Abstract

The disclosure describes a filter cartridge for removing particulates from a destructive fluid such as a hot acid or solvent. The filter cartridge comprises a cylindrical filter arrangement having a generally annular cross section and including a cylindrical, microporous fluoropolymeric filter for removing the particulate contaminants as the corrosive fluid flows through the filter. The filter arrangement also includes a cylindrical fluoropolymeric structure coaxially disposed adjacent the filter for supporting the filter. The filter cartridge further includes first and second impervious fluoropolymeric end caps concentrically disposed adjacent the first and second ends, respectively, of the filter arrangement. The first end cap includes a central aperture communicating with the center of the filter arrangement.
