Bester Fallrohrfilter
für Regenwasser in Ihrer Regenwasseranlage
Noch bevor das Wasser die Regentonne oder die Zisterne erreicht, wird es im Fallrohrfilter von Laub und Schmutz befreit. Dafür wird der Regenfilter direkt ins Fallrohr eingesetzt und wird zum Vorfilter für Zisterne oder Regentonne.

Funktion und Vorteile
eines guten Fallrohrfilters
Fallrohrfilter von WISY sind mehr als ein Sieb im Fallrohr oder ein einfacher Dachrinnen-Filter. Sie sammeln sauberes Regenwasser und spülen ungewünschte Partikel direkt fort.
Downpipe filter for your rainwater system
Even before the water reaches the rain barrel or cistern, it is cleaned of leaves and dirt in the downpipe filter.
For this purpose, the downpipe filter is inserted directly into the downpipe and connected to the rainwater storage tank.
Below you will find our downpipe filters. Feel free to take a look around!

This is how the WISY downpipe filter works:
While coarse leaves, foliage or similar impurities fall down the centre of the downpipe, water follows the inner walls of the pipe. In the WISY downpipe filter, the rainwater is pulled sideways by means of adhesion force and can directly be stored in the rainwater storage tank.
The dirt continues to fall downwards and is ejected there or flushed directly into the sewer. Clogging of the downpipe filter is not possible, as the inner diameter does not narrow at any point in the filter. For dirt, the downpipe filter therefore simply behaves like a piece of pipe.
Vorteile des Fallrohrfilters
statt Regenklappe, Laubabscheider und Dachrinnen-Filter
Früher wurde zum Sammeln von Regenwasser oft eine einfache Regenklappe verwendet. Gelegentlich kamen Laubabscheider oder Dachrinnen-Filter zum Einsatz, um Schmutz aus dem Regenwasser zu entfernen. Ein Fallrohrfilter ist jedoch allen um Längen überlegen.
Why a downpipe filter is important
Without a downpipe filter, dirt particles can get into the rainwater storage tank. e.g. these could be leaves from trees, moss from the roof or dead insects. This is organic material that decomposes over time and becomes a nutrient for microorganisms.
As in a pond with too high a nutrient input, this, in combination with a lack of oxygen, may lead to unpleasant odours. Coarse contamination can also block the tap or damage a pump.
A downpipe filter protects you from all this: it removes organic substances from the rainwater before they reach the rainwater barrel or rainwater storage tank.
Downpipe filter vs. rain flap
The rain flap diverts the entire water flow with all the dirt and allows the rainwater to splash into the container until it overflows. The collected water thus contains all the dirt that has been rinsed off the roof. When the container is full, the water overflows uncontrollably and floods the surrounding area. Only when the rain flap is closed manually does the flow into the container stop. If the rain flap is forgotten to be opened again, the container will remain empty the next time it rains.
The rain flap is also usually used in combination with open collection containers or rain barrels, which have their own disadvantages and risks. Additional dirt, e.g. leaves, falls directly into the barrel, mosquito larvae swim there in summer and, in the worst case, they also pose a danger to children at play. WISY therefore recommends using closed rain barrels.
Downpipe filter vs. leaf separator
The leaf separator can divert very coarse soiling, but after a short time it also diverts a considerable portion of the water flow, as dirt gets stuck in the separator and the water can no longer flow completely towards the container. If the connected container becomes full, it then overflows uncontrollably and floods the area surrounding the container. Leaf separators can be useful if the aim is to reduce the amount of dirt entering the connected wastewater pipes. For cases in which the rainwater is not to be used.
With WISY downpipe filters the rain barrel does not overflow
If the rain barrel is full, the water is diverted downwards in the correctly installed WISY downpipe filter so that the barrel cannot overflow. With both the rainwater flap and the leaf separator, on the other hand, a full rainwater barrel would overflow because there is no hydraulic coupling of the water level between the rainwater storage tank and the downpipe filter.

Diameter of downpipe and downpipe filter
The diameter of the downpipes is determined by the planner so that rain that falls on the roof surfaces can always run off. Like the downpipes, every rainwater filter must also be sufficiently large so that it does not become an obstacle during heavy rainfall.
The applicable standard for rainwater harvesting systems defines that there must be no constriction at any point in the rainwater filter, as otherwise dirts can collect there and form a blockage. This rule also applies to downpipe filters. All WISY filters fulfil this requirement. WISY downpipe filters are suitable for all standard downpipe diameters from 76 mm to 120 mm.
To ensure that the downpipe filter fits your downpipe, WISY offers several versions of each downpipe filter for different pipe diameters. This means you will find the right model for all standard downpipes so that the downpipe filter and downpipe fit together and the filter works perfectly. By their design a blockage of your downpipe is impossible with WISY downpipe filters.
What is important when installing the downpipe filter?
In order to achieve an optimum water yield, the water coming from above should be able to flow further along the inner wall of the pipe as it enters the downpipe filter, from where it is filtered and discharged to the container. To do this, the burr created during sawing should be removed with a file.
