Performance shown is for roof ventilators for installation type A: Free inlet, Free outlet. The power rating (BHP) does not include drive losses. Performance ratings do not include
the effects of appurtenances in the airstream.
Sound ratings are loudness values in fan sones at 5 feet (1.5m) in a hemispherical free eld calculated per AMCA Standard 301. Values are for installation type A: Free inlet fan
sone levels. For additional sound data and for selections at other static pressures, please refer to the Optisizer Selection Program.
Due to air stream cooling, the motor loading into the service factor shown does not overheat the motor and is within NEMA recommended limits. BHP at most static pressure
points is less than the maximum power shown - in many cases substantially less. Use Optisizer to see the exact BHP for your selection.
