All connections DN 110.

Height difference of 117 mm between rainwater inlet and wastewater outlet.

Mesh size of filter cartridge 0,7 x 1,7 mm.

The cleaned water can be used in washing machines, toilet flushing and garden watering, in homes, in commerce, in public buildings and in industry.

How it works

  1. Rainwater is led onto the first filtration step.
  2. Coarse and larger dirt particles are led away to the sewer.
  3. The pre-filtered rainwater, having passed the primary filter, reaches the second and finer filter. From here finer dirt passes to waste, clean water to the tank.
  4. The cleaned rainwater is led through a calmed flow inlet into the rainwater tank.
  5. Due to the steep inclination of the fine filter and its smooth surface structure the dirt is quickly cleaned away into the sewer.
