Intake and Exhaust Vents. Ideal for use in 'rain screen' systems. Removable damper, cut away screen option and built-in drip edge. For use with 4" ducting. Manufactured of UV protected polymer resin.
There are a bunch of chintzy looking bath fan hoods out there. This one is unusual in that it appears thought went into the design. Air doesn't like to make abrupt turns. This hood is effectively curved to allow the air to flow out smoothly. Thought went into the design of the water protection as well. And, surprisingly, birds like to flip open the dampers on hoods like this and nest inside the ducting. That is certainly not good for the air flow. The bird screen (and the backdraft damper) on this hood can be removed if the system is going to run continuously because anything in the way of the air flow will reduce it. The damper itself is tighter and better fitting than most.
