Wisy Vortex Fine Filters |
The unique construction of the vertically placed fine filter washes out debris and fine dirt. Moss, leaves and insects are automatically washed into the drain. Absolutely safe function with over 90% of the rainwater collected. Cleaner rainwater for household use. All connect to the drainpipe in the ground. Meets DIN 1986. Extension pipe (500 mm) is included.
Area of application:
The effectiveness of the WFF is dependent upon various influences (quantity of rainfall, roof size and pitch, coefficient of discharge etc.). An approximate value for use could be:
WFF100:
Filters up to 2,000 sq.ft. Includes housing, extension tube, upper ring, filter insert, lifting handle and housing lid. Connects to standard storm water pipes below ground. A 50 cm extension tube can be used to raise the inspection opening to ground level. Housing of polypropylene, filter insert of stainless-steel, dishwasher safe. Filter mesh (basic version).
WFF150:
Filters up to 5,500 sq.ft. Includes housing, extension tube, upper ring, filter insert, lifting handle and housing lid. Connects to standard storm water pipes below ground. A 50 cm extension tube can be used to raise the inspection opening to ground level. Housing of polypropylene, filter insert of stainless-steel, dishwasher safe. Filter mesh (basic version).
WFF300:
Filters up to 33,000 sq.ft. For installation below ground. Housing of polypropylene, filter insert of stainless-steel, filter mesh size 0.38 mm. The unit consists of a housing, final/closing or intermediate ring with certificated child safety, steel cover, filter insert, base plate and 50 cm stainless-steel lifting handle.
The WFF, that is connected to a horizontal drain, filters the rainwater from the roof which is then led to a cistern. The rainwater coming from the roof runs into the side of the WFF and is widely spread over the cylinder-shaped filter mesh. The rainwater from the roof is drawn through the vertically placed fine filter there, by exploiting the natural adhesion forces (surface tension), and is led through the outlet to the storage cistern, while the dirt is washed into the drain with the remaining water. Over 90% of the rainwater entering the WFF is filtered by this principle. The full cross-section of the rainwater drainages system remains continuously open in the WFF.
There are no reductions in the cross-section of this appliance in which dirt and water can collect. This is especially important with torrential rainfalls where large quantities of water enter. In such cases over 50% of the filtered water is still led to the storage cistern. Excess rainwater is led directly into the drain. The filter mesh largely cleans itself because practically nothing can remain on the vertical mesh.
Pitched roofs of slate, clay or concrete tiles are most suitable for collecting rainwater. Planted roof areas are less suitable because of the low water-collection efficiency. Non-sealed asbestos cement roofs are unsuitable. They not only cause environmental and health problems but their fibers tend to block the fine filter mesh. With the help of the blind insert the collection and filtering of the appliance can be stopped. The rainwater from the roof then flows directly into the drain (stopping the rainwater system, winter operation).
The WFF100 equipment:
Housing of polypropylene, filter of stainless-steel, rainwater inlet, cistern inlet, drain connection, cistern and drain connections are fixed on opposite sides. The rainwater inlet can be turned 360 degrees.
The WFF150 equipment:
Housing of polypropylene, filter of stainless-steel, rainwater inlet, cistern inlet, drain connection. All pipe connections can be turned 360 degrees.
The Vortex Fine Filter WFF 300 filters rainwater from large roof areas and are ideal for industrial and public buildings harvesting up to a maximum of 16 litres per second. Also used for mechanical cleaning of processing water for reuse the WFF 300 built of such stable construction, trucks can drive over it.
The Vortex Fine Filter (WFF 300) is connected to the DN 300 drain pipe. It filters the rainwater coming from the roof vertically through the adhesion cylinder according to the unique WISY principle. The inspection opening can be raised to ground level for deeper installations with the extension piece. Easily fitted on site, permanently stable and safe in operation !
