Grease filter assembly

A kit for forming a grease filter assembly for absorbing grease from a grease discharge vent having a duct, the kit comprising:

• a plurality of support rods for being positioned generally horizontally adjacent respective sides of the discharge vent duct, the support rods being greater in length than the respective sides of the duct against which they are to be positioned;
• a plurality of mounting brackets each having a rod-receiving aperture for receiving a respective rod therethrough for supporting the rods adjacent their respective sides of the duct;
• fastening means for fastening the mounting brackets to the support rods for clamping of the mounting brackets to the discharge vent duct to maintain the support rods adjacent their respective sides of the discharge vent duct;
• a plurality of grease absorbing pads freely supportable on top of said support rods and positionable adjacent respective sides of the discharge vent duct;
• and
• pad retaining means for retaining the plurality of pads on the support rods adjacent respective sides of the discharge vent duct.

A grease filter assembly for absorbing grease from a grease discharge vent having a duct, the assembly comprising:

• a support frame for mounting to the duct of the grease discharge vent, said support frame comprising:
• a plurality of support rods for being positioned generally horizontally adjacent respective sides of the discharge vent duct, the support rods being greater in length than the respective sides of the duct against which they are to be positioned;
• and
• a plurality of mounting brackets having means for engaging respective support rods for clamping of the mounting brackets and support rods to the discharge vent duct to support the rods adjacent their respective sides of the duct;
• a plurality of grease absorbing pads freely supportable on top of said support frame and positionable adjacent respective sides of the discharge vent duct;
• and
• pad retaining means for retaining the plurality of pads on the support frame adjacent respective sides of the discharge vent duct.

A grease filter assembly for absorbing grease discharged from a grease discharge vent having a rectangular duct extending upwardly from a roof to prevent grease accumulation on the roof, the assembly comprising:

• four support rods, each for being positioned adjacent a respective side of the duct;
• four mounting brackets each mountable to a respective corner of the duct and each having a pair of flanges for extending generally perpendicularly from adjacent walls of the duct on either side of the corner, with each of the flanges having an aperture for receipt of a respective support rod, the mounting brackets providing a pair of flanges extending generally perpendicularly from each of the walls of the duct when the mounting brackets are each mounted to respective corners of the duct, and the support rods each being supported adjacent a respective side of the duct by receipt of the support rods through the apertures of each of the pairs of flanges extending from respective sides of the duct;
• the support rods each being longer than the width of their respective duct sides, with the portions of the rods extending beyond adjacent duct sides crossing one another at each of the duct corners;
• four grease absorbing pads each supportable adjacent a respective side of the duct on respective pairs of end portions of the rods extending outwardly from the respective duct sides;
• eight retaining clips each engageable with a respective end portion of the support rods and each having a channel for receiving respective support pads;
• and
• four tension cords each engageable with the respective pair of retaining clips engaged at either end of the support rods to pull the pairs of retaining clips toward one another to bias the pads into abutment with respective sides of the duct and prevent the retaining clips from falling off their respective support rods.

A support frame for a grease filter assembly for supporting a plurality of grease absorbing pads in spaced relation from a roof through which a grease discharge vent duct extends, the support frame comprising:

• a plurality of support rods for being positioned generally horizontally adjacent respective sides of the discharge vent duct;
• a plurality of mounting brackets each having means for mounting to respective corners of the discharge vent duct and each having a pair of flanges disposed to extend substantially perpendicularly from respective, adjacent sides of the discharge vent duct disposed on either side of the respective corner, with the flanges each having a rod-receiving aperture for engageably receiving respective support rods for supporting the support rods adjacent their respective sides of the discharge vent duct;
• and
• the support rods being greater in length than their respective sides of the discharge vent duct and having end portions, with the end portions of the support rods disposed adjacent contiguous sides of the discharge vent duct extending beyond their respective discharge vent duct sides and crossing one another, with the crossing end portions of the support rods defining supporting grids at each of the corners of the discharge vent duct for supporting the grease absorbing pads thereon.
