Overview

Operating principle and applications

The filter collector is installed in the vertical rainwater downpipe. It filters the runoff rainwater from the roof before discharging the filtered water through the outlet connection to the storage tank. Its filter insert is made of a fine stainless-steel mesh with a mesh size of only 0.28 mm. Leaves, moss and other debris entrained in the rainwater are reliably filtered out and flushed away through the downpipe to the soakaway or drain.

Rainwater cleansed by this filter is in a perfect condition for tank storage and for subsequent use in the washing machine or for flushing toilets and general household cleaning.

Filtering capacity

The maximum flow rate through the filter collector is 4.2 litres per second (depending on the capacity of the downpipe). 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. The filter collector meets the requirements defined by EN 12056 / EN 752 and also conforms to DIN 1989. The hydraulic efficiency of the filter is excellent. With an inflow rate of 2 litres per second, for example, 90 % of the inflowing water is harvested as filtered water.

Filter Collector FS for the downpipe

The Filter Collector FS can be fitted anywhere in the downpipe. To install the filter collector, a section measuring 32 cm must be cut out of the downpipe and replaced by the filter collector. A projected roof area of 150 m² (1615 sq.ft.) can by drained by this version of the collector. The housing is available in stainless steel or copper so that it can be visually harmonised with the existing downpipe.

Easy to maintain — low-maintenance design

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.

The filter insert is easily accessible and protected against backflow in the sewer system. When necessary, the insert can be removed from the housing in just a few simple steps for cleaning by a high-pressure cleaner or in the dishwasher.
