PLUG PLAY CONVENIENCE - Built-in on/off switch on cover means zero extra wiring—control at your fingertips.
The Broan-NuTone 509S is a high-efficiency through-the-wall ventilation fan delivering 200 CFM airflow with a quiet 8.5 sones noise level. Featuring a built-in on/off switch, galvanized steel housing, and an easy twist-lock motor assembly, it installs quickly without ducting. Designed for rooms up to 195 sq. ft., it offers durable, weather-resistant performance with a sleek white finish and adjustable fit for walls 4.5" to 9.5" thick.
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.

A good exhaust fan for high humidity indoor pool area
I have two of these in an enclosed swim/spa area attached to our home. Over years, the humid environment caused one of them to stop working. I replaced both of them, at the same time, using the same model. I re-used parts of what was already installed, such as the thru-wall ducting, and exterior vents, but I replaced the worn springs on the vent baffle with the new ones, and all of the internals. These were a great deal from Amazon, though one of the units which I purchased had been returned and didn't have all of the mounting parts. A quick call to Broan, though, and they were able to send just the missing parts with no hassle so I didn't have to return everything to Amazon. Good performance, and I hope another several years of life out of these new units.

Decent product, but very loud
It does what it is supposed to do. Install is very straightforward. Yes, it is loud, but it is hard to find through the wall fan.

The exact solution I was looking for.
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.

Works ok
Moves a lot of air as advertised. Installed in kitchen with dial switch to operate. Could originally use on slower speeds which was nice to reduce noise. Has gotten gunked up even with grease screen and the flap only opens on full blast. Takes a few seconds for the flap to open. Would have to climb a ladder to the second story to clean so that it works again at lower speeds. Didn't take long to have reduced function so I'm debating whether it is worth it. We'll see if maybe I can spray it with something. Don't want to get into adjusting the spring and end up with an air leak. Maybe a little bit more powerful motor would be a benefit.

Powerful suction
Used this to replace a wall vent in an old kitchen. It's much more powerful than expected so it's rather loud, but it moves a ton of air. The on off switch makes it easy to use, I just wish there were power levels for the times jet levels of air movement aren't needed.

Bad bad bad bad bad = MAD
Update # 2= EVERYTHING about this is a LIE. No where near 180 CFM (maybe 1/10th os that, Loud, and draws over 6 amps (not claims of 1.5) - Horrible unit, horrible company. ALL LIES. Original comment = Badly advertised, Badly designed. NOT at all what I expected. After having cut a large hole in my wall I have no choice but to continue ATTEMPTING to install it ... That is if I can manage to get it reassembled - Absolutely horrible 'design' (alleged) for attaching (theoretically) the electric junction box to the unit. Three attempts to figure this out have gotten me absolutely NO where. Current thinking is I'll be forced to resort to lots and lots of duct tape and/or do without the idiotic alleged junction box all together. Instructions (so-called) are zero 'help' whatsoever in this regard - 95% BS. BTW, you'll have to disassemble it before attempting to reassemble. And I still don't know if it even works at all, much less well, much less quietly, Also be prepared for an ugly black box protruding from your house (NOT pictured or described at all). Update #1 = as a professional product designer I must say that this is one of the very WORST products I've ever had the displeasure to encounter. It does 'work' - sort of - its loud and no where near the suction expected. On top of all of the above, it draws 6 Amps (720 Watts) or over 17 kWh/day - R U F'ing serious? This is total POS.

Well built.
Well built. Heavy duty. Moves a lot of air. The only issue I have is it's volume.
