Wedge wire is a welded stainless steel construction mainly used for filtration, separation and retention of media. It is made of surface profiles, usually V-shaped, that are resistance welded onto support profiles. The distance between the surface profiles is controlled very accurately and forms the slot opening  through which the filtrate flows.

  • The direction of the flow is determined by the position of the surface profiles in relation to the support profiles. Wedge wire screens are either flow-out-to-in (FOTI) or flow-in-to-out (FITO).

Wedge wirehas the following advantages:

  • Non-clogging: the continuous slot formed by the V-shaped surface wires ensures a two-point contact between the particles and the slot, which minimizes clogging
  • High-precision slot sizes
  • Surface filtration: the V-shaped wires allow easy cleaning by mechanical scraping or back flushing
  • Longer life time
  • Low pressure drop
  • Strong construction: for most applications, the wedge wire screens are self-supporting
  • Engineered to high standards
