A filter module (10) is within the housing (44) and communicates with the inlet (45) and the outlet (43) such that fluid passing to the inlet (45) is filtered by the filter module (10) before passing to the outlet (43)

A filter assembly comprises a housing (44) with an inlet (45) and an outlet (43). A filter module (10) is within the housing (44) and communicates with the inlet (45) and the outlet (43) such that fluid passing to the inlet (45) is filtered by the filter module (10) before passing to the outlet (43). The filter module (10) includes a filter membrane (11) of hollow cylindrical shape having an air throughput of at least 1300 normal cum/hr per 250 mm of the axial length of the membrane at an inlet pressure of 2 barg. Such a filter module (10) can be used in a process system (40) in which the module (10) supplies sterile air and is testable in situ.
