509 Through-the-Wall Ventilation Fan White Cover, 200 CFM, 8.5 Sones, 8"

I did a little research before buying this fan. My bathroom was built without a fan in it and there was no way to out one above the existing shower. So the only way was through the wall to the outside. My house was built in 1952 so the walks are thicker. I honestly didn’t look at the instructions that came with it as I already had a plan. Cut out the hole on both sides. Put the outside hood in first. Once that was done I seen that it didn’t go all the way through. I was nervous but once I put the fan in there is holes for this purpose for how ever thick your wall may be. I bought the switch fan and everything turned out great. Super happy with this product and will probably buy another one for my other bathroom. The only down side is the fan is a little noisy but I don’t care my bathroom no longer has any steam in it anymore from the shower.

The Brian -Nu-Tone 509 wall vent was delivered on time, easily installed and works amazing. I will be purchasing this wall vent again in the future.

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. Secondly, the grille is made out of plastic. 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. This goes to show that Nutone made quality products. The price was good and included shipping.

Works great I think these fans are really good for removing heat and smoke from the kitchen area where an over the stove fan is not possible.

I bought this fan to go through the wall of an exercise room I use with my wife. It can get pretty humid in there especially in the summer. The fan works well, Is reasonably quiet and was simple to install if you are comfortable with basic wiring and construction. Broan customer service can help you determine if you are buying the rigt size fan for your application. I tapped off an existing 120v outlet and brought power to a fan wall timer and speed control on a 2 gang box. I can adjust the speed of the fan and the duration it stays on. I could not use a ceiling fan in my situation so through the wall is a nice alternative. The fan comes with a self closing external damper to keep weather out. They even make a model with a built in switch if you need it. I had to go through a 12 inch cinderblock wall and then my studwall but is was easy and inexpensive to extend the length of the fan sleeve with off the shelf 8" round duct from a big box diy store.

Got this to replace a much older model (like 1950-70s) above my stove. Was hoping the parts were compatible as the size and brand were the same, however in the update they changed everything, including the distance between the screws on the bracket, the size and location of the junction box, and the size and orientation of the ducting, which impacted how it fit in the hole left behind when I removed the old one. It's not the easiest thing to install. The junction box is built in such a way that you couldn't possibly install it with knockout cable clamps already inserted. So I had to install the junction box and wiring BEFORE installing the fan box and ducting, and then put the whole thing into the wall after that, which is the opposite of what they tell you to do and was only possible because the wall was partially opened so I could install the cable clamps half through the hole in the wall. It might have been possible to use push in connectors to that purpose, but I'm not 100% sure and you'd have to thread the push-in backwards onto the cable before snapping it into the knockout, an uphill fight that could damage the cable. So still not ideal. They should definitely rethink that part of the design. The installation instructions were also not superb and as described above, not actually compatible with reality. But once I finally got the thing in there it works fine. So if you're the installer, you'll hate it, from just the homeowner perspective you probably won't. As other reviewers have said, it's very loud, but I got a compatible fan dimmer switch and that makes it very reasonable.

Works great

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). Note: you have to remove a couple of Air King rivets to make it slip over the Broan duct-work. 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. Slightly slope the duct-work downward, from-inside-to-out, just in case you get a heavy rain and water backs up into the duct-work. On the inside, use a plywood spacer between the flange on the Broan duct-work and the inside wall. This gives you the option to 'wedge cut' the spacer to make up for basement walls that are not straight, and for sloping the duct-work downward as mentioned above. Attach the Broan duct-work to the plywood spacer using small L-shaped brackets. Finally, it's nice to Thompson waterseal cuts you make in cinder-block walls, and to fill the inside of the cut cinder-blocks with Stuffit. I temporarily inserted a segment of 8-1/2 inch diameter duct-work into the hole (well-oiled) before stuffit-ing the inside of the cinder-block. Note: the Air King has a ridge making it about 8-1/2 inch diameter. After drying, I removed the temporary duct-work and inserted the finished Broan + Air King assembly. This stops any water seepage, and I can now easily remove the entire assembly should any future fixin' be called for, simply by unscrewing the plywood spacer from the basement wall.

DEL ARTICULO TODO BIEN, GRACIAS PERO EN LA ENTREGA SI FUE COMPLICADO, LO REGRESARON DOS VECES, ASI QUE SE VOLVIO A COMPRAR Y HUBO NECESIDAD DE CAMBIAR DOMICILIO, PERO BUENO, FINALMENTE TENGO EL PRODUCTO EL CUAL ERA URGENTE POR CUESTION DE CONSTRUCCION.

The exterior vent hood is great. Very sturdy and the damper works really well. I had to improvise an 8” piece of duct work to reach all the way through the wall (block, framing and insulation).

As described

The instructions, as with most things, are inadequate. For anyone installing this fan, to get it into the round hole with the electric box seemingly sticking out, you take off the plug, fittings and box and install them once the fan is in the hole. a bit awkward but doable. I think everything now is too expensive. A fan is really simple.

I bought this 8” fan originally by mistake. When I found out it would cost > $30 to return I decided to keep it and install it in my shop as a vent. I’m glad I did. It works great and pushes a ton of air.
