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.

Rated 3.5 out of 5 by 2 reviewers.
Rated 2.0 out of 5.0 by Ok product except there is no way to remove lint from the screen. My dryer ran literally two loads before needing to be disconnected and the screen emptied or else the clothes were still wet after an entire cycle. Ridiculous design! October 25, 2016
Rated 5.0 out of 5.0 by Good sturdy product No pre-drilled holes to fasten vent to outside wall, but very sturdy. July 14, 2015
