  • Patent number: 9180388
    Abstract: A filter device for fluids, in particular for low viscosity fluids such as water, includes a filter housing (1) in which element holders (31) are provided for a plurality of filter elements (21). Filter medium (35) of each filter element in the filter housing (1) separates an unfiltered side (5) from a clean side (7). The filter housing (1) can be opened for inserting and removing the filter elements (21). A carrier in the form of a basket (19) is provided for the filter elements (21). The basket can be inserted into and removed from the filter housing (1). The filter elements (21) can be releasably secured at the basket.

  • Patent number: 7883559
    Abstract: A system for gas cleaning has at least one casing (1) with a first chamber (31) into which the gas to be cleaned can be flowed and with a second chamber (33) from which the cleaned gas exits. A filter device (35) can have the gas flow through it and can be arranged between the chambers. The filter device has filter media both for the separation of solid particles and for dehumidifying the gas by separating out coalesced liquid. The system has, upstream of the filter device (35), an arrangement (11, 37) for preliminary dehumidification of the gas.

  • Patent number: 7198715
    Abstract: A device for separating fluid mixtures, in particular for separating water from oil, includes a vacuum container (10) with several sub-chambers (26, 44, 40). At least one liquid constituent of the fluid mixture can be transported from the vacuum container after separation, by a transport device (12). The other constituents can be extracted from the vacuum container (10) in the form of gas and/or steam, using a vacuum pump (20). One of the sub-chambers (26) of the vacuum container (10) houses a heating device (28, 30), which heats the fluid mixture. The fluid mixture is guided into an additional sub-chamber (40), and is separated into its constituents by traversing a packed bed. Even cold and consequently viscous fluid mixtures can be supplied, due to the heating device, for separation inside the aforementioned vacuum container.
