Example:
The 3P Hydrosystem 1000 traffic installed in
a concrete shaft DN1000. The cleaned storm
water is then discharged into an infiltration
system using plastic crates.

Buoyancy restraint for filter elements
The HS1000 is available with various filter types, depending on the usage of the connected area. The Roof type is used for roof areas that do not have a
significant proportion of uncoated metals; the Metal type is employed for metal roof areas, and the Traffic type is used for slightly polluted traffic areas.
The Heavy Traffic type is employed for heavily polluted traffic areas and has been granted general technical approval
(
Z-84.2-4) by the German Institute for Structural Engineering (DIBt). The maximum areas that may be drained depend on the nature of the surfaces.
These are given in the following table.
