes.
NOTE: Maximum continuous bhp for the 216 size is 5.90. Maximum continuous
bhp for the 240 size is 8.70 (208/230 and 575 v) or 9.50 (460 v). The maximum
continuous watts for the 216 size is 5180. The maximum continuous watts for the
240 size is 7915 (208/230 and 575 v) or 8640 (460 v). Do not adjust motor rpm
such that motor maximum bhp and/or watts is exceeded at the maximum operat-
ing cfm.
