The filter collector for the rainwater downpipe

The FS filter collector filters the rainwater directly in the downpipe while it is still being drained to the side of the cistern. Its filter insert is made of fine stainless steel mesh with a mesh size of just 0.28 mm. This reliably separates leaves, moss and other debris and flushes it down into the receiving water.

Use of the filter collector FS

Use of the FS filter collector

The FS filter collector filters rainwater from up to 150 m² of roof surface (projected onto the level). It is then optimally prepared for storage in the rainwater storage tank and can be used in the garden, toilet or washing machine.

Stainless steel or copper are available for visual harmonisation with 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.

Filter collector FS
Low-maintenance filter collector FS

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.

Simple installation

The FS filter collector can be installed in the downpipe easily and without much effort. A section of the downpipe is cut out according to the instructions and the filter can be inserted directly.

The FS filter collector sits precisely on the lower section of the downpipe so that no further fastening is required and installation is completed in just a few minutes. The filter collector is then immediately ready for use and ensures efficient rainwater utilisation.
