Abstract

A filtration device (1) has a housing (4) and a filter module (2) with hollow fibers (32) surrounded by an outer shell (5). The hollow fiber bundle (6) is sealed to the outer shell (5) at each end by an adhesive (11) transverse to the longitudinal direction (10). Each end of the hollow fibers (32) is unclosed. An unfiltered product chamber (20) is between the outer shell (5) and a wall (19) of the filter housing (4) and a filtered product chamber (13) is inside the filter module (2). The bottom end of the filter module (2) connects with an intermediate section (3) that connects with a receptacle (17) of a bottom portion (15) of the filter housing (4). The intermediate section (3) forms a connection chamber (26) facing the hollow fiber ends (29) and radial feed channels (28) connect the connection chamber (26) with the unfiltered product chamber (20).
