FIBALON - Backwash-Grid

For large drainage holes (from a diameter of about 40 mm) or in the case that the distance from the filter housing to the drain funnel is large, we recommend you an installation of our Rückspülgitter. Individual tabs (A) from the Rückspülgitter can removed individually. The FIBALON® – Backwash-Grid can simply insert into the funnel opening or can be attached to the tube. If it is necessary you can secure the Rückspülgitter with a cable tie. For the best fitting of the whole vent tube, please remove all segments (B) of the FIBALON® – Backwash-Grid.
