Table 18 — Fan Performance — 580F240360 (High Heat Units)*

LEGEND

*Standard low-medium static drive range is 1002 to 1151 rpm. Alternate

high-static drive range is 1193 to 1369. Other rpms require a field-
supplied drive.

Refer to page 32 for general Fan Performance Data notes.

NOTE: 

Maximum continuous bhp for the standard motor is 8.7 (for 208/

230-v units) and 9.5 (for 460-v units). The maximum continuous watts is
7915 (for 208/230-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 24 for more information.
