Upgrade 8664RP 8663RP Nutone Bathroom Fan Motor 100CFM Copper

Description

Product Overview

The Cylrod 8664RP/8663RP motor is engineered as a premium upgrade for Nutone and Broan bathroom exhaust fans. Constructed from high‑grade copper, the motor offers superior thermal conductivity and durability compared with the original aluminum designs used in many OEM units over a decade ago. With a rated airflow of 100 CFM, the motor efficiently removes moisture, odors, and airborne particles, helping to maintain a healthier indoor environment. The unit operates at a quiet 3.5 sones, delivering a low‑noise experience that is ideal for residential bathrooms, guest suites, and commercial washrooms where comfort and discretion are paramount. Dimensions of 9.72 × 9.53 × 5.43 inches and a weight of 3.22 lb make the motor a compact yet powerful solution that fits seamlessly into existing fan housings without the need for additional modifications. The motor’s electrical specifications align with standard 120 V AC household wiring, and the included wiring harness simplifies the connection process, reducing installation time to roughly ten minutes for most users.
