Powerful rainwater filter
Convince yourself by watchin the adjacent video clip 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 fabric and then transported into the canal or an infiltration.
Low maintenance and easy to clean
Like all WISY rainwater filters, the WFF vortex fine filters are extremely low-maintenance and only need to be inspected 2 times per year. If cleaning is necessary, the filter insert can be easily removed from the housing and cleaned in the dishwasher.
As the filter insert is made entirely from high-quality stainless steel, it is extremely durable. Thousands of WISY vortex fine filters have been in operation with the original filter insert for well over 20 years. The plastic housing will also last you a lifetime.

Vortex Fine Filter WFF 100
The WFF 100 vortex fine filter is usually installed in the horizontal rainwater pipe in the ground in front of the cistern. 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.
