Answer: 
FAV's do not have a damper, always open. The Round Wall Vent ( WVA 4) has a gravity damper for exhaust (closed when not in use). Please call MasterFlow Technical Services, at 80-211-9612, M-F 8A-5P EDT for additional information.

I'm considering using this vent as a supply air duct for attic ventilation through a concrete block wall.
I would need to know the NFVA to make an informed decision.
