The Hydropression™ effect makes it possible for a static perforated plate to operate over long periods of time without clogging and becoming blinded.

With Duperon® Perforated Plate technology, the Effector™ plate travel behind a static perforated plate and clears the plate openings—back to front—with a Hydropression™ blast that removes debris without extruding or stapling.  At the same time, front mounted debris skimmers guide the released materials to the surface for disposal.
