Downpipe filters and rainwater collectors are installed directly in the downpipe, where they separate the rainwater from the dirt load.
Downpipe Filter for Rainwater
Made of stainless steel
Roof areas up to 150 m² or 1,615 sq.ft.
(temperate climate zone)
OVERVIEW
FILTER COLLECTOR FS FOR THE DOWNPIPE
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.
USAGE OF THE FILTER COLLECTOR FS
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.
FILTERING CAPACITY OF FILTER COLLECTOR FS
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.
