As water arrives the level builds up and is equally distributed across the cascade.
Pre cleaning through the cascades. Largest dirt particles are led across the primary filter cascades directly to the sewer.
Pre filtered water then flows over the secondary filter sieve (mesh size 0,65 mm). Due to the special mesh structure of the sieve, any dirt washes directly into the sewer which means the filter is self cleaning, with very low maintenance.
Cleaned water flows to the tank.
Dirt goes to the sewer.
Rainwater filter with plastic shaft extension tube for direct installation in the ground before the tank, with locking lid.
This extension permits an easy adaptation to the height proportions at the moment of the installation on site. If necessary, the telescopic extension can also be shortened. It is also possible to use several extensions.
Two step cleaning system, therefore high level of filtering efficiency, independent of flow rate.
Due to the steep inclination of the filter cartridge the dirt is continuously cleaned away into the sewer.
Connection capacity according to DIN 1986 for roof areas up to 350 m².
Max. Flow Rate Sieve insert 1,5 l/sec = 5,4 m³ cleaned water per hour.
Height difference between inlet and outlet just 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.
