450m2 Combi Rainwater Filter

Rainwater filter for installation inside or on the tank. The Combi has the cleaned water outlet at the bottom of the filter. Whilst the dirt is washed away sidewards, the bottom cleaned water outlet position makes installing the filter in tanks very easily and practically. Where used before the tank, the Combi gives a high degree of flexibility to the angle of direction of the cleaned water outlet pipe, feeding to the rainwater tank. The Combi can also be fitted directly to the top surface of the rainwater tank, using a seal we can provide. This means it is acting as a second turret to the tank.

Connection capacity according to DIN 1986 for roof areas up to 450 m².

Max. Flow Rate Sieve insert 1,5 l/sec = 5,4 m³ cleaned water per hour.

The height difference between inlet and outlet 300 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.

The filter has to be cleaned depending on the contamination 1 – 2 times during the year.

How it works

  1. Water is equally distributed across the cascade
  2. Cleaning occurs through the cascades with the largest dirt particles forced across the primary filter cascades directly to the sewer
  3. Pre filtered water then flows over the secondary filter sieve (mesh size 0.65 mm), where the mesh structure washes any remaining dirt into the sewer
  4. Cleaned water flows into the tank
  5. Dirt goes directly to the sewer
