Abstract
An additive carrier for a spin-on filter is provided. The additive carrier is positioned at an upstream side of the filter and includes a basket defining an annular body. The annular body includes a concentric opening extending therethrough, a circumferentially extending recess configured to receive and store an additive material and a plurality of flanges extending radially within the recess, the flanges spaced apart in a circumferential direction of the recess to form a plurality of sub-recesses.

An additive carrier for a spin-on filter, the additive carrier comprising:
- a basket defining an annular body, the annular body comprising:
- a concentric opening extending therethrough;
- a circumferentially extending recess configured to receive and store an additive material;
- and
- a plurality of flanges extending radially within the recess, the flanges spaced apart in a circumferential direction of the recess to form a plurality of sub-recesses.
A spin-on filter comprising:
- a support structure including a first end plate at a first end of the structure a second end plate at a second end of the structure, and a central opening formed in and extending though at least the first end plate, the first end of the structure is an upstream end of the spin-on filter;
- a filter medium disposed between the first end plate and second end plate in a substantially cylindrical configuration;
- a relief valve including a plurality of legs, the relief valve at least partially seated in the central opening;
- and
- an additive carrier positioned at the first end of the support structure, the additive carrier comprising:
- a basket in the form of an annular body, the annular body comprising:
- a concentric opening extending therethrough;
- a circumferentially extending recess configured to receive and store an additive material;
- and
- a plurality of flanges extending radially within the recess, the flanges spaced apart in a circumferential direction of the recess to form a plurality of sub-recesses.
