Efficient rainwater filter

Convince yourself of the high performance of the WISY vortex fine filters: The rainwater flowing in from the side is efficiently filtered by the filter insert made of fine stainless steel mesh with a mesh size of only 0.38 mm and passed on to the cistern.

In this way, leaves, moss and smaller particles washed along with the water are reliably separated, permanently washed down the filter mesh and then transported into the canal or an infiltration trough.

Function and field of application

The vortex fine filter 300 is installed below the ground surface in the horizontal water pipe. It filters the rainwater flowing in from the side and also directs it laterally to the cistern. Its filter insert consists of fine stainless steel mesh with a mesh size of only 0.38 mm. This reliably separates leaves, moss and other washed-in debris and flushes them downwards into the receiving water.

Overview

The clean rainwater is optimally prepared for storage in the cistern and subsequent use in washing machines, flushing toilets or for cleaning purposes. The use in riding and sports facilities is ideal where large areas have to be irrigated or the demand for soft water for cleaning purposes is high.

All WISY vortex fine filters are also ideally suited for cleaning process water. Examples of applications can already be found in the paper, textile and food industries. You can also find more details on our stainless steel industrial filters.

Extremely high drainage capacity

Up to 80 litres of water per second can flow through the WFF 300. In Germany, this corresponds to the drainage volume of 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 the case of cloudburst-like rainfall with heavy load input. Safe drainage according to DIN EN 12056 / EN 752 is always guaranteed, DIN 1989 is fulfilled.

Truck accessible or sealed

The vortex fine filter 300 with steel lid is so sturdily constructed that 60-tonne lorries are allowed to drive over it (standard vehicles according to DIN1072 / SLW60). Alternatively, a sealed plastic lid is available for indoor use.

Enclosure with full or reduced height

The vortex fine filter 300 is available in two different heights. The smaller version offers a reduced height distance of 145 mm between the inlet and the outlets. At the same time, the efficiency remains almost the same for weak and medium rainfall events.

Twistable outlet spout and optional extension tube

The rainwater inlet and the outlet of the cleaned water can be freely rotated horizontally so that they can be adapted to the installation situation. The outlet of the flushing water for the dirt load is directed vertically downwards and can be diverted in any horizontal direction by means of a 90° bend. The optional extension pipe makes it possible to adjust to the surface level.

Low-maintenance and -friendly

All WISY filter inserts are designed to be particularly low-maintenance. Their smooth stainless steel surface makes it difficult for impurities to adhere. If necessary, the filter insert can be easily removed from the top of the housing with the help of the lifting bracket provided and cleaned with a high-pressure cleaner or in a dishwasher.

Oxygen enrichment

During filtration in the vortex fine filter, the water is strongly enriched with oxygen. The high oxygen content additionally improves the water quality and prevents the growth of undesirable microorganisms.
