The filter collector for the downpipe

The FS filter collector filters the rainwater directly in the downpipe while it is still being drained off to the side of the cistern.

Its filter insert consists of fine stainless steel mesh with a mesh size of only 0.28 mm. This reliably separates leaves, moss and other washed-in debris and flushes them downwards into the receiving water.

Use of the filter collector FS

Use of the filter collector FS

The filter collector FS filters the rainwater from up to 150 m² of roof surface (projected onto the plane). Then it is optimally prepared for storage in the rainwater storage tank and can be used in the garden, the toilet or the washing machine. The materials stainless steel or copper are available for visual matching to the downpipe.

Capacity of the filter collector FS

The flow through the filter collector can be up to 4.2 l/s, corresponding to the capacity of the downpipe.

As in all WISY filters, the open cross-section is maintained throughout. There are no constrictions where rainwater can accumulate. Not even in the case of cloudburst-like rainfall with heavy dirt input.

Safe drainage according to DIN EN 12056 / EN 752 is always guaranteed, DIN 1989 is fulfilled.

At the same time, the filter has a high hydraulic efficiency. As soon as the filter fabric is wetted with water, at an inflow of one litre per second, about 0.98 litres per second are filtered and directed to the rainwater storage tank.

Low-maintenance and -friendly

All WISY filter inserts are designed to be particularly low-maintenance. Their smooth stainless steel surface makes it almost impossible for impurities to adhere.

As the filter insert is above floor level, it is easily accessible and protected against backwater in the sewer system. If necessary, it can be removed from the housing in a few easy steps and cleaned with a high-pressure cleaner or in a dishwasher.
