2. Static Pressure (i.e Filters) must be added to external static pressure before entering fan performance table.
6. Bold data shows the range of air flow rate for unit management system, other rpms require field-supplied drive.

5. Extensive motor and drive testing on these units ensures that the full brake horsepower and watts range of the motor can be utilized with confidence. 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.
4. Fan performance is based on wet coils, clean filters and casing loses.
3. Interpolation is permissible. Do not extrapolate.
1. Do not adjust motor rpm such that motor maximum bhp and/or watts is exceeded at the maximum operatin cfm.
