Supporting Tubes

 Construction Drawing

If the slot tubes are used as a carrier for another filter medium for example textile. The surface profile can be:

1. reversed triangular

2. round

3. diamond shaped

In case of round wire the support tubes can be welded with 1, 2 or 3 wires next to each other.

Advantages

Compared with conventional support elements ( such as perforated tubes, wire mesh, ....) , support elements have following advantages:

1. 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.

2. a strong mechanical construction

3. large open area

4. 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°.
