  • Filter device
    Patent number: 8741016
    Abstract: A filter device has a compact filter made of a filter material that is wound spirally. A star filter that is made of a filter material that has folds arranged in a star shape surrounds the compact filter. The filter device has a cylindrical shape. A fluid to be filtered passes the compact filter in an axial direction and the star filter in a radial direction. The filter device is exchangeable and is mounted in a filter housing such that the compact filter and the star filter have a common raw side and a common clean side that are separated from each other.

  • Integral filters for separating fluid components and housing for them
    Patent number: 4909937
    Abstract: In an integral filter (F) for separating fluid components which filter can be enclosed in a surrounding housing (1,2) with fluid connections (A1 l to A3, 10) the permeable tube jacket of which filter consists of several tubular filter elements (K1, K2) with different filter qualities whose cross sections are stepped in such a manner that a smaller filter element is surrounded by a larger filter element, optionally with formation of an intermediary space (Z1), and in which the two tube ends are enclosed by closure and connection adapters (15, 20, 21, 22, 27, 31) and can be adapted to fluid chambers (13, 14) of the housing, sections of the total filter (F) can be selectively tested for integrity, supplied with and emptied of fluid and filling substances via an intermediary space (Z1) between two filter elements (K1, K2) which intermediary space can be separately controlled and loaded from the outside.
