Support Tubes
General
support tube with round wire (1 spiral) surface profile
If the slot tubes are used as a carrier for another filter medium for example textile. The surface profile can be:
- reversed triangular
- round
- diamond shaped
In case of round wire the support tubes can be welded with 1, 2 or 3 wires next to each other.
Trislot® Advantages
Compared with conventional support elements ( such as perforated tubes, wire mesh, ....) Trislot® support elements have following advantages:
- a smaller contact between the support tube and the filter media there is more active filter area, which creates a larger active filter media and a smaller pressure drop. Thorough cleaning by back flushing possible.
- a strong mechanical construction
- large open area
- easy to clean (back flushing)
Standard constructions of support tubes (special geometries on request)
The construction of a support tube is described as follows:
surface wire / support wire x number of support wires.
Example: 0,8/2 x 18
This means that the profile wire is Ø 0.8. The support wire is Ø 2 and there are 18 support wires, equally spaced over 360°.
