Through-The-Wall Utility Ventilator, 180 CFM, 6.5 Sones
A very fine fan
The Broan 509 is a very fine fan. Couple comments:
- I needed a strong fan with a separate variable speed control. It was easy to find the Broan 512M fan which is advertised as working with the 57W/57V speed control, but the 512M is only 6" and 70 CFM, too weak. It was less easy to find the 509 which is 8" and 180 CFM, and I had to ask to determine whether the 57 speed control works with it, which it does. Broan could do a better job of marketing here.
- The installation instructions say to transfer the initial drill hole from inside to outside, but that's not accurate enough to make the outside fan hole match the inside one, and if they don't match you're in trouble. If I had used the initial drill hole mine would have been off by nearly an inch. To get it right, make the inside fan hole, insert the metal cylinder so it touches the inside surface of the exterior wall, then drill several holes at the circumference and use those to position the outside fan hole.
- Once installed, this fan looks, sounds, and performs very nicely in every way.

Im a fan of this fan
This is a great item. It was delivered quickly. It has a nice heavy vent shroud for outside the house. It mounts easily. It really moves air and is fairly quiet.
