A containment assembly for collecting grease or other effluent that includes a layered composite of effluent filtering and trapping materials in the form of a separation filter, a center filter and a barrier layer disposed in a layered manner. The separation filter and center filter desirably include a polypropylene material and each have a different porosity. The separation filter, center filter and barrier layer may be disposed between a top and bottom spacer layer in a layered manner. The composite may be received within a frame assembly. The effluent containment assembly also may include flashing for deflecting the effluent away from the equipment or other effluent source, an assembly for securing the frame assembly to equipment or other source of effluent at an elevation relative to a roof or other surface to be protected, a pole assembly for holding the composite within the frame assembly, and a windbar assembly for holding the composite together during wind conditions.

A grease filter and collection assembly for roof ventilators and the like includes a frame structure having a generally central aperture through which a grease discharge vent projects when the frame structure and trap assembly are installed surrounding the vent, and a replaceable grease-trapping material is removably secured in the frame structure so that the grease-trapping material is exposed within the aperture for trapping grease discharged from the vent. In a preferred embodiment, the frame structure is assembled from extruded frame members which integrally include a plurality of channels for securing and mounting the assembly for retaining the grease-trapping material within the frame structure. Upper and lower channels accommodate corner connections of the frame members. The frame members have side walls which peripherally enclose the grease-trapping material which is tucked between the upper and lower channel inwardly extending from the side wall.

A grease filter and collection assembly for roof ventilators and the like includes a frame structure having a generally central aperture through which a grease discharge vents projects when the frame structure and trap assembly are installed surrounding the vent, and a replaceable grease-trapping material is removably secured in the frame structure so that the grease-trapping material is exposed vent. In a preferred embodiment, the frame structure is assembled from extruded frame members which integrally include a plurality of channels for securing and mounting the assembly for retaining the grease-trapping material within the frame structure. Upper and lower channels accommodate corner connections of the frame members. The frame members have side walls which peripherally enclose the grease-trapping material which is tucked between the upper and lower channel inwardly extending from the side wall. An additional channel is exteriorly exposed in each of the frame members to enable access to the fasteners and hardware for mounting the collection assembly on a roof or wall through which the vent projects.
