The wafer processing system includes a rotatable wafer support member for supporting a wafer and a plurality of collections trays disposed about a peripheral edge of the wafer support member. The collection trays are arranged in a stacked configuration, each collection tray having an inner wall portion and an outer wall portion that converge to define a trough section for collecting fluid. The system includes a chamber exhaust outlet that is formed in the housing for venting gas from the interior of the housing outside of the collection trays and a chemical exhaust outlet that is formed in the housing for venting gas that flows through the collection chamber to the chemical exhaust outlet. The chemical exhaust outlet is fluidly isolated from the chamber exhaust outlet.

A smoke evacuation system for an open surgical site is disclosed which includes a filter cartridge assembly including a housing having an inlet port, a flow path extending from the inlet port, and a filter element disposed within the flow path, a flexible conduit having a proximal end connected to the inlet port of the filter assembly, and a smoke evacuator configured for detachable connection to a distal end of the flexible conduit for drawing smoke away from the surgical site and into the filter assembly through the conduit.

Provided are an air permeable vent filter, and a headlight assembly comprising the same. The air permeable vent filter has a body in which a nanofiber web, which comprises a plurality of pores and is formed by accumulating a nanofiber electrospun from a spinning solution in which a polymer material and a solvent are mixed, is spirally wound, and the air permeable vent filter implements an air permeable filter function of allowing air to pass through from one lateral side of the body to the other lateral side and blocking liquids and solids.

A range hood for collecting oil scattered from a rotating disk filter, capable of improving the cleaning workability is provided. The range hood includes a fan configured to generate an air flow, a disk filter provided on a flow path of the air flow and having a slit, a motor configured to rotate the disk filter, a rectifying plate provided upstream of the disk filter on the flow path of the air flow, and a disk cover configured to surround an outer periphery portion of the disc filter and having an outlet portion that allows oil from the disk filter to flow out to a predetermined portion of the rectifying plate.

A filtration system for a ventilation hood includes a first filter and a second filter, operatively disposed in series. The first filter is configured to be mounted within the ventilation hood, and has an air inlet, an air outlet, and a grease outlet. The second filter includes a filter material with an upstream surface and a downstream surface, an upstream housing element abutting the upstream surface of the filter material, and a downstream housing element abutting the downstream surface of the filter material. The housing elements include openings, and hold the filter material in compression.

A sterilization cabinet for use in an autoclave. The sterilization cabinet includes one or more filtered vents permitting sterilization agent to enter and exit the interior space of the cabinet during a sterilization cycle. Each vent is occluded by a cover plate. The cover plate contains a latch configured to accept a rod extending from the center of the vent and engage a notch disposed thereon. The floor of the cabinet is shaped to direct the liquid contained within the cabinet to flow into the drain port disposed within the floor. The drain assembly is used to expel the liquid from the cabinet while preventing microbes and contaminants from entering the cabinet. The hinges connecting the door to the cabinet can be used to adjust an angle of inclination, a horizontal position, and a vertical position of the door.

The present disclosure relates to air filters. More particularly, it relates to air filters including pleated filter media that can be uniformly expanded and contracted. In some embodiments, the air filters are adjustably sized air filter systems. In some embodiments, the air filters can be used in a window opening.

A foldable display device is provided. The foldable display device includes a flexible display module, a bottom frame, middle frames, and a connecting member. Two ends of the connecting member are provided with filter components. An accommodating cavity is formed among the flexible display module, the middle frames and the bottom frame communicating with an external environment through the filter components, so as to prevent the dust generated by the friction of components of the connecting member and the dust entering the accommodating cavity from the external environment, thereby avoiding short circuits and display malfunction of the foldable display device.

Some embodiments of the invention include a filter for a waste tank, the filter including a housing with a pair of end fittings; an inner tube positioned within the housing, the inner tube having perforated walls; and a negatively charged resin positioned between the housing and the inner tube. The first end fitting may be configured to attach to the tank's vent line, and the second end fitting may be configured to attach to external venting tubes such that fumes from the waste tank are configured to flow from the waste tank, through the inner tube of the filter, and away from the waste tank.

The electronic cabinet for enclosing electronic components generally has a housing having a base and a cover being connected to one another a plurality of lateral walls, one of the plurality of lateral walls having a first opening; a lateral perforated plate being mounted to the housing and extending over the first opening, the lateral perforated plate having a plurality of perforations; and a protector plate being mounted to the housing and extending over the lateral perforated plate to cover the plurality of perforations of the lateral perforated plate, the protector plate defining at least one air inlet between the protector plate and the lateral perforated plate.
