De400 PRO branched chamber

PRO400 Sewer Chamber with Branch Base

The concept of PRO chambers is based on improved hydraulic performance and controlled structural strength.
All PRO chambers feature very deep and smooth flow channels. Direction changes inside the chamber are made with the maximum possible radius.
The flow channels are free of sharp corners, steps, and joints that could obstruct proper wastewater flow.
All PRO chamber bases can be installed at depths of up to 6 meters (with groundwater levels as shallow as 1 meter below the surface).
The strength of the chamber bases and riser pipes always complies with the requirements of standard EVS-EN 13598-2:2009.
Chambers have injection-molded bases with channels according to EN 13598-2

• The connection between the chamber base and riser pipe is sealed with a gasket
• Equipped with NAL-type inlet and outlet connections
