Pre-Tank filter

3P Attenuation and Infiltration filter with telescopic extension

Operating principle

  1. Rainwater is led onto the filter cartridge.
  2. The dirt is detained in the dirt collecting basket. The basket has to be cleaned if necessary.
  3. One inlet DN 100 can also be used as an emergency overflow.
  4. Cleaned water flows over the inlet DN 100 into the rainwater tank.

Filter for installation in the ground before the rainwater tank.

This specialised filter retains all debris in a stainless steel basket (mesh size 0,55 mm) such that no dirt is washed away into the soakaway or infiltration structure.

This filter is very suitable for equipments where the water is used in washing machines, toilet flushing and garden watering, and for sites in which the rainwater has to be drained off. That means where no connection with a sewer is possible.

All inlets and outlets at DN 100, one inlet can also be used as an emergency overflow. The cleaned rainwater is led through the lower connection into the rainwater tank. Also a calmed inlet can be installed there.

Connection capacity for roof areas up to 200 m².

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

The filter has to be cleaned depending on the contamination several times during the year
