A filter device for fluids has a filter housing (1), in which element receptacles (31) for a plurality of filter elements (33) are provided. The filter medium (35) of the filter elements (33) separates in the filter housing (1) a dirt side (5) from a clean side (7). The filter housing (1) can be opened for inserting and removing the filter elements (33). For the filter elements (33), a support basket (19) is provided, which can be inserted into the filter housing (1) and removed from the filter housing (1) and to which the filter elements (33) can be detachably fixed. The filter elements (33) have, in addition to the filter medium (35) for particle filtration, an adsorption medium (36).

Proposed is a moisture removal device using a rotating disk and nitrogen peeling according to the present disclosure may include a circulation pump unit for circulating the oil in the storage tank connected to the circulation pump on one side of the device body via a valve, a chamber for exposing the oil circulated through the circulation pump unit into the chamber headspace through the rotation of the plurality of rotating disks, and a membrane unit that supplies dry nitrogen gas to oil exposed in the chamber headspace through rotation of a plurality of rotating disks of the chamber. The moisture removal device may remove free moisture, emulsified moisture, and dissolved moisture in oil contaminated with moisture through dry nitrogen gas purging by using a continuously rotating disk.

Systems and methods for managing debris material in a fluid are described. In examples, the system may include a flow line that directs a fluid into an inlet of a barrel, through the barrel to filter at least some material from the fluid, and out of an outlet of the barrel. The system may also include a backflush line coupled to the flow line between an inlet valve and an inlet of the barrel and between an outlet valve and an outlet of the barrel. In examples, the system includes a pump positioned on the backflush line, where in a backflush mode, the inlet and outlet valves close to isolate the barrel, and the pump circulates the fluid through the backflush line and through the barrel in a reverse direction to move fluid and material from the barrel to a screen overflow assembly.

A filter device for filtering a fluid may include a flat filter element. The flat filer element may extend flat in a longitudinal direction and a transverse direction. The filter element may include at least one pleated filter medium through which a flow path of the fluid leads in a height direction. The at least one filter medium may include a top side and a bottom side facing away from the top side. At least one strainer may be arranged on the top side. The at least one strainer may extend flat parallel to the filter medium and may include a strainer material having multiple passages such that the flow path leads through the strainer in the height direction.
