    Trying to uprgrade 688-h/663-h

    Looking at upgrade kits for 688-h/663-h for home built in 1989 that is rated at 50cfm and 2 sones. Was looking at broan 690 which states sound reduction up to 50% but it is listed at 3 sones? Is that correct? My current fan sure is noisy, so would this "upgrade" be noisier?

    Answer: 
    Thank you for your question on the Broan model 688-H/663-H. A number of years ago, HVI (Home Ventilating Institute) changed the way they rated all fans for sone levels. This fan may have been originally rated at 2.0 sones, but when HVI changed their procedures, the sone rating changed to 4.0 sones. Our fans did not change in any way, only their procedures for testing the fans for sones changed.
    The 688-H would be compatible with the 690 upgrade kit. The 688 is now rated at 50 cfm's with 4.0 sones. The upgrade kit will give you 60 cfm's with 3.0 sones. If you have further questions, please contact Technical Support at 800-637-1453.

    Thank you for your question on the model 688J exhaust fan. The 690NT will work inside the 688 housing. Please contact the Technical Service Department at 800-637-1453 for assistance.

    Broan 688-h/663-h Sones

    Customer avatar

    Seeking Quiet
     on 688
    We have a (probably) 25 year old Broan 688-h/663-h in our shower that sounds like a jetliner every time it runs. The housing lists it at 50 CFM and 2.0 Sones, which seems impossible. I'm looking at replacement fans with the same housing size, but every one I've found has higher listed Sones (3.5-6.0). Do you have any suggestions for quieter replacements or perhaps adjustments/repairs that could be made to the existing fan to help it run at 2.0 Sones as indicated? Thanks.

    Answer: 
    Thank you for your question on the model 688-H/663-H exhaust fan. For a quiet and strong fan replacement that is easily done from the room side, check out model EZ80N made for NuTone distribution. The design of this model allows you to remove your old fan, connect to your 3" duct and connect to your existing wiring all from inside your bathroom.  Please contact the Technical Service Department at 800-637-1453 with questions.

    Answer: 
    Thank you for your question on the model 671 exhaust fan. Using three inch rigid duct work, you can run the ducting approximately seven feet straight. An elbow would equal approximately three feet of duct.

    Answer: 
    Thank you for your question on the model 688 exhaust fan and 678 exhaust fan/light. You can upgrade from a 688 to a 678 but you would need to completely remove the 688 from the ceiling to replace it with the 678. You would also need to enlarge the hole in the ceiling and replace the three inch duct work with four inch. Please contact the Technical Service Department at 800-637-1453 for further assistance.
