ABSTRACT:
An apparatus for collecting grease from a kitchen ventilator, which is mounted on the roof of a structure housing a restaurant. The apparatus fits around the exhaust fan of a kitchen ventilator and includes at least one layer of filtering medium which fits snugly about the exhaust fan, a rectangular frame for securing the layer of filtering medium about the exhaust fan, and a plurality of retaining bars for securing the layer of filter medium in the rectangular frame. The rectangular frame is comprised of four frame sections joined at each end with 90.degree. elbows. Each frame section comprises three tubes with supports fitted between the tubes. The 90.degree. elbows fit over and join the tubes of one frame section with the tubes of another frame section. The retaining bars are positioned between two tubes of opposing frame sections, above the layer of filtering medium. The apparatus includes four retaining bars: a pair of which snugly abut the exhaust fan to prevent any movement of the apparatus relative to the exhaust fan during use; and, each of the remainder of which are positioned between one of the pair and one of the non-opposing frame sections to secure the ends of the layer of filtering medium in the frame. Should parts of a frame section be cut out to accommodate an obstruction, reinforcement supports can be fitted between the tubes of the cut-out frame section and adjacent to the obstruction to reinforce the cut-out frame section. The frame of the apparatus can be expanded in two ways to cover and protect a greater area of the roof from grease expelled from the exhaust fan.
