Wisy

All WISY filter inserts are designed for very low maintenance. It is virtually impossible for debris or dirt to stick to their smooth, stainless-steel surface. As a result, the filter inserts have a long service life. Since the filter insert of both versions of the filter collector is always above ground level, it is easily accessible and protected against backflow in the sewer system. The filter insert is easily accessible, when necessary it can be removed from the housing in just a few simple steps for cleaning by a high-pressure cleaner or in the dishwasher.

As with all WISY filters, the cross-sectional area for rainwater flow does not change at any point inside the filter, i.e. to ensure the free flow of water, the cross section is not restricted at any point. There is no risk of blockage even during torrential rainfall events which may flush large quantities of debris into the filter. Even a tennis ball could fall unobstructed through the filter. The hydraulic efficiency of the filter is excellent. In average rainfall, over 90% of the run-off rainwater will be filtered and collected.
