Wedge wire

The wedge wire technology is a very specific production method, used to manufacture filter elements. It is composed of a series of parallel triangular-shaped profiles, that are welded perpendicularly on support profiles. Learn more about this technology here.

Product Title

Slot tubes

Wedge wire can be constructed in a cylindrical shape. There are different tube designs that are useful in a wide variety of applications. Discover them here.

Product Title

Radial external wire

These tubes are composed of a surface profile wire that is spirally wrapped around axial support profiles and attached to each other by resistance welding.

Product Title

Radial internal wire

For these types of slot tubes, the support wires are on the outside in an axial direction and the profile wire runs radially on the inside of the tube. The flat side of the triangular profile wire is oriented to the inside of the tube, which is why this element is FITO (= flow in to out).

Product Title

Axial internal wire

This type of filter tube is characterized by an axial profile wire/axial slot direction. The support wire is oriented on the outside of the filter element in a radial direction. The smooth surface of the profile wire is on the inside and the filtration direction is therefore from the inside to outside. Although FOTI is also possible in exceptional cases.
