The VF1 Combi has the cleaned water outlet at the bottom of the filter. Rainwater filter for roof areas to 450 m². High level of filtering efficiency, independent of flow rate. Continuous filtering of dirt particles. Frost resistant. Self cleaning. Low maintenance intervals Filter insert is easily removed for cleaning. Materials: PE and stainless steel. Stainless steel sieve with a mesh size of 0.55 mm. Height 470 mm. Height difference between inlet and outlet just 300 mm.

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 fitted 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.

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 the sewer.
3. Pre filtered water then flows over the secondary filter sieve (mesh size 0.55 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 the cistern.
5. Dirt goes to the sewer.
