Universal SM550 Bathroom Fan Motor Kit Appliancemate 50CFM

Description

Product Overview

The Universal SM550 motor kit is engineered as a precise, drop‑in replacement for a broad spectrum of 50 CFM bathroom exhaust fans. Manufactured by Appliancemate, the kit includes a high‑efficiency 120 V, 3000 RPM electric motor, a 6‑inch power cord with a 2‑prong plug, and mounting hardware that aligns with standard fan housings. The motor’s shaft measures 3/16″ × 1 3/4″ and the mounting studs are spaced 1 7/8″ on center, ensuring a seamless fit for models such as Nu‑Tone 65100, VFM100, C65878, EM550, EM750, and many others. Constructed from durable, heat‑resistant materials, the motor delivers a steady 50 CFM airflow while operating at a low noise level, making it ideal for residential bathrooms, small commercial washrooms, and hospitality settings where quiet operation is essential.

Usage

This motor kit is designed for both DIY homeowners and professional technicians who need a reliable, quick‑swap solution for under‑performing or failed bathroom exhaust fans. It is perfectly suited for installations in new construction as well as retrofits in existing homes. The 120 V, 60 Hz rating matches standard North American electrical systems, and the 6‑inch wire length provides ample reach to connect to existing wiring without the need for additional extensions. Because the motor operates at 3000 RPM, it maintains strong airflow even when the fan blades encounter resistance from dust or moisture buildup. Users can expect a straightforward installation process: disconnect power, remove the old motor, align the new motor’s mounting studs, secure with the supplied screws, reconnect the wiring, and restore power. The low‑noise design reduces the audible hum often associated with older fan motors, creating a more comfortable bathroom environment.
