A modular filter element that has a first elongate hollow body and a second elongate hollow, where a female portion extends axially into a wall of one of the elongate hollow bodies and a male portion extends axially from the other elongate hollow body into the female portion to connect the first elongate hollow body to the second elongate hollow body is disclosed.

A droplet coalescing filter cartridge is provided. The filter cartridge includes an outer filter tube and an inner filter tube disposed within the outer filter tube, and is configured to provide parallel filtration of a fluid flow. The filter includes a depth media configured to coalesce fine droplets or aerosols from an air flow. The filter cartridge is suitable for use in a coalescing filter assembly including the filter cartridge and a secondary filter element.

An air filter group for air supply to internal combustion engines of motor vehicles, of a type comprising an external casing provided with an inlet opening of the air to be filtered, and an outlet opening of the filtered air, and a removable cover, the inlet and outlet openings being separated by a removable filter cartridge which comprises a hollow cylindrical filter wall crossed by the air in a centripetal direction, in which the at least a filter cartridge is fixed to the cover in which cover a chamber is present, delimited by a base provided with at least a hole at which the at least a cartridge is fixed, by an opposite wall to the base and by an annular wall located between the base and the opposite wall and comprising the outlet hole of the filtered air, the cover being destined to be inserted sealedly in the casing.

A catalytic filter with enhanced catalyst carrying capability comprising high temperature resistant inorganic fibers, at least one binder and at least one high surface area catalyst support material. Also, a method for making the catalytic filter having at least one high surface area catalyst support material.

A filter candle is provided, comprising one or more filter elements shaped as hollow cylinders of porous material, the filter elements having substantially identical inner and outer diameters and are disposed coaxially with each other; a support element comprising a metal tube disposed within the filter element(s), said metal tube having an outer diameter smaller than the inner diameter of the filter element(s), said metal tube having a wall with a plurality of perforations; and at least two annular sealing disks having an outer diameter equal to or larger than that of the filter element(s) and an inner diameter smaller than that of the filter element(s), wherein first and second terminal sealing disks are disposed at opposite axial end faces of a single filter element or of a plurality of filter elements disposed in line,
wherein the filter elements are compressed between the first and second terminal sealing disks.

A sealing element (5) for a filter element (2) in a housing body (1) of a filtration system, preferably in a cross-flow filtration system. The sealing element (5) is one piece and is annular in shape and comprises one section for sealingly arranging the filter element (2) in the housing body (1) and one section for impact damping for the filter element (2)

A filter cartridge has a filter medium that is provided at least on an end face with a flange that serves for the installation of the filter cartridge in a filter arrangement, whereby the flange has a radial flange and a support section, whereby the support section extends in the lengthwise direction of the filter cartridge.

A dust filtering and collection system for filtering dust and other particles from an air stream generally being used for conveying granular material into or from a bulk tank, with the filtering system designed to incorporate structure, such as a specially designed grommet, for holding a porous filter tube for filtering out such dust particles, with a grommet having structure to provide for its interlocking and engagement with and through an aperture in a transverse plate within the system. The grommet has an upper flange, that engages the upper surface of the transverse plate, and has an inner flange for engagement with the upper edge of the filter tube, while the bottom of the grommet has resilient fingers and associated detents for engaging the bottom of the transverse plate, to furnish an interlocking of the grommet, with its supported filter tube, onto and through the transverse plate.

Filter element (1), in particular filter cartridge, for filtering exhaust gases or process gases, having a filter body (2) which defines a longitudinal direction (R) and is subdivided along the latter into a plurality of substantially tubular filter body elements (7, 8) which are each connected in pairs at their end portions (9, 10) pointing towards one another, wherein the filter body (2) defines an interior space (5) of the filter element (1), wherein two filter body elements (7, 8) connected together in pairs are screwed together by means of internal and external threads (11, 12) formed at their end portions (9, 10) and corresponding to one another and are additionally glued together in their contact regions by means of an adhesive (13).

A high-temperature high-efficiency explosion-proof integrated modular dust removal equipment for pyrolysis raw coal gas, including: a housing internally provided with a chamber, the chamber being enabled a medium to flow from a gas inlet to a gas outlet of the housing; a high-temperature ceramic filter system for dividing the chamber into a dust collection chamber and a gas purification chamber that are individual, and being located in the dust collection chamber to communicate the dust collection chamber and the gas purification chamber; a high-pressure backblow system located in the gas purification chamber and used for performing blowback operation towards the dust collection chamber; and a preliminary dust removal system positioned outside the housing and communicated with the dust collection chamber.
