Why use wedge wire screen products in various fields

Wedge wire is a welded steel structure, mainly used for filtration, separation and retention media.

It consists of surface profiles, usually V-shaped or wedge wire, that are resistance welded onto support profiles or suport bar. The distance between the surface profiles is controlled very accurately, as it forms the slot through which the filtrate flows.

In case of V-shaped surface profiles conical slots are created

The wedge wire screen has two filtrations direction

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)

Advantages of wedge wire products

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: precise slot sizes are available to meet customer´s requirements.
Surface filtration: the V-shaped surface wires allow easy cleaning by mechanical scraping or back flushing.
Low pressure-drop
Strong construction: for most applications, the wedge wire screen is self-supporting, because of the welding at each intersection.
