NOTES:
1. Factory shipped motor drive range is 1194 to 1526 rpm. Other rpms require a

field-supplied drive.

2. Static pressure losses (i.e., economizer) must be added to external static pres-

sure before entering Air Delivery table.

3. Interpolation is permissible. Do not extrapolate.
4. 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 horse-
power range of the motor can be utilized with confidence. Using your fan mo-
tors up to the watts rating shown will not result in nuisance tripping or
premature motor failure. Unit warranty will not be affected.
