Review on Optimized Blower Assembly by Charley Martinez

My previous exhaust fan started making an unbearable noise and I couldn't find a replacement at any of my local shops. My only option looked like a complete replacement until I stumbled across this fan assembly. There was some concern as to whether this would fit my 683C model. When it arrived it was easy to replace and worked great. I'm pretty sure this build will fit any Broan 680 series.
