Abstract:
1. A fat or grease filter, comprising: a cartridge assembly that is removably attached to a tube assembly, the cartridge assembly includes at least one helix assembly that is adapted to be received in an associated tube of the tube assembly, the at least one helix assembly located inside the associated tube defines a first helical air path between an inlet located at an upper front side of the tube assembly and an equalizer manifold, and a second helical air path between the equalizer manifold and an outlet located at an upper back side of the tube assembly, the second helical air path being located on an opposite side of the at least one helix assembly in the associated tube from the first helical air path, the equalizer manifold directs the air flow from the first helical air path to the second helical air path, wherein centrifugal force created by rotating air within the first and second helical air paths is adapted to cause fatty particles to separate from the airstream and stick to an inner wall of the tube.
