    • There is disclosed an actuator (55) for a separator (5) for separating contaminants from a fluid stream which includes entrained contaminants. The actuator is arranged to move along an actuator axis (56) to adjust an open cross-sectional area of at least one aperture (29) of the separator through which the fluid stream flows, and comprises a flexible diaphragm (31) for occluding the at least one aperture, and a support assembly (33) for the flexible diaphragm. The support assembly is movable along the actuator axis carrying the flexible diaphragm and has a lower support member (58) and an upper support member (60) mounted on the lower support member so that a portion of the flexible diaphragm is located between the upper and lower support members. The lower support member comprises a radially extending support portion (62) and an axially extending support portion (64) coupled to the radially extending support portion. The upper support member comprises a radially extending support portion (66) and a diaphragm anti-inversion feature (68) coupled to the radially extending support portion. The diaphragm anti-inversion feature extends in an axial direction so that it axially overlaps at least part of the axially extending support portion of the lower support member.
