If you want Exhaust CFM Fan energy, then?I believe you need to specify Exhaust CFM.

OK, eQuesters,?I think I have this straight. If you specify an Exhaust CFM LESS THAN OSA CFM, nothing airwise changes, and Exhaust CFM translates to an Exhaust?fan HP. If Exaust CFM EXCEEDS OSA CFM, the OSA CFM is increased to account for no negative airflow. And Exhaust CFM STILL creates and Exhaust HP.
