*Standard low-medium static drive range is 817 to 1038 rpm. Alternate
high static high static motor drive range is 994 to 1197. Other rpms re-
quire a field-supplied drive.
NOTES:
1. Static pressure losses (i.e., economizer) must be added to exter-
nal static pressure before entering Fan Performance table. See
Accessory/FIOP Static Pressure table on page 52 for more
information.
2. Interpolation is permissible. Do not extrapolate.
3. Maximum continuous bhp is 5.9 and the maximum continuous watts
are 5180. Extensive motor and drive testing on these units ensures
that the full horsepower range of the motor can be utilized with con-
fidence. Using your fan motors up to the watts rating shown will not
result in nuisance tripping or premature motor failure. Unit warranty
will not be affected.
4. Deduct 0.2 in. wg static pressure for high heat units at or above
8000 cfm.
