ABSTRACT:
An improved fluid filtering apparatus having an inlet, an outlet, a sealed housing, an outer bag within the housing, an inner bag generally concentric to and suspended within the outer bag, a filtering medium retained inside the outer bag and outside the inner bag and a flow path which channels the fluid radially inward through the outer bag, the filtering medium and the inner bag to a channel in a perforated tube which supports the inner bag. The apparatus is designed to permit the fluid pressure to radially compress the filtering medium to substantially increase the filtering effect.
