摘要:
The invention relates to a filter apparatus (10) for cleaning functional fluids, especially selected from phosphate esters, phosphate ester-based oils, mineral oils and phenols, comprising a filter housing (12) into which a filter bed (14) has been introduced, especially consisting of a mixture of anionic and cationic ion exchange resin, and comprising at least one filter element (16) which, designed as a flow guide device, enables the diversion of the fluid from a radial to an axial flow direction (18) or vice versa.
摘要:
The invention concerns a filter element for fluids, in particular for hydraulic fluid, consisting of at least one foldable filter casing (10) with at least one filter layer (18, 20, 22, 24), which extends between two end caps (26, 32), characterized in that, in order to vary in regions the thickness of the filter casing (10), the height (h 1 ) of each filter fold (12, 44) increases from one end cap (26) to the other end cap (32) or, with the filter fold height (h 1 ) being maintained, the outer diameter (40) of the filter casing (10) varies in the direction of one of the end caps (26, 32).
摘要:
The invention relates to a filter device comprising at least one filter element, said filter element having an inner fluid space (4), and comprising a permanent magnet device with at least one rod-like body (13) that can be brought into a functional position, in which it is located at least in part inside the fluid space (4), and can be moved out of the functional position, the device being characterized in that a stripping device is provided, with at least one stripping element (29, 31) which, while the respective body (13) is being moved out of the functional position, comes into contact with the exterior thereof in order to strip off accumulated foreign matter.
