3P Inox Attenuation Flow Regulator

Flow regulators slow the outflow during to rain events to protect the sewer or a surface water from excessive inflows.

Device for installation in the retention tank. The 3P Inox attenuation flow regulator ensures a regular, predefined outflow. The flow rate is adjustable (5 levels). The movable arm and brushes attached to the regulator ensure that the regulator opening does not become dirty and thus requires little maintenance.

Compared to a conventional static outflow regulator, the outflow from the 3P Inox attenuation flow regulator adapts to the current water level in the retention facility, so that the maximum permissible outflow is already reached at the beginning of the reservoir filling. With conventional regular elements, the maximum permissible discharge is usually only reached at the highest water level in the retention facility; at lower water levels, the throttle capacity decreases accordingly. Thus, when using the 3P retention throttle Inox, the required retention volume can be reduced by approx. 30 %.

The 3P retention throttle Inox also has the advantage over a static throttle that blockage or clogging of the outlet opening cannot occur. Depending on the water level, the sickle-shaped orifice plate in front of the opening is moved so that any impurities that may be present are permanently sheared off with the help of a pair of brushes. This ensures that decentralized retention of private properties is guaranteed in the long term without any maintenance effort.
