  • Patent number: 6645379
    Abstract: A filter element with a cylindrical structure having a filter medium 11 mounted to a support element 10. The filter medium 11 is fastened to the support element 10 in such a way that no relative movement between these components is possible. This creates a heavy-duty assembly between filter medium and support element and increases filter life. It is thus possible for the filter to withstand a pulsating load, e.g., caused by backwashing of the filter medium, without risk of destroying the sensitive filter medium due to vibrations or any relative movement between the support element and the filter medium. This assembly may be produced by mounting the filter medium under tension to the support element and by fixing it with a reinforcement strip 12. The use of valves with switching times of less than 0.4 seconds makes it possible to achieve extremely short backwash pulses to clean the filter without risk of failure of the filter medium.

  • Patent number: 5723051
    Abstract: A gap filter for liquids of gases which has a filter body 13 which encloses a clean space within a filter housing and separates it from a dirt space. The filter body 13 is supported by an element which is constructed as a safety filter 14.

  • Patent number: 5554284
    Abstract: A backwashable fluid filter formed with a filter element which is disposed so that it can be rotated about its axis inside the filter housing by a drive mechanism and through which a radial flow passes. A backwashing device is provided which includes a dirt removal channel which extends parallel to the axis of the filter element. When the filter element is backwashed, clean fluid flows back through the filter element, removes dirt particles adhering to the filter element and carries them into the dirt removal channel. In order to pre-clean the filter element, a resiliently mounted stripping device is arranged in front of the backwashing device to remove coarse dirt from the surface of the filter element before it reaches the backwashing device. The filter element is provided with slit-like openings, each of which has a substantially U-shaped configuration and defines a resilient tongue.
