The WISY Vortex Underground Filter is designed to handle water from a number of rainwater downpipes. Installed underground it becomes an integral part of the rainwater drainage system, meeting all the requirements of the German DIN (Land and Drainage) 1986. The standard size is suitable for roof areas of up to 500 m², the small size for roof areas up to 200m². The self-cleaning filter captures over 90% of the rainwater, filtering it and diverting it into a storage tank. The remaining water carries leaves and any other debris from the roof and gutter straight into the drain or soak away. The filter can be easily removed for maintenance purposes. |
The simple but high precision WISY filter uses surface tension in conjunction with a fine stainless steel filter mesh to exclude most particles. The filtered rainwater is therefore very low in organic matter and can be stored for many months, if necessary, with no deterioration in water quality.
The Vortex Underground Filter is installed underground to handle the water from a number of downpipes, becoming an integral part of the rainwater drainage system. It meets all the requirements of DIN 1986.
The Vortex comes with a 500 mm extension piece to suit invert levels found on most site conditions. Extra extension pieces can be ordered separately if necessary. The filter housing and extension piece are made from environmentally compatible polypropylene and can take the weight of a 12 tonne truck (i.e a direct loading of 3 tonnes).
Since their invention in Germany in 1989, WISY filters have been successfully installed in over 100,000 homes. A rainwater harvesting system is increasingly becoming a standard feature in many new homes on the continent.
The standard Vortex has 3 separate sections. The rainwater inlet, filtered water outlet and drain outlet can be positioned at any angle to each other thus allowing total flexibility of positioning of drainage runs.
The rainwater inlet on the small Vortex can be changed to any position. The filtered water outlet and drain outlet are fixed at 180 degrees to each other.
