The at least one hood-outlet (52) is designed for surrounding, a plurality of cell-inlets (36) of the cyclone cells (28) of the cyclone block (12). A wall (70) of the hood (40) defines a distributor volume (72) inside the hood (40), which is located between the at least one hood-inlet (50) and the at least one hood-outlet (52). The wall (70) has at least one line or area of inflection (74), where at least one inner surface of the wall (70) changes its curvature.

Embodiments disclosed herein may provide an air conditioner having a case and a cover coupled to the case. A cover separation unit may separate the cover from the case at upper and lower sides. The cover separation unit may include a lever that slides along an outer surface of the case and a pusher rotatably coupled to the lever to rotate to push the cover. A guide may guide the pusher to rotate as the pusher is moved along an outer surface of the case.

A method and system for manufacturing and using a self-supporting structure in processing unit for adsorption or catalytic processes. The self-supporting structure has greater than 50% by weight of the active material in the self-supporting structure to provide an open-celled structure providing access to the active material. The self-supporting structures, which may be disposed in a processing unit, may be used in swing adsorption processes and other processes to enhance the recovery of hydrocarbons.

A cylindrical filter element having a central longitudinal axis and filter media including a plurality of radially extending pleats arranged in a pattern that repeats around the central longitudinal axis. Each of the pleats comprises an inner pleat tip, wherein the inner pleat tips of each pattern define an open area that extends along a height of the filter element, and wherein each pattern of pleats comprises a first series of intermediate pleats that descends in length from a major pleat to a minor pleat and a second series of intermediate pleats that ascends in length from the minor pleat to a major pleat of an adjacent pattern of pleats.

Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly includes a housing and cover within which primary and secondary filter cartridges, having a media pack and a seal arrangement surrounding the media pack, can be installed. The filter cartridges can include an open end cap with an axially deviating seal arrangement and a plurality of axially extending channels for engaging with ribs on the housing. The filter cartridges can also include extension members extending from the open end cap that include the axially extending channels, entirely or partially. The filter cartridges can also include a guide member extending from the extension members for providing a low friction surface against the housing during installation that allows axial force exerted by the installer to be translated into a rotational force that rotates the filter cartridge during installation.

An air cleaning module includes a filter, a fan, a light source unit, a housing and a guide structure. The fan is configured to provide a suction direction and a blowing direction of a fluid which are substantially aligned. The light source unit is arranged to be adjacent to the filter to emit a light toward the filter. The light having a property that sterilizes a contaminant source in a fluid. The housing includes a fluid passage space. The guide structure is arranged between the fan and the filter and configured to guide a fluid to move along a fluid passage path set by the guide structure. The filter and the light source unit are arranged in the fluid passage space such that the light source unit sterilizes a fluid as a fluid flows toward the light source unit.

The present disclosure relates to fine filter part kit (63), comprising a replacement fine filter part (15) that is adapted to be mounted to a fine filter section (12) for a dust extractor (1). The fine filter part kit (63) further comprises a filter lid (16) that is adapted to be mounted to a corresponding used fine filter part (15) to be replaced, already mounted to the fine filter section (12), and thereby seal an opening (28) of a particle containing space inside the used fine filter part (15) before removing the used fine filter part (15). In this way, release of particles contained in the particle containing space into the ambient air is prevented and a secure disposal of the used fine filter part (15) is enabled.

A gas-liquid separator includes a first cylinder body, a second cylinder body, a first flow guide portion, a second flow guide portion, a gas-liquid distribution assembly and a heat exchange assembly. The first cylinder body is located inside the second cylinder body. The gas-liquid separator has a first cavity and a second cavity. The heat exchange assembly is at least partially located in the first cavity. The heat exchange assembly includes a heat exchange tube, a first heat exchange member and a second heat exchange member. The heat exchange tube at least partially surrounds the first cylinder body. The first heat exchange member and the second heat exchange member have different structures. A thermal management system having the gas-liquid separator is also disclosed.

An air cleaner assembly is described and shown which includes a housing having an air flow inlet, an air flow outlet and a housing body and access cover. A serviceable filter cartridge is positioned within the housing. A projection/receiver arrangement providing for engagement between the cartridge and the housing is provided. The projection/receiver arrangement can be configured in a manner that inhibits undesired motion of the cartridge, once installed. An example projection/receiver arrangement is provided, which includes a serpentine receiving groove on the access cover and a serpentine projection on the filter cartridge. Example filter cartridge features are described.

The invention relates to a wall-flow filter as a particle filter with catalytically active coatings in the channels which are closed in a gas-tight manner at the opposing closed ends of the channels A at the first end, wherein the inlet region of the filter is additionally supplied with a dry powder-gas aerosol which contains metal compounds with a high melting point (such as the metal oxides Al2O3, SiO2, FeO2, TiO2, ZnO2, etc. for example) and which is to simultaneously improve the catalytic activity and the degree of filtration efficiency with respect to the exhaust gas back-pressure.
