3P Patronen Filter

Rainwater filter or underground tank filter for roof areas up to 200m^2.

For installation within rainwater tanks. Due to the inclined angle of the filter sieve and its very smooth surface structure the dirt is rinsed into the sewer. Low maintenance. Filter cartridge mesh in stainless steel within plastic housing. Mesh size of filter cartridge 0.55 mm. This product can be fitted after initial tank installation if required. The small height difference of 66 mm between rainwater inlet and wastewater outlet increases water capture.

1. Rainwater flows into the filter cartridge.
2. The filter cartridge cleans the rainwater; filtered water is led into the rainwater tank. 
3. Due to the inclined angle of the filter sieve and its very smooth surface structure the leaves and other rubbish are rinsed into the sewer.

To fit this filter to standard 4 inch pipe you need a flexible rubber 4 inch coupler at each end of the filter (available from a builders' merchant) as shown in the image. The image shows a similar cartridge filter to the one offered but the connections are the same.
To fit the filter to a 2inch or other pipe diameter you need a pipe reducer with rubber grommet to size, also from a builders' merchant.
