NOTES:
1. Boldface indicates standard operating range.
2. indicates field-supplied motor and drive required.
3. All other numbers indicate field-supplied drive required.
4. Factory shippedmotor drive rangeis 1194to 1526 rpm.Other rpms
require a field-supplied drive.
5. Static pressure losses (i.e., economizer) must be added to exter-
nal static pressure before entering Fan Performance table. See
Table 7 for accessory/FIOP static pressure information.
6. Interpolation is permissible. Do not extrapolate.
7. Maximum continuous bhp is 4.25 and the maximum continuous
watts are 3775. Extensive motor and drive testing on these units
ensures that the full horsepower range of the motor can be uti-
lized with confidence. Using your fan motors up to the wattsrating
shown will not result in nuisance tripping or premature motor fail-
ure. Unit warranty will not be affected.
