  • Publication number: 20150041412
    Abstract: A Polyionic Molecular Diffuser and Filter Method. The device and method provides superlative filtration in macro, micro and nano ranges for a variety of fluids. The device utilizes filtration elements that are relatively low cost, yet provide the significant advantage of being able to be back-flushed periodically to remove captured solids. The device employs an arrangement of filter elements wherein the filtration axis of the filters is perpendicular to the flow axis of the collecting housing. The device and method further provides a way for adjusting filter to capture different sizes of solids, depending upon the particular user adjustment. This same filter is adaptable to operate as a gas diffuser that will diffuse gas into a liquid in a very controllable manner, while also purifying the diffused air.

  • Publication number: 20150033688
    Abstract: A filter element (10) of a filter for fluid, in particular fuel, oil, water, urea solution or air, in particular of an internal combustion engine, in particular of a motor vehicle, and a method for producing the same are described. The filter element (10) comprises a filter medium (14), which is designed as a filter medium hollow body (12) and is circumferentially closed at least with respect to an imaginary axis (16). On at least one end face, the filter medium (14) comprises an end body (20). The end body (20) comprises a closing section (28), which is sealingly connected at least to the filter medium (14). Moreover, the end body (20) has a central fluid opening (24) into which a tube-like connecting element (38) of the filter can be inserted. At least one sealing section (30) is provided on the end body (20) for circumferentially sealing the fluid opening (24) with respect to the tube-like connecting element (38).

  • Patent number: 8945282
    Abstract: A versatile compact air precleaner, air cleaning method and disposable air filter cartridge for air precleaner for separating heavier-than-air particulate debris from debris laden air to provide a clean airflow, wherein a flow path for air passing through a separator chamber of the air precleaner is retroflexed en route to the outlet. A plurality of independently rotatably adjustable housing sections of a housing provide utility with multiple clean air outlet configurations, freedom of direction of ejection of particulate debris from the ejector ports, different inlet configurations, mounting of the precleaner from different sides, accommodation of different sizes of filters, and different clean airflow rate capabilities. A separator chamber end section including the ejector ports is connected to the filter as a removable, disposable air filter cartridge to obviate ejector port clogging with change of filters.
