Residential Rainwater Filter Collector

The rainwater coming from the roof through the down pipe is drawn through the vertically placed stainless steel filter insert by adhesion forces. It is then led through the outlet to the rainwater storage tank.

Because of the German patented unique construction, the dirt particles are rinsed directly into the drain with the remaining rainwater. More than 90% of the water passing through the filter collector is filtered and collected by this principle.

METHOD OF MAINTENANCE 


Filter Collector Maintenance


Minimal maintenance of the FS/GRS filter collector is required. The internal filter mesh is a vertical type of filter, therefore very little debris willow remain trapped on the mesh surface. This is enhanced further by the self cleaning properties which washes away all the remaining debris on the filter mesh with the next heavy rainfall. However, over a period time, depending on the roofing material and area of collection, a thin coating forms on the filter element. This has little effect on the water flow but it is recommended to maintain the filter twice a year to maintain the rainwater collection efficiency.

Filter Mesh Maintenance Method  


1. To take out the filter mesh. First, remove the filter collector outlet (4) pipe connection
2. Slide up the upper housing at the down pipe by approximately 10cm.
3. Lift out the filter casing (2) from the lower pipe. Take out the filter mesh and clean it using garden house, High pressure cleaner or sponge. Do not brush it with rough material as it will damage the strainer.
4. Install back to the down pipe. The unit can be use straight away after cleaning.
