LEGEND
Bhp — Brake Horsepower Input to Fan
ESP — External Static Pressure
Bold indicates field-supplied drive is required.
Plain type indicates standard motor and standard drive.
Underlining indicates a different motor and drive combination other than
the standard motor and standard drive combination is required. Refer to
fan motor and drive tables to complete selection.
* For FHS120, these operating points require different motor and drive
combinations.
NOTES:
1. Maximum allowable fan speed is 1200 rpm for all sizes.
2. Fan performance is based on deductions for wet coil, clean 2 in. fil-
ters, and unit casing. See table at right for factory-supplied filter
pressure drop.
3. Refer to fan motor and drive tables for additional data.
