3P Volume Filter
3P Volume 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.
- The selection of the correct filter or diverter will normally depend on the size of your roof area, however for simple diversion on guttering downpipes the filter collector FS is ideal.
- On larger projects the garden filter will cope with roof areas up to 200m² and the volume filter up to 450m². Both units can installed within the top of the tank, however they are large units and general access for other components such as submersible pumps can prove tight. On this basis we would normally recommend they be installed direct buried by opting for the 'filters with extension'.
- When routing clean rainwater from the filter to the underground tank this filter should be introduced into the tank via a downpipe with a calmed inlet on the bottom, this ensures that settled debris on the bottom of the tank is not disturbed.
- An overflow to the normal drainage system or soakaway should always be in place, this ensures a continual turnover of water within the tank when at high level.
Volume Filter Spec
- Rainwater filter for roof areas up to 450m².
- Has a 2 stage filtering system, first a cascade to remove leaves and other large particles the a 0.55mm mesh sieve filter to remove small debris.
- All filter debris then passes to the sewer outlet.
- The volume filter is frost resistant and self cleaning for low maintenance.
- Made from PE and stainless steel, can be installed within the tank or below ground with extension.
- Height difference between inlet and outlet 300mm.
- Unit approx. 390mm diameter, 415mm height.
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.
