A distributor/collector assembly (10) is composed of a screen cylinder (18), a perforated tube (13) provided in the screen cylinder and support discs (17) also provided in the screen cylinder. The screen cylinder is made of cylindrically arranged support rods (11) and a wire (12) wound helically on the support rods. The perforated tube is formed with apertures for distributing or collecting fluid which flows through the wire screen. The support discs support, on one hand, the screen cylinder on the outer peripheries thereof and, on the other, the perforated tube in the opening formed in the support discs in such a manner that space is defined between the tube and the screen cylinder. The distributor/collector assembly can be buried in catalyst in a catalyst reactor and used as a distributor or collector. The assembly may comprise more than one screen cylinder, or two perforated tubes. <IMAGE>
