Wff Vortex Fine Filter 3000sqft Capacity: 40 M3/hr

The vortex fine filter WFF 100 is usually installed below ground in the horizontal rainwater pipe.
It filters the rainwater that flows in at the side of the filter unit and releases the filtered rainwater 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 to the soakaway or drain.
A filter insert with a larger mesh size of 0.44 mm is optionally available.
Wall mountings are also available as accessories to install the filter as a free-standing unit.
Rainwater cleansed by this filter is in a perfect condition for tank storage and for subsequent use in the washing machine or for flushing toilets and general household cleaning. It is also ideal for use in sports or equestrian facilities where large playing or riding surfaces need to be irrigated, or where large quantities of soft water are needed for cleaning purposes.
All WISY's vortex fine filters are perfect for filtering process water.
They are already successfully deployed in the paper, textile and food industries.
The WFF 100 is capable of filtering up to 4.2 litres per second.
This corresponds to the drainage volume for a projected roof area of 200 mA A .
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 vortex fine filter meets the requirements defined by EN 12056 / EN 752 and also conforms to DIN 1989.
