Question: Does this fan include a wall cap for the outside wall?
Document: This describes how I installed a Broan 509 in a cinder-block wall basement, having only 12-inches of vertical relief (clearance between the ground and the aluminum siding at the bottom of the first floor). The outside wall cap / exhaust vent that comes with the Broan 509 Wall Ventilation Fan is enormous; a monstrosity. It was not going to fit. Instead I used the unobtrusive Air King BDD8R Back Draft Damper (8 Inch Round).
I needed a thru-wall vent fan for our log home. This would have been a good choice I believe except it is on the front of the cabin and when received, had a large black metal box located on the front which was very unattractive and would have been an eyesore for sure. My criticism is mainly that the photos shown on the website didn't display this information and although I tried to locate an outside view, it wasn't clear.
I fitted the outside wall with the 11-inch square MV 250/200 VJ ventilation grill (louvered shutters). This assembly (Broan+AirKing+Grill) allowed me to fit the exhaust within the 12 inch height on the outside wall.On the outside, the duct-work was a mere 2 inches above ground level. Place a metal screen behind the louvers on the ventilation grill. This keeps out any curious ground-level bugs. I also placed a gasket between the grill and the stucco wall.
It's a great fan if you are looking to replace old fan .Plenty of power and installation was very easy . Only downfall is outside vent is black , but a can of good spray paint took care of that and it looks great
As far as I can see this fan was made in the USA! Wisconsin in fact. A selling point right there! The operation of the fan is effective. What especially impressed me was the speed of delivery: less than 48 hours after placing my order the packing box was sitting outside my front door!Now for the negative. Amazon raised the price on me.
Since it's an exhaust fan I'm OK with it making enough noise to remind me to shut it off. Installation was fairly easy but the directions could use some improvement. Amazon should also show photos of the outside cover to show what it looks like on that side. We just had the house sided and I really only needed the fan cover and damper, which I had to paint to match the new siding.
Fan works well. I used it to replace old Nutone fan. The Broan was slightly smaller in diameter than the Nutone which helped in the installation. I did not have to make the existing hole larger. Like most through the wall fans this one could be quieter.
We are renovating our kitchen and did not want to remove the old Nutone through the wall fan but rather to replace with a newer model. This replacement fan was the answer. It is hard wired in and did take a little modification but it did the trick. However, there are some cons about this fan. It is much more powerful than my original fan and therefore much more noisy. However, it does move a lot of air in a short period of time.
This is disappointing because something that is so permanent should be made out of metal that can be painted the same color as your wall. I would gladly have paid a few more dollars for metal versus cheap flimsy plastic. All in all it was a good solution. Incidentally, the reason I purchased this fan is because the original fan has been in the home since it was built (40 years ago). The only reason I replaced it was because of its age and obvious rust from years of use.
Not the prettiest but helps suck the air outside when cooking
Answer: yes
