ABSTRACT:
A back-flushable filter cartridge includes a cylindrical exterior fluid-permeable filter media cage, a cylindrical interior fluid-permeable core element coaxially disposed within the filter media cage so as to establish therebetween an interior space, and longitudinally pleated filter media surrounding the core element and disposed in the interior space such that individual pleats thereof extend substantially radially outwardly from the core element. An annular space is established between outer longitudinal folds of the pleated filter media and the filter media cage. The pleated filter media is radially expandable into the established annular space to allow individual adjacent pleats of the pleated filter media to circumferentially separate from one another in response to fluid flowing in a radial direction from the core element toward the filter media cage.
