ABSTRACT:
The invention relates to performing exchanges between two fluids by means of a stack of membranes (13, 13') between which separator frames (1, 1') are interposed. According to the invention, the seal plane is obtained by assembling four thermoplastic sheets about a screen (8), with the outermost two sheets (16, 17) being flexible and hollowed-out in zones corresponding to diffusers, and with the inner two sheets (14, 15) situated on either side of the screen (8) being semi-stiff, with at least one of them not including an opening in the diffuser zone. The four sheets are assembled together without exerting pressure over the diffusers (9) such that the, or each, semi-stiff sheet forms a protective element over a diffuser zone.
