Efficient filter for rainwater
Function and application area
The Vortex fine filter 300 is installed underground in the horizontal water pipe. It filters the rainwater flowing in from the side and also directs it to the side of the cistern. The filter insert is made of fine stainless steel mesh with a mesh size of only 0.38 mm. This ensures that leaves, moss and other debris are separated and flushed into the receiving water.
Housing with full or reduced height
The Vortex fine filter 300 is available in two different heights. The smaller version provides a height reduction of 145 mm between inlet and outlet. At the same time, the efficiency remains almost the same at low and medium rain volumes.
The clean rainwater is optimally prepared for storage in the cistern and subsequent use in the washing machine, toilet flush, or for cleaning purposes. It is ideal for use in equestrian and sports facilities where large areas need to be watered or where there is a high demand for soft water for cleaning purposes.
All WISY vortex fine filters are also ideal for cleaning process water. Examples of applications already exist in the paper, textile, and food industries. You can also find out more about our industrial stainless steel filters.
Extremely high drainage capacity
Up to 80 liters of water per second can flow through the WFF 300. In Germany, this corresponds to the drainage volume from a projected roof area of 3,000 m².
As in all WISY filters, the open cross-section is maintained throughout. There are no constrictions in the cross-section where rainwater can accumulate. Not even in cases of heavy rainfall with high loads. Safe drainage according to DIN EN 12056 / EN 752 is always guaranteed; DIN 1989 is fulfilled.
Truck drivable or sealed
The Vortex fine filter 300 with steel lid is so solidly constructed that it can be driven over by 60-ton trucks (standard vehicles according to DIN1072 / SLW60). Alternatively, a sealed plastic lid is available for indoor use.
