Installation and function

The WFF 100 vortex fine filter is usually installed in the ground in front of the cistern in the horizontal rainwater pipe. However, it is also suitable for free-standing installation, in which case it is best fixed with the optionally available wall fastening.

Rainwater flowing in from the side is filtered by the WFF 100 vortex fine filter and passed on to the cistern. In the process, it passes through the filter insert made of fine stainless steel mesh with a mesh size of only 0.28 mm. In this way, not only leaves and moss, but also smaller particles washed along with the water are reliably separated and flushed into the canal or an infiltration trough.

Made in Germany

Rain from
200 m² roof surface

This is how much water the WFF 100 can filter.




Ideal for the family house

The WFF 100 rainwater filter is perfectly suitable for your detached family house. It collects water for the garden, flushing the toilet or the washing machine.

Efficient rainwater filter

Convince yourself of the high performance of the WISY vortex fine filters: The rainwater flowing in from the side is efficiently filtered by the filter insert made of fine stainless steel mesh with a mesh size of only 0.28 mm and passed on to the cistern.

In this way, leaves, moss and smaller particles washed along with the water are reliably separated, permanently washed down the filter mesh.

Reinigung

Low maintenance

The filter insert keeps itself clean and rarely needs cleaning.



Easy cleaning in the dishwasher

When the time comes, cleaning is particularly easy. For example, in a standard dishwasher.

Drainage-proof according to standard!

The open cross-section of the rainwater pipes (DN 110) is maintained throughout the entire filter. There are therefore no constrictions where first dirt and leaves and later rainwater could accumulate. Not even in the case of cloudburst-like rain.

Further advantages of the WFF 100 vortex fine filter

Oxygen enrichment

During filtration in the vortex fine filter, the water is enriched with oxygen. The high oxygen content additionally improves the water quality and prevents the growth of undesirable, anaerobic microorganisms.

Cover and housing accessible by truck

The cover and housing of the WFF 100 vortex fine filter are designed so sturdily that they can be driven over by lorries weighing up to 30 tonnes (standard vehicles according to DIN1072 / SLW30).

5 years warranty

In the unlikely event of a material defect, WISY provides a five-year guarantee.

Made in Germany

Storable

The filtered rainwater can be stored long-term in a cistern without further treatment.

WISY guarantee - valid for 5 years

All components of the vortex fine filter are subjected to thorough quality control to ensure perfect operation. In the unlikely event of a material defect, WISY offers a five-year guarantee.
