The Pre-filter Maxi is installed underground and is used for the mechanical cleaning of the rainwater inflow into rainwater harvesting systems, seepage plants and ponds.
The rainwater to be filtered flows through one or several inflows into a filter basket with a mesh width of 0.9 mm to remove debris. The filtered rainwater leaves the filter through the outflow.
The width of the mesh assures very fine filtering preventing dirt particles from entering the plants or ponds. The maximum connectable surface area is approximately 350 m².
