A fume hood, which comprises a plurality of peripheral inclined drainage channels for receiving condensed grease that is gravitationally delivered thereto from a region of the fume hood thereabove. One of the drainage channels continuously extends into an adjacent drainage channel therebelow to provide a single passageway that delivers the received grease to a single grease collection hole. Each of the drainage channels comprises a surface along which the received grease flows and which slightly extends inwardly into a hood interior from a bottom edge of a corresponding wall of the hood, and a border element which extends vertically above an inward edge of the drainage channel surface to a sufficient height which prevents the flowing grease from spilling into the hood interior. |
