99080166 BP28 Bathroom Fan Motor Replacement Kit - 2 Pack

In this review the 99080166 BP28 bathroom fan motor replacement kit is evaluated for homeowners and DIYers who need a straightforward swap for an older or noisy exhaust fan. The two-pack offers a practical, lower-cost option for restoring ventilation to small bathrooms, and the single biggest reason to buy is fit and functionality: these motors are built to match common Nu-Tone and Bro-an style housings and deliver the rated 70 cfm airflow while running on standard 120V household power.

Key Features

• Electrical rating: The motor runs on 120 volts at 60Hz and draws 1.4 amps, so it plugs into standard household circuits without extra wiring changes.
• Performance: With a 70 cfm airflow and 3000 rpm speed, it moves sufficient air for most small bathroom exhaust applications to reduce humidity and odors.
• Compatibility: The BP28 design fits a range of ventilation models including 671, N655 and N679 series, making it a drop-in option for many older units.
• Physical fit: Shaft measures 7/32 in x 1-1/4 in with a flat and a 7/8 in stack, giving a reliable mechanical match to original blower wheels.
• Convenience: Each motor includes a 6-1/2 in wire with a 2-prong plug for simpler reconnection during replacement.
• Value pack: Sold as a 2 pack, it covers two fixtures or provides a spare at a lower cost than buying single replacements.

Who It's For

This kit is best for homeowners, landlords, and handymen who need a cost-effective replacement for older Nu-Tone or Bro-an style bathroom fans and who are comfortable cutting power and swapping a motor assembly. It suits small to medium bathrooms where a 70 cfm motor provides adequate ventilation and where the original motor used a similar shaft and plug configuration.

It is less suitable for buyers who require ultra-quiet operation, specialized mounting brackets, or motors with different electrical ratings. If a bathroom needs higher airflow than 70 cfm or a specific manufacturer warranty, consider a different, higher-capacity or brand-specific model.

Pros & Cons

Pros

• Good value as a two-pack, saving time and money for multiple fixtures.
• Direct compatibility with many common ventilation models, reducing modification needs.
• Solid airflow and motor speed that restore effective ventilation.
• Simple 2-prong plug and standard electrical rating for easy installation.

Cons

• Some users may find the motor louder than modern low-noise designs, so it is not the quietest option available.
• No specialized noise-dampening features are included, so additional mounting care may be needed to minimize vibration.

Specifications
