PERFORMANCE DATA — 579F (cont)
FAN PERFORMANCE — 579F180-300 UNITS (cont)
LEGEND
*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 this page 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.
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 this page 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.
GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES
1. Static pressure losses (i.e., EconoMi$er IV) must be added to external static
pressure before entering Fan Performance table.
2. Interpolation is permissible. Do not extrapolate.
3. Fan performance is based on wet coils, clean filters, and casing losses. See
Accessory/FIOP Static Pressure table on page 193.
4. Extensive motor and drive testing on these units ensures that the full horse-
power and watts range of the motor can be utilized with confidence. Using
fan motors up to the watts or bhp rating shown will not result in nuisance
tripping or premature motor failure. Unit warranty will not be affected.
5. Use of a field-supplied motor may affect wire sizing. Contact your Bryant
representative for details.
