Bhp — Brake Horsepower Input to Fan
FIOP — Factory-Installed Option
Watts — Input Watts to Motor
NOTES:
1. Boldface indicates field-supplied drive required.
2. indicates field-supplied motor and drive required.
3.
indicates maximum bhp/watts of standard motor and drive.
4. Factory-shipped motor drive range is 862 to 1132 rpm. Other rpms
may require a field-supplied drive.
5. Maximum continuous bhp is 4.25 and maximum continuous watts
are 3775. Do not adjust motor rpm such that motor maximum bhp
and/or watts is exceeded at the maximum operating cfm.
6. Static pressure losses (i.e., economizer) must be added to external
static pressure before entering Air Delivery table.
7. Interpolation is permissible. Do not extrapolate.
8. Fan performance is based on wet coils, clean filters, and casing losses.
See Table 7 for accessory/FIOP static pressure information.
9. Extensive motor and drive testing on these units ensures that the full
horsepower and watts range of the motor can be utilized with confi-
dence. Using your 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.
