  • This patent-pending series marks a revolution of our mid-range ventilation fans. It gives professionals the flexibility to handle new construction or room-side retrofit installations from one hard-working product line with a full range of operating points. Innovations include foldable mounting ears and new damper and housing technology that improve building airtightness like never before. And all with new grille designs that are at home in any decor.

    • 110 CFM reduces humidity to quickly eliminate fogged mirrors and manage moisture in bathrooms up to 105 square feet, so your vision will always be clear and your surroundings will always be comfortable
    • Retrofit installations can be done entirely from the room-side – no attic access required. This means a faster, easier installation, so you can move on to something else
    • With our TrueSeal™ Damper Technology, InVent fans reduce air leakage by up to 50%* compared to competitive models, resulting in better home performance via blower door tests and reducing cold and warm air backdrafts
    • EzDuct™ Connector can be installed room-side with no attic access required, fan housing connection have never been easier
    • UL Listed for use over tubs and showers with a GFCI circuit; so you can capture the steam before it spreads throughout the room by locating your fan exactly where you need it the most

    *Testing reflects total fan housing airtightness. See nutone.com/invent for more details.

  • Replacement for 671RB

    Hi, Can you let me know if this unit is the same size as the 671RB? I need to replace my bathroom fan but don't want to have to cut a larger hole in the ceiling etc. The existing 671RB unit is listed at 90 CFM and 3.0 sones - does it matter that the AN110 is 110 CFM? Thanks so much for your help!
    Asked by: Fan Girl
    Thank you for your question on the model 671RB and AN110 exhaust fans. The 671RB has a housing that measures 9” x 9”. The AN110 housing measures 9-1/4” x 10”. As long as you are using four inch rigid duct work and the length of duct work is 13 feet straight or shorter, you should not have a problem. You need to reduce that distance by four feet for every elbow installed. Please contact the Technical Service Department at 888-336-6151 if you need further assistance.

    Can I just replace the fan and not the entire casing? Nutone 671RB w/AN110

    The casing is so tight in there I can't get it out with out damaging the ceiling. I got just the fan/motor out. Can I just replace that?
    Asked by: Colleen
    Thank you for your question. The 671RB’s housing measures 9x9” square. The AN110 measures 9 ¼ x10”. You will need to replace the housing of the 671RB with the AN110 if you want the AN110 to operate properly. For further assistance, contact our Canadian Customer Service Department at 888-882-7626.

    Will it replace an 8814R Unit B fan?

    Asked by: Rob
    Thank you for your question. The AN110 can be used as replacement for the 8814R; however you will need to change out the entire unit. The AN110 has a larger housing than the 8814R. You would need to enlarge your ceiling cutout from 9X9 inches to 9.25X10 inches for the AN110 to fit properly.
