Regenwasserfilter LineAr 100 K von WISY


Minimum Height Differential, Straight Piping

Whether for new builds or retrofits: The space-saving LineAr 100 rainwater filter is easy to plan and can be installed without any extra excavation work. There are just five centimeters height difference between the rainwater inlet and the dirty water outlet. Thanks to this minimal height difference, the LineAr 100 rainwater filter is extremely easy to integrate into existing pipework. It can even be placed directly inside a rainwater storage tank without changing the gradient of existing piping.

Sophisticated design

WISY‘s LineAr 100 Rainwater Filter has a vertical filter mesh. Leaves, moss and other suspended particles are simply flushed past the filter into the drain outlet. This is the crucial advantage of this design over filter surfaces that are almost horizontal and become clogged with dirt very quickly. These are commonly found in other products. The pipe diameter is uniform throughout the LineAr 100 Rainwater Filter. Even a tennis ball washed off the roof by rain can pass unhindered through the filter housing.

The harvested rainwater is not only clean, but naturally soft as well. It is of an ideal quality for flushing toilets, washing or irrigating the garden.
