Abstract:

A grease filter assembly is provided for absorbing airborne grease discharged from a grease discharge vent extending from a roof. A support frame is mountable to the duct of the grease discharge vent and grease absorbing pads are supportable upon the support frame in stationary position surrounding the discharge vent and in spaced relation from the roof. The support frame includes support rods mounted adjacent respective sides of the discharge vent duct and extending beyond their respective duct sides to overlap at the corners of the duct and thereby provide a supporting grid including the end portions of each of two rods extending from adjacent walls of the duct. A plurality of grease absorbing pads are supported on the supporting grid disposed adjacent respective sides of the duct. The pads being of sufficient length to extend beyond the duct sides on both ends so that pads disposed at adjacent sides of the duct overlap one another at the corners of the duct. U-shaped retaining clips are slid onto the ends of each of the rods and have a lower aperture through which the retaining clips are slid onto the ends of the rods, with the edges of the overlapping pads being received in the channel of the retaining clips.

Abstract:

A grease filter assembly is provided for absorbing grease discharged from a spout of a grease discharge vent extending from a roof. A support frame is mountable to the duct of the grease discharge vent and a grease absorbing pad is supportable upon the support frame in stationary position below the spout and in spaced relation from the roof. The support frame includes support rods mounted adjacent respective sides of the discharge vent duct and can extend beyond their respective duct sides to overlap at two corners of the duct to provide a supporting grid including the end portions of each of two rods extending from two corners of the duct. A grease absorbing pad is supported on the supporting grid disposed adjacent a side of the duct. The pad can be of sufficient length to extend beyond the duct side on both ends. U-shaped retaining clips are slid onto the ends of each of the rods extending normal to the side adjacent the pad and have a lower rod receiving portion through which the retaining clips are slid onto the ends of the rods, with the edge of the pad being received in the channel of the retaining clips.
