A filter cartridge for a sterilizing cabinet includes a first gasket comprising a rigid or flexible edge portion and forming a frame defining a hollow center portion, a first filter comprising a porous material for maintaining a sterilized condition in the sterilizing cabinet and passing gaseous materials through the porous material, wherein the first filter is affixed to the first gasket, and a second filter comprising a porous material for maintaining a sterilized condition in the sterilizing cabinet and passing gaseous materials through the porous material, wherein the second filter is either affixed to the first filter or the first gasket opposite the first filter, and wherein the filter cartridge provides sufficient structural integrity to form a sealing interface with a confronting surface of the sterilizing cabinet.

This publication discloses a filter unit connectable to a mobile communication device including a fan for generating an air flow inside the filter unit, electrodes covered with a photo catalytic material like TiO.sub.2 in the air flow, UV-LEDs illuminating the electrodes, and outlet for the air flow directed in direction of user of filter unit.

An object of the present invention is to provide a safety cabinet that allows a clearer observation of contamination of an operation stage surface. In order to realize the object, the safety cabinet is configured to include an operation space including an operation stage; a front panel formed in a front surface of the operation space; an operation opening provided in a lower portion of the front panel; a suction port that is provided in the vicinity of the operation opening on a front side of the operation stage to lead downward; and an air circulation path through which air suctioned from the suction port flows along a lower portion, a back surface, and an upper portion of the operation space, in which the operation stage is made of a transparent material, and a light source is provided to irradiate the operation stage with a light from a side of the operation stage, which is opposite to the operation space.

A trap bowl is provided to accumulate liquid droplets from a filter, as a liquid content. The trap bowl includes a transparent vertical prism. The transparent vertical prism includes a face that forms a vertical transparent surface facing against a content of the section. The face can provide a first angle of total reflection when content of the section is a type of gas, and a second angle of total reflection when the content of the section is the liquid content. A light source may emit a light beam incident on the face at an angle of incidence. The angle of incidence results in reflection of the light beam, striking the light receiver, when the face has the first angle of total reflection, and results in refraction of the light beam, missing the light receiver, when the face has the second angle of total reflection.

A livestock facility air filter grid system comprising perimeter vertical and horizontal stiffener plates and interlocking horizontal and vertical field stiffener plates which provides an improved sealed assembly and eliminates the potential for direct air by-pass of the filters.

Systems and apparatuses include a generator set including a chassis, an engine mounted to the chassis, an inverter coupled to the engine, and a housing coupled to the chassis. The engine and inverter are contained within the chassis and the housing. An air cleaner is sized to fit within the housing and includes an air cleaner housing defining an inlet and an outlet, and a sealing surface positioned between the inlet and the outlet, and a cover pivotably coupled to the air cleaner housing and including a carrier sized to be received within the air cleaner housing. The cover includes an air filter receiving feature structured to support an air filter and position the air filter between the inlet and the outlet, and a carrier flange structured to seal a portion of the air filter between the sealing surface and the carrier flange when the cover is arranged in a closed position.

An oil and air separator including a catch can with an inlet and an outlet thereto, the catch can adapted to remove oil from vapors entering the catch can via the inlet, and including an internal reservoir within which oil from the vapors entering the catch can may collect; and a check valve including a first end disposed within the internal reservoir, a second end, and a first fluid pathway therebetween in fluid communication with the internal reservoir, wherein vapors within the internal reservoir may exit the catch can through the first fluid pathway or a second fluid pathway including the outlet.

An air separation module includes a canister extending between a first end and an opposite second end, a separator fixed within the canister to separate a compressed air flow into an oxygen-enriched air flow fraction and an oxygen-depleted air flow fraction, and a one-piece cap. The one-piece cap is connected to the first end of the canister and has a filter module mount portion on a side of the one-piece cap opposite the separator to support a filter module with the air separation module. Nitrogen generation systems and methods of making air separation modules are also described.

An air cleaner disposed in an indoor space is disclosed. The air cleaner according to an embodiment of the present invention includes a blowing device including a suction port and a discharging port, a fan motor configured to cause air flow, a purification unit installed in the blowing device to clean air, a flow conversion configured to change a flow direction of air discharged from the discharging port, a communication unit configured to communicate with a moving agent moving in the indoor space, and a processor configured to receive feature information collected by the moving agent and associated with a structure of the indoor space, obtain a type of the indoor space by using the feature information, and control an operation of at least one of the fan motor and the flow conversion device by using the type of the indoor space to adjust at least one of an operation mode, a wind direction, and a wind volume.

A coalescence filter for purifying a fluid which contains a carrier and at least one liquid contaminant by coalescing of the at least one contaminant, where the coalescence filter includes an inlet for supplying the fluid to a filter element present in the coalescence filter, where the filter element includes a primary coalescence medium which is provided for coalescing of the at least one contaminant in the primary coalescence medium during the displacement of the fluid through the primary coalescence medium. The coalescence filter further includes an outlet for discharging the coalesced contaminant from the filter element, where the primary coalescence medium comprises at least one layer of a porous material, where the primary coalescence medium has a total thickness of at least 3.5 mm.
