Function and field of application

The WFF 150 vortex fine filter is usually installed below ground level in the horizontal water pipe. It filters the rainwater flowing in from the side and directs it laterally to the cistern. Its filter insert consists of fine stainless steel mesh with a mesh size of only 0.28 mm. This reliably separates leaves, moss and other washed-in debris and also flushes them laterally into the receiving water. A coarser mesh size of 0.44 mm is also available as an option, as well as free-standing installation with the wall mountings available as accessories.

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.

Drainage capacity

12.8 litres of water per second can flow through the WFF 150. In Germany, this corresponds to the drainage volume of a projected roof area of 500 m². As in all WISY filters, the open cross-section is maintained throughout. There are no constrictions in the cross-section where dirt can accumulate. Not even in the case of cloudburst-like rainfall . Safe drainage according to DIN EN 12056 / EN 752 is always guaranteed, DIN 1989 is fulfilled.

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 0.28 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 washed away.

Rotatable pipe connections and optional extension tube

The rotatable outlets for flushing water and filtered rainwater create flexibility. They can be turned horizontally in relation to each other and to the inlet and thus adapted to the installation situation.

With the optional extension tube, the inspection opening of the vortex fine filter is raised to ground level.

Filter carries vehicles

The cover and housing of the WFF 150 vortex fine filter are so sturdily constructed that trucks weighing up to 30 tonnes overall weight can drive over them (standard vehicles according to DIN1072 / SLW30).

Oxygen enrichment

During filtration in the vortex fine filter, the water is enriched with oxygen. The high oxygen content additionally improves the water quality and keeps the water fresh.

Low-maintenance and -friendly

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