CA 2140459

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 consists of 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 consisting of 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. Tension cords extend between pairs of oppositely disposed retaining clips to retain the pads in engagement with the support frame and to bias the pads into abutment with respective sides of the duct.
