Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
A device for separating debris and other such material from rainwater as it flows into a downpipe from a roof gutter and for simultaneously preventing the ingress of mosquitos into the downpipe, said device comprising a compartment adapted to be fitted to an upper end of the downpipe, which compartment includes an upwardly facing inlet having a main screen with a mesh size of between 5 mm×5 mm and 12.5 mm×12.5 mm arranged at an angle of between 20° and 45° with respect to an imaginary horizontal line so that debris washes over the main screen for discharge outside the device, the device further comprising a secondary screen located within the compartment of smaller mesh opening than the main screen, and being closely spaced from the main screen to act as a secondary filter below the main screen, through which rainwater passes, said device including a horizontally arranged tertiary screen having a mesh opening of approximately 0.9 mm×0.9 mm located below said secondary screen in such a manner that a head of water forms over said tertiary screen and which acts as a tertiary filter for excluding the ingress of mosquitos.
