The Wisy cyclone filter is designed for rainwater filtration and is placed underground. Connected to a horizontal supply line, the rainwater is filtered and fed to the cistern. The vortex motion moves rainwater over the vertical stainless steel cylindrical filter element. Centrifugal force sucks the rainwater through the filter meshes. Dirt particles larger than 0.18 mm are diverted with the residual water to the drainage system with a filtering efficiency of 90%.
Housing made of polypropylene; filter insert in inox 1.4301 and mesh size 0.18 mm.
