Grease removal apparatus, systems and methods
A filter assembly includes a filter pad comprising fibers including natural, synthetic and/or hybrid fibers. A stabilizer frame formed of a non-metallic material may be imbedded in the filter pad. The stabilizer frame may be configured to provide support to the filter pad to maintain the filter pad in a generally flat configuration. In accordance with a particular embodiment, the filter pad may be comprised of at least first and second fibrous mats that are coupled together. In this embodiment, the stabilizer frame may be disposed between and coupled with the first and second fibrous mats.
1. A filter assembly, comprising:
a filter pad comprising fibers selected from the group consisting of wool fibers, wood-based viscose fibers, and cellulose-based synthetic fibers, the fibers configured to absorb grease particulates;
a stabilizer frame embedded in the filter pad, the stabilizer frame being configured to provide support to the filter pad to maintain the filter pad in a generally flat configuration; and
wherein the filter pad is formed from a single fibrous mat that is coupled with the stabilizer frame, and wherein each of four edges of the mat are lapped over respective edges of the stabilizer frame.
2. A filter assembly, comprising:
a filter pad comprising fibers selected from the group consisting of wool fibers, wood-based viscose fibers, and cellulose-based synthetic fibers, the fibers configured to absorb grease particulates;
a stabilizer frame embedded in the filter pad, the stabilizer frame being configured to provide support to the filter pad to maintain the filter pad in a generally flat configuration; and
wherein the filter pad is comprised of at least first and second fibrous mats being coupled together, and the stabilizer frame is disposed between and coupled with the first and second fibrous mats.
3. The filter assembly of claim 1 , wherein the fibers include a blend of wool and cellulose-based synthetic fibers.
4. The filter assembly of claim 1 , wherein at least a portion of the fibers are treated with a solution that is fire resistant or fire retardant.
5. The filter assembly of claim 1 , wherein the stabilizer frame is formed of fiber board material.
6. The filter assembly of claim 1 , wherein the filter pad includes a bonding emulsion.
7. The filter assembly of claim 1 , wherein the filter assembly has a total dry weight approximately between 50 and 750 grams per square meter.
8. The filter assembly of claim 1 , wherein the filter assembly has a dry loft of approximately between 5 mm and 55 mm.
9. A filter assembly, comprising:
a filter pad comprising a blend of fibers including wool fibers and wood-based fire resistant viscose fibers within the range of approximately 2-9 denier, the fibers configured to absorb grease particulates and the filter pad further comprising a fire retardant bonding emulsion;
a stabilizer frame embedded in the filter pad, the stabilizer frame comprising a fire treated fiber board and having supports extending between opposites sides of the stabilizer frame, the stabilizer frame being configured to provide support to the filter pad to maintain the filter pad in a generally flat configuration;
wherein the fiber board has a thickness of approximately between 1/16″ to ¾″, and the supports are approximately ¼″ to 1.5″ wide; and
a flame resistant adhesive disposed between the stabilizer frame and the filter pad, and coupling the stabilizer frame to the filter pad.
10. A method of manufacture, comprising:
coupling a filter pad comprising fibers selected from the group consisting of natural fibers, synthetic fibers and hybrid fibers, with a stabilizer frame; and
wherein the stabilizer frame is embedded in the filter pad, the stabilizer frame being configured to provide support to the filter pad to maintain the filter pad in a generally flat configuration.
11. The method of claim 10 , wherein the filter pad is comprised of at least first and second fibrous mats being coupled together, and the stabilizer frame is disposed between and coupled with the first and second fibrous mats.
12. The method of claim 10 , wherein the filter pad is formed from a single fibrous mat that is coupled with the stabilizer frame, and wherein each of four edges of the mat are lapped over respective edges of the stabilizer frame.
13. The method of claim 10 , wherein the fibers include a blend of wool and synthetic fibers.
14. The method of claim 10 , wherein the fibers include viscose fibers.
15. The method of claim 10 , wherein at least a portion of the fibers are treated with a solution that is fire resistant or fire retardant.
16. The method of claim 10 , wherein the stabilizer frame is formed of fiber board material.
17. The filter assembly of claim 2 , wherein the fibers include a blend of wool and cellulose-based synthetic fibers.
18. The filter assembly of claim 2 , wherein at least a portion of the fibers are treated with a solution that is fire resistant or fire retardant.
19. The filter assembly of claim 2 , wherein the stabilizer frame is formed of fiber board material.
