Telescopic Downdraft System
The telescopic downdraft is a venting alternative to a range hood installed over a cooktop. When not in use the downdraft vent retracts down into the cabinet, leaving only a thin hinged cover showing. When needed it rises to a level about even with the top of most pans.
This type of vent is ideal when the cooktop is installed in a kitchen island or peninsula, and can be installed behind most gas sealed burner cooktops and electric smoothtop and induction cooktops.
