  • Can this be installed in an existing 3" vent pipe using 4" to 3" reducers?

    I only have 25 inches in attic between bath ceiling and underside of roof
    Asked by: Dave
    The ILF120 has been designed to use 4” round duct. Using smaller 3” round duct would reduce the air flow performance of the fan . Please contact our Technical Service department at 888-336-6151 for further assistance

    What is the sone rating on these?

    In my application the power unit will be directly above the bath ceiling, above an existing large grille. Noise will be obvious...
    Asked by: LorenAmelang
    Thank you for your question on the model ILF120 in-line exhaust fan. Since these units are remotely located and are not actually in the room itself, they do not have a sone rating. The ILF120 is a very quiet, smooth running fan and you should not have a problem with noise, even when installed directly above the bath ceiling.

    Can I run a supply duct through a 2X4 wall

    Hi, I'd like to run the supply duct down a 2X4 bathroom wall to my basement where I would mount the inline fan. I see a product called a '4 inch Round to Oval Duct Elbow' that accepts a rigid duct compressed to 3 1/2 inch x 4 7/16 inch oval. The other end of the elbow is a 4 inch round that I believe would accept your grill. Would that be suitable? Do you have any other suggestion for running duct thru a 2X4 wall? Thanks
    Asked by: Brian
    Thank you for your question on the model ILFK120 in-line exhaust fan. The only way you are going to run four inch rigid duct work down a standard 2” x 4” wall would be to flatten the duct work to 3-1/2” thick as it goes through the wall. As long as the duct work is four inch round at the grille or the ILF120, it should work. Please contact our Canadian office at 888-882-7626 if you need further assistance.
