$46.52

  • 【Universal Compatibility】Works as a direct replacement for most 50 CFM bathroom fan models. Replaces motors like SM550, VFM100, Nutone C65878, C01575, Sears 569, Bay Motors, Ventorola E498-1, Dayton, Uppco and many more. This broad fit ensures a hassle-free swap-in for homeowners.
  • 【Powerful 50 CFM Ventilation】Delivers strong 50 CFM airflow at 3000 RPM to quickly clear steam and odors. (50 CFM meets or exceeds standard building code requirements for bathroom exhaust.) The 0.29 A motor provides efficient performance while using minimal power.
  • 【Ultra-Quiet Operation】Designed for whisper-quiet performance. The precision motor runs smoothly so you’ll barely hear it – even compared to older fan motors. Users report the fan “worked perfectly… very easy to install so much quieter now!” Enjoy a peaceful bathroom atmosphere without annoying fan noise.
  • 【DIY-Friendly Installation】 The kit includes the motor, blower wheel, and plug, ready to install with no special tools. The pre-wired 2-prong plug simply fits existing wiring. Many customers note it installs “in seconds” and made fixing a 20–30+ year-old fan simple. Clear instructions and a direct-fit design mean you can do it yourself and save on repair costs.
  • 【Durable ABS Construction & 3-Year Warranty】Built with high-impact ABS plastic housing and metal components for long life. ABS is lightweight yet extremely tough and corrosion-resistant, so this motor withstands humidity and years of use. Plus, a 3-year factory warranty on all parts provides extra peace of mind.

Quiet, Efficient Ventilation

Upgrade your bathroom with a virtually silent fan. The SM550 motor’s streamlined design minimizes vibration and sound, so it quietly pulls moisture out of the air. You get full 50 CFM performance without the racket – perfect for early-morning showers or late-night use. (In fact, building codes require at least 50 CFM for bathrooms, and this motor meets that standard while running whisper-quiet.) Its powerful airflow rapidly clears fog and humidity, making your bathroom more comfortable and preventing mold.

Broad Compatibility with Most Brands

Our universal fan motor fits dozens of popular bathroom vent fans. It replaces legacy models from Nutone, Broan, Sears, Dayton, Bay Motors, Ventorola, Uppco and more. The SM550 kit is engineered to match the original mounting and wiring on these units. No need to buy a whole new fan – simply swap this motor into your existing grille or housing. This means you can extend the life of older fans and save money. A quick check of the model numbers on your old motor will show this SM550 as a compatible replacement.

Easy DIY Installation

Designed for homeowners and DIY enthusiasts, installation is straightforward. The motor comes pre-assembled with a blower wheel and a standard plug, so you just slide it into the old fan’s bracket and plug it in. No special tools or electricians needed. Many users report completing the swap in minutes: “It took seconds to install. I’m really happy with it…”. Clear instructions guide you step-by-step. Even if you’re not very handy, this motor’s plug-and-play setup and direct-fit studs make replacement painless. You can enjoy brand-new fan performance without the high repair bill.

Built to Last – Durable Design & Warranty

This replacement motor is made for longevity. Its housing and blower are crafted from sturdy ABS plastic – a material known for strength, impact resistance and corrosion resistance. That means the fan endures hot steam, humid air and regular use without cracking or rusting. Every motor is tested to strict quality standards before leaving the factory. Plus, we back it with a full 3-year warranty on all parts. This long warranty underscores our confidence in its durability. You’re protected against defects and can be sure the fan will keep your bathroom ventilated for years to come.
