Filter arrangements for liquids and methods of use
A filter cartridge has media construction, a housing, and a first end construction. The first end constructions includes an outer radial wall with circumferentially spaced connecting sections; each connecting section having a plurality of helical profiles extending at a helix angle. The filter cartridge is removably attached to a filter head, which has mating connecting segments. A bowl cartridge assembly is also provided including connecting sections with a plurality of helical profiles.
1 . A method of servicing a filtration assembly including a filter cartridge mounted on a filter head; the method comprising:
(a) providing a filter cartridge having alternately circumferentially spaced connecting sections and non-connecting sections surrounding a filter media construction;
(b) mounting the filter cartridge on the head by pushing the filter cartridge axially and rotating the filter cartridge less than 90° to engage the connecting sections of the filter cartridge with connecting segments on the filter head; and
(c) while rotating, compressing a seal member on the filter cartridge to form a seal between and against the head and the filter cartridge.
2 . The method of claim 1 wherein the step of providing a filter cartridge includes providing a filter cartridge having smooth non-connecting sections, each of the non-connecting sections being equally spaced from each other.
3 . The method of claim 1 wherein the step of mounting the filter cartridge on the head includes rotating the filter cartridge until a stop member is engaged to prevent further rotation.
4 . A method of servicing a filtration assembly including a filter cartridge mounted on a filter head; the method comprising:
(a) providing a filter cartridge having connecting sections; each connecting section having a plurality of helical profiles extending at a helix angle; and each of the helical profiles within each connecting section has a different cross-sectional shape from at least one other helical profile within a respective connecting section; the connecting sections surrounding a filter media construction;
(b) mounting the filter cartridge on the head by pushing the filter cartridge axially and rotating the filter cartridge less than 90° to engage the connecting sections of the filter cartridge with connecting segments on the filter head; and
(c) while rotating, compressing a seal member on the filter cartridge to form a seal between and against the head and the filter cartridge.
5 . The method of claim 4 wherein the step of mounting the filter cartridge on the head includes rotating the filter cartridge until a stop member is engaged to prevent further rotation.
6 . The method of claim 4 wherein the step of rotating includes rotating the filter cartridge until a click is detected by a person conducting the method.
7 . The method of claim 6 wherein the click is one or both of an audible click or tactile click.
8 . The method of claim 6 wherein the step of rotating until a click is detected includes rotating until detents on the filter cartridge are received within detent recesses in the head.
9 . The method of claim 4 wherein the step of mounting includes aligning an outlet opening of the head with a grommet seal member on the filter cartridge.
10 . The method of claim 4 wherein the step of rotating includes rotating the filter cartridge until a stop member is engaged between the filter cartridge and the head.
11 . A method of servicing a filtration assembly including a filter cartridge mounted on a filter head; the method comprising:
(a) providing a filter cartridge having connecting sections; each connecting section having a plurality of helical profiles extending at a helix angle; and within each connecting section, a first of the helical profiles being different from at least one other helical profile based on one or more of: profile shape, axial spacing, or axial depth; the connecting sections surrounding a filter media construction;
(b) mounting the filter cartridge on the head by pushing the filter cartridge axially and rotating the filter cartridge less than 90° to engage the connecting sections of the filter cartridge with connecting segments on the filter head; and
(c) while rotating, compressing a seal member on the filter cartridge to form a seal between and against the head and the filter cartridge.
12 . The method of claim 11 wherein the step of mounting the filter cartridge on the head includes rotating the filter cartridge until a stop member is engaged to prevent further rotation.
13 . The method of claim 11 wherein the step of rotating includes rotating the filter cartridge until a click is detected by a person conducting the method.
14 . The method of claim 13 wherein the click is one or both of an audible click or tactile click.
15 . The method of claim 13 wherein the step of rotating until a click is detected includes rotating until detents on the filter cartridge are received within detent recesses in the head.
16 . The method of claim 11 wherein the step of mounting includes aligning an outlet opening of the head with a grommet seal member on the filter cartridge.
17 . The method of claim 11 wherein the step of rotating includes rotating the filter cartridge until a stop member is engaged between the filter cartridge and the head.
