Disclosed is a disposable filter capsule apparatus that incorporates integral quick connect components and check valves to facilitate assembly to, and dis-assembly from, larger assemblies and apparatus. The quick connect elements and valves are configured to eliminate the need for auxiliary sealing elements, e.g., o-rings and valve springs so as to prevent unwanted reactions with fluids and/or gases flowing through the capsules, and to further prevent the disposal of expensive re-usable elements in the disposable capsules.

A filtration article including a composite filtration structure, a seal region positioned within the composite filtration structure, and an attachment weld that interconnects the seal region and an outer casing is provided. The composite filtration structure includes a stacked filter material including at least two fluoropolymer membranes and a support layer. The support layer may be formed of a thermoplastic or thermoset polymer. When heated, the polymer in the support layer melts and flows into the fluoropolymer membranes. In exemplary embodiments, the polymer is imbibed through the thickness of the fluoropolymer membranes. The attachment weld may be positioned at any location within the seal region so long as the attachment weld is positioned a distance from the outer periphery of the composite filtration structure. The filtration article is small in size, is lightweight, and may be used as a sterilizing grade filter. Methods of producing the filtration article also provided.

This gas purification filter unit (10) is provided with: a first elimination unit (11) that eliminates gas component impurities among the impurities contained in ozone generated from an ozone generating device; and a second elimination unit (12) that is disposed at a later stage than the first elimination unit and that further eliminates solid particulate impurities from among the impurities from which the gas component has been eliminated. Ozone containing impurities are caused to flow in from the inflow end (10a) of such a gas purification filter unit (10) and is passed through the first elimination unit (11) and second elimination unit (12), and thus ozone from which impurities have been eliminated is discharged from an outflow end (10b).

Embodiments provide a filter with a generally rectangular, non-cylindrical profile. The filter may have multiple pleat packs positioned between pleat covers that define regions and flow channels in a cavity of the filter body. The pleat covers have openings that allow a fluid to flow through the multiple pleat packs via parallel flows or series flows. End caps bonded to the body define flow passages for directing the fluid from an inlet to an outlet via the pleat packs for series or parallel filtration. The pleat packs may be made of the same or different materials and may be configured with the same or different heights based on flow requirements. A cage or a separator may be positioned between the pleat packs. The pleat packs may be made of a continuous pleated membrane with bridges defining a space between the pleat packs to accommodate the cage or separator.

The present disclosure is directed to a novel redesigned or retrofitted cabin air filtration system utilizing an ultraviolet light, radiation, or an energy matrix membrane and related technology to eliminate toxins such as viruses, bacteria, mold, fungi, rickettsia, protozoa, etc. from the air system in a vehicle, such as an automobile, marine vehicle airplane, etc., thereby improving the current cabin air filter functionality and providing a sterile air distribution environment throughout the cabin of the vehicle or small area.

A device for separating a fluid component from a fluid, in particular compressed air of a vehicle, is provided. The device has a first container for containing the fluid, the first container being arranged to separate at least a part of one or more components contained in the fluid from the fluid, and a second container, the second container being arranged to separate at least a part of one or more components contained in the fluid from the fluid. The two containers are interconnected by a throttle device adapted to throttle a transfer of at least a part of the fluid from the first container into the second container.

A device for separating a fluid component from a fluid, in particular compressed air of a vehicle, is provided. The device has a first container for containing the fluid, the first container being arranged to separate at least a part of one or more components contained in the fluid from the fluid by evaporation. The first container includes one or more openings through which a substance can be supplied to the fluid in the first container for breaking an emulsion or mixture of two or more components contained in the fluid and an exhaust through which the at least part of the one or more separated components can be exhausted.

The present invention provides a smart air filter blockage detection and alert communication system for use with filters in air circulation systems such as HVAC, vehicles, server systems, and dryers. The system attached to the frame of a filter comprises a light source, a light sensor, two actuators and a control unit. The control unit based on a stored program or an external command activates the actuators to place the source and the sensor devices attached to the two arms of the actuators on the two sides of the filter membrane. The sensor measures the light intensity transmitted through the filter. The control unit upon receiving the intensity data determines the filter blockage level and communicates alert to the user when the blockage exceeds a predetermined value. The system uses a 4G or a 5G IoT network capability for data collection and communication with servers and user devices.

The present invention provides an apparatus for removing particles using symmetrical gas injection, the apparatus comprising: a casing having an inner space; a gas injection part in which a plurality of gas nozzles are formed on one side of the casing, the plurality of gas nozzles are disposed symmetrically and away from an object, and particles on the surface of the object are removed by means of injecting gas on the object; and a recovery part which has a recovery pipe inserted therein and connected to the other side of the casing and is for recovering, via the recovery pipe, the particles which have been removed from the object. According to the present invention, the gas nozzles inject in symmetrical directions and thus diffusion of particles removed from the surface of the object is prevented, the object is not contaminated, and the particles can accurately be recovered, detected and counted.

The present invention relates to a porous sheet product, to a filter element comprising the porous sheet product, to a method for producing the porous sheet product, to a method for producing the filter element, and to the use of the sheet product and of the filter element.
