    Answer: 
    Thank you for your question on the model 784 exhaust fan. Using four inch rigid duct work you can run the duct 23 feet straight without losing CFM. You would need to reduce that length by four feet for every elbow installed.

    Sone rating for 45 sf bath w/ 8' high ceiling

    I'm having a hard time relating Sone ratings to a known sound. I don't need a super quiet fan nor do I want an annoyingly loud fan, but how audible is a 2 sone fan?

    I've calc'd my CFM to be in the range of 72-96 CFM.

    Thanks

    Answer: 
    Thank you for your question on the model 784 exhaust fan. A sone is a linear sound measurement where two sones are twice as loud as one sone and threes sones are three times as loud as one, and so on. A sone is approximately equivalent to a modern day refrigerator running.

    Answers

    Answer: 
    Thank you for your question on exhaust fans. To find the proper fan for a room you would take the square footage of the room and multiply by 1.07. That will give you the absolute minimum CFM needed for a room with an eight foot ceiling. If you have a 10 foot ceiling, multiply your answer by 1.25, a 12 foot ceiling multiply by 1.5 and so on. The optimum CFM would be 1-1/2 to 2 times the minimum.
