| description | An inside-out reverse flow air filter element (
20
) has a resiliently compressible molded lower end cap (
48
) having molded drainage surfaces including a molded raised central dome (
72
) shedding moisture radially outwardly and downwardly, a plurality of molded drainage holes (
70, 74, 76, 78
) spaced radially outwardly of and below the top of the central dome, and a plurality of radial segments (
98, 100, 102, 104, 110, 112, 114, 116
), an annular trough (
80
) and tapered slope surfaces (
82, 84
) providing desired drainage. A mold (
130
) has a plurality of upstanding segments (
136, 138, 140, 142
) having posts (
144
) and ramps (
146
) forming the drainage structure, and locator faces (
152
) engaging, guiding and locating the annular filter media (
34
) in the mold. |
