摘要

The module (100) has plain and edge ribs (1-4) forming a square shaped mesh. The mesh is held with a plate shaped diffusion wall (5) in a wall zone. The ribs are made of plastic material such as polycarbonate material. The wall is connected to the ribs. The ribs and the wall are formed of a single part by molding. The wall is provided with pores which widen from one surface of the wall to another surface of the wall alone an angle of 15 degrees. An independent claim is also included for a method for manufacturing a fluid diffusion wall forming module.
