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 the
stormwater.
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 into the
stormwater. Very low maintenance.
Installation advice 3P Volume Filter combi:
• Connections to the 3P Volume Filter VF1 combi can be made with universal connectors.
• Rainwater enters through the upper inlets, at DN 100. For roof areas up to 175 m²
connect from either right or left.
• For roof areas above 175 m² we recommend you connect from both sides, in order to obtain
the maximum filter efficiency.
• Saw off 1 cm from the outside of the selected inlet(s).
• Cleaned water is led via the outlet at DN 125 to the storage tank.
• Dirty water goes via the outlet at DN 125 to waste.
4. Cleaned water flows to storage
5. Dirt goes to the stormwater
