Abstract
A top-loading filter housing has a spin-on combination cartridge and cover in a unitary assembly. The cartridge is an annular filter medium surrounding a perforated center tube and supported in an imperforate bottom endcap, being joined by potting compound to provide a consolidated structure. An annular seal is retained in a central opening in the endcap and is sized for a sliding fit on a vertical standpipe, centrally supported in the filter housing. The cover portion of the cartridge is a molded, circular, glass-filled nylon plate having a depending peripheral flange threadedly receivable in the open, upper end of the filter housing. The cover includes a central well in which the filter medium and centertube are received, both being secured and sealed by potting compound so that the cover and cartridge may be replaced as an assembly.
