The VF1 has a high level of filtering efficiency due to its two step cleaning step, independent of flow rate. \u003c\/p\u003e\n\u003cp\u003eDue to the steep inclination of the filter cartridge the dirt is continuously cleaned away into the sewer.\u003c\/p\u003e\n\u003cp\u003eThe VF1 is frost resistant and self cleaning – which mean there is little maintenance work needed.\u003c\/p\u003e\n\u003cp\u003eTo maintain: filter insert are easily removed for cleaning and does not have to be changed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cem\u003eOptional dirt retention basket can be supplied.\u003c\/em\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eConnection capacity for roof areas up to 450 m².\u003c\/p\u003e\n\u003cp\u003eHeight difference between inlet and outlet is just 300 mm.\u003c\/p\u003e\n\u003cp\u003eThe cleaned water can be used in washing machines, toilet flushing and garden watering, in homes, in commerce, in public buildings and in industry.\u003c\/p\u003e\n\u003cp\u003eThe filter has to be cleaned depending on the contamination 1 – 2 times during the year.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHow it Works\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e1.

The pre filtered water then flows over the secondary filter sieve (mesh size 0.65 mm).

Commercial Rainwater Harvesting Filter - 2 stage - 110mm VF1 - 450m2

£289.00
Maximum quantity available reached.

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 step, independent of flow rate. 

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

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

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.
