Abstract
A filtration system includes a filter medium that has two side edges. The filter medium is moveable in a longitudinal direction, and at least a segment of the filter medium is used to filter a fluid. Seals are used to seal the filter medium segment's side edges, and the seals are moveable with the filter medium in the longitudinal direction. Consequently, the seal may not need to be raised or deflated during indexing of the filter medium. Additionally, the indexing of the filter medium does not create wear on the filter medium and seal and does not cause distortion or tear of the filter medium.
