Volume Filter – VF1 Combi

VF1 Combi in-tank water filter

VF1 Combi Filter


Rainwater filter for installation inside or on the tank. The VF1 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 VF1 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.

Same functionality as 3P Volume Filter VF1 (a pre-tank filter).

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.

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. As water arrives the level builds up and is equally distributed across the cascade.
  2. Pre cleaning through the cascades. Largest dirt particles are led across the primary filter cascades directly to waste.
  3. 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 to waste which means the filter is self cleaning, with very low maintenance.
  4. Cleaned water flows to the cistern through the outlet at the bottom of the filter.
  5. Dirt goes to waste.
