  • Is this unit rated for grease?

    Technical support recommended this vent to me as a option for my kitchen ventilation. Is this rated for grease? I don't see it noted in the specs.

    Please advise for above a kitchen island with induction.

    We don't need the makeup air duct, because we have our windows open all the time in Hawaii. We can't hang a traditional hood above our island, so we love this approach. We do want to have a grease filter (because this is a kitchen). Is this our best model? Or, will the L300KMG do the trick? We couldn't find a grease filter for the L300KMG.
    Asked by: JaHaa
    Aloha and thank you for your question! The L300KMG is designed for kitchen application and uses a metal grille and blower wheel. It does offer an optional aluminum filter model number LAF1. Should you have further questions about your particular installation, please contact Technical Support at 800-637-1453. Thank you for your interest in Broan ventilation fans!

    Can the L500KL be installed on the wall rather than ceiling?

    We have very high cathedral like ceiling and need filtration in the kitchen area of an open concept home.
    Asked by: Scottee
    The Broan L500KL can be mounted in the wall (size permitting) If you have any questions about your installation please contact Technical Support directly at 800-637-1453.
