Volume Filter – VF1

VF1 Filter


The VF1 rainwater filter can be installed within a rainwater tank or before the tank in the ground. The VF1 has a high level of filtering efficiency due to its two step cleaning process (first coarse, then fine filtering) independent of flow rate. Visit our clean water page.

Due to the steep inclination of the filter cartridge the dirt is continuously cleaned away to waste.

The VF1 is frost resistant and self cleaning – which mean there is little maintenance work needed.

Same functionality as 3P Volume Filter VF1 – Combi.

To maintain: filter insert are easily removed for cleaning and does not have to be changed.

Optional dirt retention basket can be supplied.

Connection capacity for roof areas up to 450 m².

Height difference between inlet and outlet is 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.

How it Works

1. Water enters the calming sump, and weirs over evenly onto the filter cascade.2. The large particle of debris are washed over the primary cascade, and filters out to waste.

3. The 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.

4. Cleaned water flows to storage.

5. Dirt passes to waste.
