  • 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.

    2 questions. Can the L500k be wall mounted? Can the 10" round duct be reduced to 8" without effecting performance?

    Asked by: steve
    Thank you for your question on the model L500K kitchen ventilation system. The L500K can be installed in a ceiling or a wall (as long as you have enough depth). The duct adapter coming off of the unit is 4-1/2” x 18-1/2”. You can keep the duct work this size or convert it to 10” round. You cannot use anything smaller than 10” round.
