Assembly in dihedron:
In the case of important flows, the cells type 16 and KNOWN thickness 38 and 50 mm can be gone up in dihedrons. Frontal surfaces are then reduced in a ratio from 3 to 1. The cells type 16 equipping the dihedrons are provided with handles (contrary to the cells KNOWN cut-rate version).
Dihedrons MIOFILTRE are superimposed easily to constitute "plates support" or "boxes".
