3P Filter Towers are suitable for connectable roof areas up to 9,000 m². Be sure to select the appropriate size for your system.
The 3P filter tower is used to clean the rainwater from roof surfaces so that it can then be collected in a cistern, allowed to seep away or discharged into a receiving watercourse. The filter tower, which is arranged in the middle of a prefabricated concrete shaft, is equipped with a stainless steel screen mesh. With a mesh size of 0.39 x 0.98 mm, particulate pollutants can be safely removed from the rainwater. T2's have two screens, T4's have four, and T6's have six screens.
The rainwater is thus purified and available for further use. The dimensions of the inlet and outlet pipes as well as the screening area are measured according to the size of the connected area.
Advantages:
·Connectable roof areas from 500 m² to 9,000 m²
·max. flow rate up to 270 l/s
·High filtration and retention of pollutants
·Compact system with high operational reliability
Function:
The rainwater running into the concrete shaft is accumulated up to the height of the base of the filter wall. It then flows evenly through the rectangular the rectangular filter surface from one side to the other. The cleaned rainwater flows out on the opposite side via the drain. The volume between the base of the column wall and the concrete wall of the surrounding shaft serves as a sludge and sand chamber.
