Rainwater filter for larger roof areas. The 3P volume filter VF3 must be in- stalled in a pre-shaft (Ø 1200 mm). As a rule, standard concrete manholes are used. The filter can be delivered to the construction site pre-assembled in the shaft.
Due to its 2-stage cleaning principle (first coarse, then fine cleaning), it has a high degree of efficiency independent of the volume flow. Due to the steep position of the filter insert, the filtered-out dirt is continuously flushed in the direction of the sewer, with the sewer connection being attached to the man- hole. The dirt falls to the bottom of the shaft and is flushed away during heavy rain.
