Review on SM550 Universal Bathroom Vent Fan Motor Replacement Kit - Compatible with Nutone Broan - Efficiently Replace C01575, 65100, EM550, EM750 - 50 CFM120V Electric Motors Included by Brian Carrizales

Had trouble finding a motor that came with fan blades and fairing that fit my old bathroom. It worked. Just had to buy nuts that worked with the bolts because the old ones had rusted and reuse the old metal case. Newer models had a metal body that was either too small or too big. I didn't want to cut a hole to fit the case! The noise level is no higher than my old one.
