Self Cleaning Filters - Rotating Scraper

HD process supply self-cleaning wedgewire filters with motor-driven rotating screens and scraper gate (the FX range), suitable for separation of suspensions and continuous removal of particles.

The Wedge Wire Strainer Filter is a versatile, self cleaning filter for fluid media with a minimum of maintenance. The robust Self Cleaning Wedge Wire filter with its motor-driven cleaning device suitable for the separation of suspensions as well as the continuous separation of solid particles from liquids whose viscosity's may range from water-thin to highly viscous products such as honey. These offer a wide range of application possibilities throughout the entire processing industry

  • Filtration with most liquids, filtering from 35 micron to 3 mm aperture.
  • Available with automatic purge system.
  • Can be set up for to differentiate the purge effect between lighter (floating) and heavier (sinking) waste particles


The liquid flows from the outside to the inside of the wedge wire screen and leaves the filter housing through the higher placed exit. Between lower placed entrance and the upper exit a seal is placed, limiting any cross contamination between lower (dirt) part and upper (clean) part. Dirt and particles are retained on the outside of the screen and are continuously removed from the filter element with a flexible scraper blade. The dirt is directed to the sump by a laminar flow in the filter and collected in the bottom part of the filter housing. This collection chamber may be purged either manually or automatically through a valve. An automatic purge system can be set up including an actuator and a time controller or pressure differential initiated valves. The installation of a manual by pass function is advised. Liquid losses are limited. Clogging of the filter is almost impossible, because of the special construction of the wedge shaped filter element wires.
