This is the Graf (Garantia) Regendieb (Rain thief) Self cleaning circular downpipe filter which showcases simple and innovative German design.
This represents a step change in rainwater harvesting diverters since the diverter filters leaves and other contaminants whilst capturing the majority of rainwater. This principle is shown in image 2.
The housing top (image 4) has an easy cut lid with precut grooves which can be cut to standard pipe dimensions (square and circular).
- Highest water-quality - reliably filters leaves and moss out of the rainwater
- Slef-cleaning downpipe filter with stainless steel fine filter
- Fills the rainwater tank and prevents full rainwater storage tank from overflowing
- Can be easily switched from summer to winter use by turning over the filter insert
- Downpipe sizes 7-10 cm
- High water yield (approx. 90%)
- inlet seal DN 19/32 suitable for all above ground tanks
- roof area 80 m²
The standard kit includes an outlet reducer and tank connection grommet.
For a higher flow capacity outlet consider the Freeflush high flow diverter - tank linking kit to maximise the potential of the diverter.
