A device for reducing pressure fluctuation of a pressure filter frame and a pressure filter. The device includes a pressure filter frame that is a cylindrical housing. An inner wall of the pressure filter frame is further provided with a buffer plate. A plurality of openings are provided in the buffer plate. A gap is remained between the buffer plate and the inner wall of the pressure filter frame. A plurality of supporting posts are disposed in the gap, which fixedly connect the inner wall of the pressure filter frame with the buffer plate.

A liner for a filter sub-assembly has a wall having an innermost surface that bounds a cavity extending between opposing first and second ends of the liner. The wall has a deflected portion extending into the cavity and delimiting an opening. The liner may be used in a rotor of a filter assembly.

A rotary vessel for a filter assembly has a rotor body rotatable about an axis of rotation and a spigot with a non-circular cross-section and integral with or coupled to the rotor body. The spigot extends away from the rotor body along the axis of rotation and engages with a bearing. The spigot facilitates transfer of rotary motion between the rotor body and the bearing. A filter assembly has a housing with a main body and a closure member separably attachable to the main body. The rotary vessel is disposed inside the housing. The closure member retains the rotary vessel inside the housing and is separable from the main body to permit removal of the rotary vessel from the housing. The spigot integral with or coupled to the rotor vessel engages with a bearing of the filter assembly to rotatably support the rotary vessel in the housing.

At least one infrared element arrangement having at least one infrared element (3) comprising a plurality of infrared radiators (4) is mounted on a frame moveable with respect to a synthetic filter fabric mounted to a filtering surface. The frame may have wheels or the like such that the infrared radiators may be moved along the length of the filtering surface to heat the synthetic filter fabric (6) to a temperature of 100 to 160° C. for shrinking the fabric (6) on the filtering surface (5).
