A duct opening portion structure includes an air intake duct; a filter that is disposed in an opening portion at an air introduction side of the air intake duct; and a bezel that is disposed in the opening portion at the air introduction side of the air intake duct, the bezel being configured to support the filter. The bezel is attached to a vehicle body-side member, and the bezel includes a rib including a support portion configured to support the filter. The filter is attached to the support portion. The rib is provided with an extension portion having a length that allows the extension portion to be directly or indirectly pressed against a seal member provided at an edge of the opening portion in a state where the bezel is attached to the vehicle body-side member.

A dishwasher includes a filter member that is inserted through the lower surface of a tub at a time of replacing the filter member and is applicable regardless of the type of a dishwasher, thereby reducing manufacturing costs and enhancing user convenience. The cylinder-shaped filter member is accommodated entirely in a filter housing, and external air flows into the filter member through the upper end and the lower end of the filter member respectively and then passes through the outer circumferential surface of the filter member, to be filtered, thereby preventing the filter member from being blocked partially and ensuring a sufficient flow rate of air.

A dishwasher includes a filter member having a handle integrally provided at an upper cover of the filter member. The filter member is accommodated in a filter accommodation space of a filter housing, where a movement space of the filter member is larger than the filter member, thereby preventing damage to the filter material or a fall of contaminants into the filter housing effectively, during withdrawal and insertion of the filter member. A separation space defined between the filter housing and the upper cover of the filter member is closed by a gasket, in the state where the filter member is disposed in the filter housing completely, thereby preventing the flow of non-filtered air into the filter housing effectively.

A dust collector apparatus includes a housing, an airflow generation module and a filter. The housing has one side formed at least one intake vent-hole and another side formed of at least one exhaust vent-hole. An inner side of the housing has an airflow channel formed between the intake vent-hole and the exhaust vent-hole. The airflow generation module comprises an airflow drawing unit for drawing an airflow in order to form the airflow channel between the intake vent-hole and the exhaust vent-hole, a control module for controlling the airflow drawing unit, and a power module. The filter is detachably arranged at the intake end and used for filtering dust in the air sucked by the airflow drawing unit. The dust collector apparatus of the present invention allows the dust particles to be properly collected by the filter without secondary scattering, and guides the airflow to be exhausted smoothly.

A gas turbine air intake system uses a filter element having a seal member with radial projections and radial recesses. The seal member forms a seal with components on the tube sheet of the system and at the end opposite of the tube sheet. At the end opposite of the tube sheet, there can be an assembly cover, or alternatively, an additional filter cartridge.

A filter support for a filter is adjustable to modify the size and/or shape of the filter. The filter support may include one or more wedges engaging a wall of the filter, and a connector connecting the one or more wedges to one another. The connector allows selective adjustment of the filter support.

A humidifier/dehumidifier device is disclosed herein. The humidifier and dehumidifier both, respectively, evaporate water from and condense water into a shared (same) water storage container. The device is fitted with an air intake and at least one air outtake. In embodiments of the technology, one or more of the air intakes receives air from outdoors. One or both of an indoor and/or the outdoor intake is used to receive air based on a determination that an indoor and outdoor humidity and temperature is most efficient to achieve a desired indoor humidity or temperature.

The disclosure relates to a sealing arrangement comprising a gasket arranged to seal a gap formed between a first element and a second element, wherein the gasket is arranged to be located in the gap and to be in contact with the first and the second elements, where the gasket comprises two elongated gasket members located on a distance from each other so as to form an intermediate gasket space confined by the gasket members and said first and second elements, and in that the sealing arrangement further comprises a pressure source adapted to apply a pressure on the intermediate gasket space, said pressure source preferably being configured to maintain a set pressure difference towards the surroundings. The disclosure further relates to a method, a system, a computer program product arranged to perform the method, a further sealing arrangement and a further method of monitoring sealing integrity of a pharmaceutical production space.

An apparatus and method are provided for an air filter configured to be mounted onto an air inlet of an internal combustion engine. The air filter comprises a first end cap configured to couple with a base which is configured to support a conventional air filter and provide an interface between the conventional air filter and the air inlet. A filter medium which is relatively thicker than the conventional air filter is configured to remove particulate matter and other contaminates from an incoming airstream. A second end cap is configured to couple with a cover which is configured to fasten the conventional air filter and the base onto the air inlet, such that the incoming airstream is directed through the filter medium. The air filter is configured to be installed in place of the conventional air filter without necessitating alteration of the base and cover.

A combination air filter and goggles includes a pair of goggles; an air filter; a tube having a first end attached to the goggles and a second end attached to the air filter; a first strap having two ends attached to the air filter; and a check valve disposed on the goggles. The air filter includes a centrifugal fan, a circuit board, a UV lamp, a filter element, a power supply, a housing, and a cover. Clean air produced by the air filter may flow to inside of the goggles.
