A dust cup assembly (100) and a handheld cleaner (1000) having the same are provided. The dust cup assembly (100) includes: a cup casing (1); a device housing (2) configured as a tube shape and disposed in the cup casing (1), wherein an outer end face of the device housing (2) at an axial side thereof abuts against or extends beyond a partial inner surface of the cup casing (1), and a dust removal chamber (A1) is defined between an inner surface of the cup casing (1) and an outer peripheral surface of the device housing (2) and surrounds the device housing (2) along a circumferential direction of the device housing (2); and a negative pressure device (3) located within the device housing (2) and enabling dusty air to enter the dust removal chamber (A1) for dust and air separation.

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.

Apparatuses for controlling fluid flow are important components for delivering process fluids for semiconductor fabrication. These apparatuses for controlling fluid flow require a variety of fluid flow components which are tightly packaged within the apparatuses for controlling flow. In an effort to improve packaging density, fluid delivery modules preferably incorporate both active and passive components into a single substrate block. This enables increases in packaging density as well as enabling reduced cost through greater simplification of the fluid delivery module. For instance, incorporating a filter to filter incoming fluid with a valve or other component in a single monolithic block avoids the need for separate components which add cost and complexity.

A filter system for a vacuum cleaner is disclosed. The system comprises a housing reconfigurable relative to a bin between an operative configuration in which the housing is disposed upon the bin so that dirt separated from dirt-laden air can collect in the bin, and an idle configuration in which the housing is removed from the bin. The housing comprises an inlet for receiving dirt-laden air into the housing, an outlet via which cleaned air can exit the housing. The system further comprises first filtering means and second filtering means disposed within the housing, the first filtering means being positioned upstream of the second filtering means. The first and second filtering means comprises a filter medium configured to separate dirt from the dirt-laden air passing from the inlet to the outlet through the filter medium. The system further comprises filter cleaning means for removing dirt from the filter medium of the first filtering means when the housing is configured at least in the operative configuration.

A dust collector (1) is provided with a tank section (10) and a head section (20). The tank section (10) has a dust collection chamber (13) for containing dust. The head section (20) has a motor (23) and a dust collection fan (25). The dust collection chamber (13) has a cylindrical filter device (12) which, when air sucked in from the suction opening (11) flows through the filter device (12), separates dust from the air. A passage member (50) forms an air passage by which the outside air and a filter interior space (14) inside the filter device (12) are connected without having the filter device (12) therebetween. A cover body (60) closes the passage member (50) in an openable manner. The passage member (50) has first opening sections (53) facing the filter interior space (14) and located at different positions in the circumferential direction of the filter device (12).

A hand vacuum cleaner comprises a cyclone, a conical pre-motor filter that is positioned rearward of the cyclone and a suction motor. The pre-motor filter has a front end that faces towards the cyclone air outlet. The conical pre-motor filter has an open interior volume, an outer surface, which is an upstream surface of the pre-motor filter, and an inner surface, which is a downstream surface of the pre-motor filter.

A filter element (100) that is to be mounted in a housing (102) has at least one substantially hollow cylindrical filter bellows (10, 20) designed to separate liquid from aerosol, and two cover elements (30, 40) designed to cover axial end regions (12, 14, 22, 24) of the filter bellows (10, 20). The axial end portions (12, 14, 22, 24) of the at least one filter bellows (10, 20) are pressed against the cover element (30, 40) by an axial compressing force. The at least one filter bellows (10, 20) is secured in the axial direction, and one respective sealing zone (16, 18, 26, 28) is formed between each filter (10, 20) and each cover element (30, 40).

A device for filtering a flow of cooling air for cooling a low-pressure turbine of a turbomachine, includes a duct having a geometry configured to centrifuge the flow of cooling air passing through the duct, the duct having openings dimensioned to enable a separation of the solid particles contained in the flow of cooling air being centrifuged.

A dishwasher comprises a tub that defines a wash space configured to accommodate one or more objects to be washed, a sump that is configured to store wash water, a water supply pump that supplies the wash water to the tub, a base that is disposed below the tub, and provides a space to accommodate the sump and the water supply pump, an air supply device that is configured to supply air to the tub, a first filter that is disposed at the base and in fluid communication with the tub and the air supply device, a second filter that is disposed at the base and in fluid communication with the tub, and a water supply that is connected to the second filter and configured to supply the wash water.

A system for processing a semiconductor wafer is provided. The system includes a processing tool. The system also includes gas handling housing having a gas inlet and a gas outlet. The system further includes an exhaust conduit fluidly communicating with the processing tool and the gas inlet of the gas handling housing.
