A passive phase separator includes an inlet to receive two-phase flow into an inner conduit and an outer conduit. An annulus is formed between the inner conduit and the outer conduit. A hydrophobic screen separation device prohibits a flow of liquid from the two-phase flow into the annulus while allowing a flow of gas from the two-phase flow into the annulus, and a gas flow outlet releases the flow of gas from the annulus.

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.

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 filtration sealing system is provided for sealing a filter element in a housing at a mating interface therebetween. The sealing system includes a keyed interface. A replacement filter element is provided for such filtration sealing system, with the replacement filter element including a keyed interface.

A bathroom management apparatus may include a case having an air suction port formed in an upper portion of a front surface thereof, a first air discharge port formed in a lower portion of the front surface thereof, and a second air discharge port formed in a lower surface thereof. A suction vane opens or closes the air suction port, and first and second discharge vanes opens or closes the first and second air discharge ports, respectively. A duct is provided in the case to connect the air suction port, the first air discharge port and the second air discharge port to one another. A blowing fan is provided in the duct to suck air through the air suction port and blow the air to the first air discharge port and the second air discharge port. A heater heats the air in the duct.

A circular segment-shaped filter housing of a brake dust particle filter for a brake disk arrangement has first and second spaced-apart housing side walls. A housing circumferential wall connects the first and second housing sidewalls. The first and second housing side walls and the housing circumferential wall delimit an opening for receiving a brake disk of the brake disk arrangement. Delimitation parts are arranged at an end face edge of at least one of the first and second housing side walls and at an end face edge of the housing circumferential wall. The delimitation parts are detachable and exchangeable independent of the first and second housing side walls and/or of the housing circumferential wall. The delimitation parts delimit a free cross section area of the opening. A brake dust particle filter is provided with such a filter housing. A kit for producing such a filter housing is provided.

An exhaust aftertreatment unit for cleaning exhaust gases includes an emission reducing module being a diesel particulate filter, DPF, and/or a diesel oxidation catalyst, DOC, a selective catalyst reduction, SCR, catalyst, an electrical heating element arranged upstream of the emission reducing module, a casing housing at least the emission reducing module and the electrical heating element, and a service lid removably arranged to cover a service opening of the casing through which the emission reducing module may be accessed. The electrical heating element is removably arranged relative the casing and is arranged accessible upon removal of the service lid and the emission reducing module.

Disclosed is a method of filtering air in a closed work environment that includes placing a primary air filter assembly in the closed work environment, where the primary air filter assembly includes a first air input and a first air output. The first air output is poised to emit once-filtered air outside the closed work environment. The method also includes placing a secondary air filter assembly in the closed work environment, where the secondary air filter assembly includes a second air input and a second air output.

A filter for filtering particulates from a fluid stream includes a filter element, a first end cap, a second end cap, and a wrap. The end caps are respectively secured to the ends of the filter element to form a fluid tight seal therebetween. At least one of the end caps defines an opening therethrough in fluid communication with the interior passage of the filter element. The wrap is in the form of a strip secured to at least the filter element. The wrap comprises a conductive layer comprising an electrically-conductive material. The wrap is wrapped around the filter element such that at least forty percent of the outer surface area is covered by the conductive layer.

A device for filtering air for a user comprising a frame formed in a generally oval-shaped band, the band encircling the user's head, with an upper portion extending above and behind the user's ears and a lower portion extending below and in front of the user's ears. The device includes components mounted to the frame, comprising an air intake filter mounted on the frame and communicating on one side with ambient air outside the device and on the other side with an inlet duct and an air outlet filter mounted on the frame and communicating on one side with air inside the device and on the other side with ambient air outside the device. The device also includes a battery-powered air mover mounted on the frame and operable to pull air through the air intake filter and through the inlet duct and push air out into the inside of the device and a rechargeable battery mounted on the frame to power the air mover. The device further includes a transparent face shield mounted on one side of the frame in such a way as to create an airtight seal between the face shield and the one side of the frame, a fabric component made from an air impermeable fabric and mounted on the other side of the frame in such a way as to create an airtight seal between the fabric component and the other side of the frame, and to encircle the user's neck, a head harness configured to rest on the user's head and support the frame with its components mounted thereon, and wherein the components are mounted on the upper portion the frame and on the lower portion of the frame so as to achieve a weight distribution ratio between the upper portion of the frame with components mounted thereon and the lower portion of the frame with components mounted thereon, the ratio being between 1 to 1.5 and 1.5 to 1.
