When describing wedge wire screen tubes, often mention FOTI, FITO, radial external wire, radial internal wire, and axial internal wire. Some customers feel confused, and we are pleased to make a simple and easy introduction to these parameters.
FOTI means flowing direction from outside to inside.
FITO means flowing direction from inside to outside.
Radial external wedge wire means the wedge wire is radial outside the support wire, and the support profile wire is axial. These wedge wire tubes are composed of a surface wedge wire that is spirally wrapped around an axial support profile wire and attached to each other by resistance welding.
When the flow direction is from outside to inside (FOTI), the flat side of the surface wedge wire is on the outside of the tube.
When the flow direction is from inside to outside (FITO), the flat side of the surface wedge wire is on the inside of the tube.
Radial external wedge wire FITO type is also called a reversed wedge wire screen tube.

Most applications require a standard common type. Precision openings and Economical production | External axial wire with internal circumferential support rods. Optimized collection and distribution replaces perforated inner tubes | Reversed radial internal wedge wire is another name for it. Back washing and Inverted external circumferential |
Radial Internal wedge wire means the wedge wire is radial inside the support wire, and the support profile wire is axial. Radial Internal Wedge Wire Type Tube is rolled-formed from flat wedge wire screen panels, which means there are many welding joining points and the inside wedge wire is not continuously spirally wrapped around axial support profile wires. Furthermore, radial internals only have one flow direction, which is FITO (flow in to out).

| Smooth internal screen surface. Facilitates cleaning with an internal axial-movement scraper. Economical for small quantities and production of any size |
Axial Internal wedge wire means the wedge wire is axially inside the support wire, and the support profile wire is on the outside of the filter element in a radial direction. The smooth surface of the wedge wire or profile wire is on the inside of the filter element, so the filtration direction is from inside to outside. This means that axial internal wedge wire has only one flow direction, FITO (flow in to out), though FOTI (flow out to in) is also possible in exceptional cases.
For axial internal wedge wire, according to different slot sizes and filter sizes, there are two different types: one type is wedge wire type tube or cylinder that is rolled from flat wedge wire screen panels, which means there are many welding joining points. The other type is the outside support wires, which are continuously spirally wrapped around axial wedge screen wires.

Smooth internal screen surface. Facilitates cleaning with an internal axial-movement scraper. The flow moves across the wire edges for effective dewatering. Economical utility | smooth internal screen surface Without a welding seam, more stronger strength Facilitates cleaning with an internal axial-movement scraper The flow moves across the wire edges for effective dewatering |
Axial External wedge wire means the wedge wire is axially outside the support wire, and the support profile wire is on the inside of the filter element in a radial direction. The smooth surface of the wedge wire or profile wire is on the outside of the screen filter element, so the filtration direction is usually from outside to inside. But sometimes, the customers require Axial External Wedge Wire and FITO, which means the smooth surface of the screen wedge wire is inside. FOTI is used when there are no special requirements, such as for an axial external wedge wire. Axial External Wedge The wire tube or cylinder is rolled from flat wedge wire screen panels, which means there are many welding points on the inner supporting profile wires.
