    Broan 688-h/663-h Sones

    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 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.

    Answers

    Answer: 
    Thank you for your question. Broan model 670 is made to be used with 3" ducting. If you have 3" rigid duct, you can expect to achieve the rated CFM within approximately 13 feet. Each 90 degree 3" elbow is equivalent to 3 linear feet and is not considered in this figure. Please contact our Technical support group at 800-637-1453, if you intend to use a non specified duct size.
