Prefilter Maxi Plus

2. Function
The rainwater flows through the inflow (A) into the filter case, then through the meshes into the
filter cartridge (B, mesh width 0.5 mm) and the cleaned water flows out through the outflow (C)
into the tank.
Particles of a certain size, which are heavier than the water, settle in the filter case (D). This
settling process is improved by the retention time and design of the filter cartridge.
Settling of particles lighter than water is improved by the filter meshes in which only small
particles or droplets, with accordingly few impetus, stick. Other incoming small particles or
droplets form bit by bit by the bigger impetus which rises (coalescence effect).
Because of the design of the filter case – remobilisation, the large entry pipe and the mesh width
of the filter (size of maximum 0.5 mm)- heavy rainfall will not impair the quality of filtered water.
