A docking station for a dust collection box comprising: a housing; a socket formed by the housing configured to receive a dust collection box of a dust extractor; first and second apertures formed through a wall of the housing which aligns with air outlet and inlet apertures of a dust collection box when the dust collection box is mounted within the socket; a connector connectable to a vacuum source; and a dust channel mounted inside of the housing, which provides a passageway between the second aperture and the connector. The docking station may further include an air vent formed through a wall of the housing to allow air surrounding the housing to enter a cavity formed inside of the housing, where the first aperture is connected to the cavity in the housing to allow air in the cavity to exit the housing through the first aperture.

The invention discloses a reticle storage device including a top lid, a bottom lid and a soft contact member. The top lid has a ceiling and a cover surrounding the ceiling. The bottom lid has a carrier and a peripheral structure surrounding the carrier. The soft contact member is configured to laterally extend in between the cover and the peripheral structure when the top lid and the bottom lid engage with each other, and to extend from an inside to an outside of the device in order to buffer the contact among the two lids.

An air-processing apparatus is provided that may include a case having an outlet formed therein, at least one louver rotatably disposed in the case to adjust a direction of air flowing through the outlet, and an output device including a lamp, a printed circuit board on which the lamp is mounted, and a transparent panel configured to allow light emitted from the lamp to pass therethrough. The at least one louver may include a plurality of vanes spaced apart from each other in a radial direction about a louver rotational shaft. The transparent panel may be disposed in at least one of the plurality of vanes.

An air-conditioning system is provided that may include a first air-processing apparatus, which includes a first inlet formed in a first surface thereof that extends perpendicular to a floor or a ceiling and a first outlet formed in a second surface thereof perpendicular to the first inlet and induces air introduced into the first inlet to exchange heat with refrigerant and to be discharged through the first outlet, and a second air-processing apparatus, which includes a second outlet formed therein so as to be open in a same direction as the first outlet and a second inlet formed therein so as to be open in a same direction as the first inlet. The air-conditioning system may be driven in a combined operation mode in which the first and second air-processing apparatuses operate simultaneously or an independent operation mode in which one of the first air-processing apparatus or the second air-processing apparatus operates.

A vacuum cleaner includes an air inlet, a filter, a fan, and a main air outlet. The filter has a clean side and an unclean side. An unclean air chamber is formed between the air inlet and the unclean side of the filter. A first air chamber is formed between the clean side of the filter and the fan. An air outlet chamber is formed between the fan and the main air outlet. The upstream end of the air outlet chamber is connected to the first air chamber. An airflow may enter the vacuum cleaner from an external environment via the air inlet under the action of the fan, and sequentially passes through the unclean air chamber, the filter, the first air chamber and the air outlet chamber the main air outlet. The vacuum cleaner may include a self-cleaning air passage and an air supply air passage.

A filter element may include first and second pairs of opposing walls extending along a longitudinal axis of the filter element. The first and second pairs of opposing walls may create a flow passage between an inlet end and an outlet end of the filter element. The filter element may further include filter media configured to separate particulates from air flowing through the flow passage, and a wedge element associated with an exterior surface of at least one of the first pair of opposing walls. The wedge element may be configured to cooperate with an interior surface of a filter housing configured to receive the filter element. Outlet edges of the opposing walls of the first pair of opposing walls may extend at a first oblique angle with respect to the longitudinal axis, and the wedge element may extend at a second oblique angle with respect to the longitudinal axis.

A filter apparatus for filtering a stream of gas. The cartridge has an upper part and a lower part. The upper part is joined to the lower part by a connection. The filter cartridge supports a filter element. The filter cartridge has a resilient connection arrangement for connecting the filter cartridge to a bowl of a filter apparatus. The filter apparatus has a head, a bowl connectable to and sealable relative to said head, and the filter cartridge.

The filtration device enables the separation and collection of dust and particles produced by the pads of a brake assembly. A first separation unit having an air filtration medium, typically annular, is provided in the housing of the device, in order to define an upstream zone where air is admitted, for example tangentially, and a downstream zone in communication with an outlet of the housing for discharging the purified air. The upstream zone is in communication with a lower stage situated lower down, in which a second separation unit is located in order to separate water from particles that have fallen from the upstream zone. A filtration by the second unit is intended to collect clean water and possibly to discharge this water by gravitational flow. The fallen particles remain trapped inside the device, under the first unit.

A compressor system includes a compression module having an inlet for receiving air; and a filter housing in fluid communication with the compression module. The filter housing is constructed to house a filter, the filter having a sealing feature disposed at a first end of the filter and having an engagement feature disposed at a second end of the filter opposite the first end. The filter housing includes a trap door constructed to contact the engagement feature, and constructed to drive the engagement feature in a direction parallel to an axis of the filter toward the sealing feature and urge the sealing feature into sealing engagement with the filter housing.

A clothes dryer has a front support and a filter apparatus. The front support includes a drying air duct having an air outlet that communicates with a circulation air duct arranged inside the clothes dryer. An air inlet of the drying air duct communicates with a clothes treating chamber of the clothes dryer. The filter apparatus is inserted into and mounted in the air duct from the air inlet and covers the whole cross section of the drying air duct. The entire filter apparatus can be accommodated and mounted in the internal space of the front support, so that the area of the filter apparatus blocking thread scraps is increased, and the filtering efficiency is improved.
