Rainwater filter for larger roof areas. The 3P volume filter VF2 must be in- stalled in a pre-shaft (Ø 1000 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 manhole. The dirt falls to the bottom of the shaft and is flushed away during heavy rain.

• By means of a bypass installation, a larger connection area is possible
• Rainwater inlet: DN 200
• Inlet rainwater storage tank: DN 150
• Drainage sewer: DN 200
• Height difference between inlet and outlet: 320 mm
• Mesh size: 0.39 x 0.98 mm
