  • Broan high capacity fans are an exceptionally quiet solution to continuous ventilation. With their heavy-duty motors, high capacity fans are an ideal solution for conference rooms, public restrooms and other areas in commercial buildings that require ongoing ventilation. Low-vibration and lo-profile, they work quietly without getting noticed.

  • if i reduce the fan speed with a variable speed control like the broan 80L do i also reduce the current draw?

    Asked by: roy
    Thank you for your question on the model L700L exhaust fan. If you use a speed control on the L700L, there would be some reduction of current draw by slowing the speed.

    I asked previously if utilizing a speed control on an L700L would reduce my current draw

    You answered "yes some" Is there any direct correlation between the reduction in speed and the energy used? For instance if I were to cut the cfm down by 50% would I see a corresponding 50% reduction in amperage draw? Thanks Roy

    L700L vs L700

    What are the differences between the model numbers with the L suffix and the non-L suffix? Jeff
    Asked by: Xbanderradio
    Thank you for your question on the models L700L and L700 exhaust fans. The difference between the L700 and L700L is that the L700 has a grille that you would see inside the room you are ventilating and the L700L is designed to be used in an in-line installation where the unit is installed in an attic or crawl space. You would need to install grilles in the ceiling and duct them to the L700L. The installation instructions for both models are available for download through our web site for your convenience.
