Wedge wire screen is a welded vee wire stainless steel construction mainly used for filtration, separation and retention of media. It is made of surface profiles, usually V-shaped (wedge 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 filtering flow is determined by the position of the surface profiles in relation to the support profiles. Wedge wire tubes are either flow out to in (FOTI) or flow in to out (FITO). Almost all shapes and sizes can be developed according to the customer’s requirements, starting from two basic forms: Overview:Wedge Wire Technology and Profiles
