  • Patent number: 11065941
    Abstract: A vehicle intake air filter is provided forming an inner conduit formed between an upper orifice and a lower orifice. In addition to an outer filtering layer, a secondary filtering layer or layers are provided spanning the upper orifice. A monitoring mechanism for measuring and communicating a function of the air filter is further located within the upper orifice. The monitoring mechanism measures and communicates the function of the air filter. A plurality of sensors measure a differential pressure between the outer and inner surfaces of the filter. A remote communication system transmits sensor data from the sensors via a wireless communication protocol to a remote electronic monitor device, such as a cell phone. Increased pressure differential or filter performance or efficacy may thereby be displayed to the user on a real-time basis. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

The fiber bed can be made very thin while retaining high efficiency in removing small particles of aerosol from a gas stream passing through the fiber bed. The fiber bed collecting media strip lends itself to be applied to the mist eliminator by spirally wrapping the element onto the mist eliminator. The fiber bed collecting media strip can overlap itself to seal at the locations where the fiber element overlaps itself. The fiber bed collecting media strip can be provided to the field in different formats for use in making a mist eliminator fiber bed.

  • Patent number: 7425227
    Abstract: A pleated fluid filter element for removing particulate matter from a fluid stream that comprises a pleated filter media provided with a plurality of pleats having peaks and valleys and having a clean and dirty side. The pleated filter media further has arrays of elongated embossments projecting from both the clean and dirty sides thereof. The arrays of the elongated embossments are positioned so that the elongated embossments embossed on adjacent pleats of the filter media are offset from each other in a direction parallel to the peaks and valleys. The elongated embossments are provided for maintaining gaps between the pleats and spaces within the pleats and for channeling fluid into and out of the filter media.

  • Patent number: 7416576
    Abstract: A fiber bed assembly for a mist eliminator that operates at high efficiency and inhibits re-entrained liquid from leaving the mist eliminator. The fiber bed assembly has a construction that facilitates rapid drainage of liquid collected by the fiber bed. A pre-filter media can be employed upstream of the primary collection media to remove larger liquid drops. The pre-filter media can be used in unique combination with other features to reduce liquid re-entrainment, and/or allow increased flow capacity.

  • Patent number: 6953124
    Abstract: A filter element for end face inlet formed of triangular channels which are alternately closed such that the fluid to be filtered must pass through the filter material in order to flow from the inlet side (22) to the discharge side (23). The channels are formed by alternating flat layers (17) and folded layers (18), whereby all sides of the inlet channels face a discharge channel. A particularly high filter efficiency is thereby achieved such that a large filter surface area and a high filter capacity are attained with a relatively small structural volume. The filter can be used, for example, as an air filter for various air filtration applications.
