Abstract
A fat or grease filter for a ventilator or exhaust hood is provided, and includes a cartridge assembly that is removably attached to a tube assembly. The cartridge assembly includes at least one helix assembly that is 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 a bottom equalizer manifold connected to the associated tube, and a second helical air path between the equalizer manifold and an outlet located at an upper back side of the tube assembly. The equalizer manifold directs the air flow from the first to the second helical air path. Centrifugal force created within the first and second helical air paths causes fatty particles to separate from the airstream and stick inside the tube.
