The Filter Collector FS filters runoff rainwater from the roof just before discharging it 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.
The Filter Collector FS filters rainwater from up to 150 m² (1,600 sq.ft.) of roof area (projected onto the plane, in temperate climate zones).
Rainwater cleansed by this rainwater filter is in a perfect condition for tank storage and for subsequent use in the garden, for flushing toilets or for the washing machine.
The housing is available in stainless steel or copper so that it can be visually harmonised with the existing downpipe.
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. As soon as the filter mesh is wetted with water, around 0.98 out of one litre per second are filtered and fed to the rainwater storage tank.
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.
