Rainwater filter for roof areas up to 3,500 square feet. Provides a high level of filtering efficiency, independent of flow rate. Continuous filtering of dirt particles. Frost resistant. Self cleaning. Low maintenance intervals Filter insert is easily removed for cleaning. Materials: PE and stainless steel. Stainless steel sieve with a mesh size of 0.021"/0.55mm. Height: 18.5"/470mm. Height difference between inlet and outlet just 11.8"/300 mm.

1: As rainwater arrives, the water level builds up until it overtops the filter lip, providing equal distribution across the full width of the filter cascade. 2: Larger debris is removed by the filter cascade and washed downstream with a small amount of rainwater. 3: Pre-filtered water falls through the filter cascade and flows over a secondary filter sieve (mesh size 0.021"/0.55mm) removing the finer particles. Due to the special structure of the sieve mesh, any dirt is washed directly downstream making the filter self cleaning, with minimal maintenance required. 4: Cleaned water flows to the rainwater storage tank. 5: Dirty water flows downstream.
