Performance shown is for wall 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 shown 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. Available motor RPM's may vary from table. Supply
performance is obtained by reversing the direction of the venturi.
