A frameless EMC air filter for a conductive enclosure includes a body comprising a conductive layer disposed between two filtering layers, the air filtering layers forming a periphery of the body. The frameless EMC air filter further includes one or more bare edge portions that extend outwardly past the periphery of the body. Each bare edge portion is formed by an extension of the conductive layer capable of providing direct electrical contact with the conductive enclosure.

An arc flash management system including a cabinet having multiple walls surrounding electrical equipment capable of producing arc flash, at least one aperture within one of the walls, and an arc exhaust attachment emanating from at least one of the apertures for directing possible arc flash away from the cabinet.

According to one embodiment, a humidity control filter used in a magnetic recording/reproducing apparatus includes a housing that houses a magnetic recording medium and disposed inside the housing and close to a vent connecting the inside of the housing and outside air. The humidity control filter including a water-repellency coating having ventilation, a first adsorption layer of a porous solid having characteristics of type III isotherm according to IUPAC classification, and a second adsorption layer of a porous solid having characteristics represented by type I adsorption isotherm according to the IUPAC classification, which are provided in order from the vent.

The technology disclosed herein relates to filter assemblies and methods of making filter assemblies. One filter assembly has a first sheet of filter media having a first perimeter region and a second sheet of filter media having a second perimeter region. The first perimeter region and the second perimeter region are bonded in a rim region. A plurality of adsorbent beads are disposed between the first sheet of filter media and the second sheet of filter media, and a substantial portion of the plurality of adsorbent beads are unbonded. Other embodiments are also described.

A filter assembly has a housing. The housing has an inner body and an outer body surrounding at least a portion of the inner body. The inner body has a base extending in a lateral direction and a first sidewall extending axially outward from the base. The inner body defines a cavity. The first sidewall defines a perimetric surface around the cavity. A first filter media extends across the perimetric surface and across the cavity. An adsorbent is disposed in the cavity. The outer body has a second sidewall laterally outward from and surrounding the first sidewall. The second sidewall spans at least 50% of the axial length of the first sidewall. The outer body has a first axial end and a second axial end and a retainer portion extending laterally inward from the first axial end. The retainer portion is positioned axially outward from the first filter media.

An electronic display or monitor having an integral air purifier. The display is configured to rest on a desk and is configured so that purified air is directed toward the head of a user, enabling the user to breathe a higher percentage of purified air versus unpurified ambient air. Additional functions are included to provide enhanced functionality in a use environment, such as on a desk.

According to one embodiment, a humidity control filter used in a magnetic recording/reproducing apparatus includes a housing that houses a magnetic recording medium and disposed inside the housing and close to a vent connecting the inside of the housing and outside air. The humidity control filter including a water-repellency coating having ventilation, a first adsorption layer of a porous solid having characteristics of type III isotherm according to IUPAC classification, and a second adsorption layer of a porous solid having characteristics represented by type I adsorption isotherm according to the IUPAC classification, which are provided in order from the vent.

A multifunction display stand configured to support a display, the display stand can include a display mount assembly configured to mount to and support a display, a hub assembly comprising a recess configured to receive a modular unit positioned therein, the modular unit comprising one of: a lighting unit, a mobile power supply unit, an air purifier unit, and a speaker unit, and a legs or other type of support assembly. The modular units can be selectively installed within the recess to provide additional functionality for the display stand as desired.

A thin-film filter includes thin-film part having a film surface and a rear film surface arranged at the rear side of the film surface, a plurality of through holes, being formed to penetrate the thin-film part from the film surface to the rear film surface, the through holes are formed along by a slanting direction being made an acute angle or an obtuse angle with the film surface, and stripes-formed inner wall surfaces. The stripes-formed inner wall surfaces include stripe-like parts formed along by the slanting direction. The stripes-formed inner wall surfaces are formed inside the respective through holes.

Disclosed is a storage-type modular data center. The storage-type modular data center includes a box, a dust removing module, an evaporative cooling module, and an air supply module. The box is provided with an air inlet and an air outlet. A server is disposed between the air inlet and the air outlet. The dust removing module is disposed between the server and the air inlet. The evaporative cooling module is disposed between the server and the air inlet, and includes an evaporative media and a water sprinkling tray module. One end of the evaporative media is immersed in liquid contained in the water sprinkling tray module. The air supply module is operative to drive air to flow between the air inlet and the air outlet.
