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 demister apparatus for machine tools having an enclosure booth for confining mist in which a varying outflow of air is drawn from the booth and directed to a remote demister apparatus from a minimum when the access doors to the enclosure are closed to a maximum when one or more of the doors are opened. The air flow may also be varied with the number of machine tools in operation as well with the state of filters in the remote demister apparatus. A cyclonic separator is also provided adjacent to the booth which functions well in a vertical up flow mode over a range of air outflow rates of flow.

An air oil separator includes a removable and replaceable filter element. The filter element can include a flange-receiving recess in a first end cap construction. Alternatively, the first end cap construction can include alternating radially protruding projections and radially inward recesses. Alternatively, the end cap construction can include a first section contained within a plane and a second section sloping from the first section.

A droplet coalescing filter cartridge is provided. The filter cartridge includes an outer filter tube and an inner filter tube disposed within the outer filter tube, and is configured to provide parallel filtration of a fluid flow. The filter includes a depth media configured to coalesce fine droplets or aerosols from an air flow. The filter cartridge is suitable for use in a coalescing filter assembly including the filter cartridge and a secondary filter element.

A separation component for a filter element has a web-shaped support body with a top rim and a bottom rim. A web-shaped separator body covers a side face of the support body completely or partially. Support body and separator body are wound to a spiral shape with axially successive turns. The support body has a connecting fold at the top rim and at the bottom rim, respectively. The connecting folds engage each other in the axially successive turns of the spiral shape. The separation component can be manufactured by placing a web-shaped separator body onto a web-shaped support body and by winding support body and separator body to a spiral shape. During winding, a connecting fold at a top rim of a turn of the spiral shape and a connecting fold at a bottom rim of an axially successive turn are brought into engagement with each other.

The present disclosure relates to a process for removal of an aerosol, comprising the steps of directing a process gas comprising an aerosol to contact an inertial demister providing a first demisted process gas, and directing the first demisted process gas to contact a coalescing demister providing a second demisted process gas, characterized in said first inertial demister being more open than said coalescing demister, where more open is defined as having a higher void fraction or a lower density with the associated benefit of such a process providing an efficient removal of a large volume of liquid from the inertial demister, while avoiding flooding of the demister system. It further relates to a process plant for sulfuric acid production employing such a pair of demisters.

A coalescing filter assembly including a coalescing filter element is provided. The coalescing filter assembly includes a base housing and a cover housing that together form a coalescing chamber. Disposed within the coalescing chamber is the coalescing filter element. The coalescing filter element includes a frame with a partition that separates an unfiltered side from a filtered side of the coalescing filter assembly. A port connects the unfiltered side to the filtered side through the partition. A coalescing tube including coalescing filter media is connected to the port. Unfiltered fluid that enters the coalescing filter assembly is passed through the coalescing filter media such that the contaminants are removed to create a filtered fluid. The filtered fluid exits the coalescing filter assembly at an outlet of the coalescing filter assembly.

A separating apparatus for separating liquid from gas has a housing with a connection device for connecting to a connection head of a machine along a connection axis. The housing has a gas inlet and a gas outlet surrounding the connection axis. A separating medium inside the housing separates gas inlet from gas outlet. A liquid collection chamber inside the housing at a clean gas side surrounds connection axis and gas outlet. A liquid drain leads out of the liquid collection chamber. Gas outlet and liquid drain lead out of the housing at a side provided with the connection device. A pipe section arranged inside the housing surrounds circumferentially the connection axis and forms at least partially a radially inner boundary of the liquid collection chamber. The pipe section leads to the gas outlet. The pipe section is functionally separated from mechanical force-transmitting connection elements of the connection device.

The technology disclosed herein relates to a vent assembly having a vent housing that defines a first airflow pathway, a second airflow pathway, and a third airflow pathway. The first airflow pathway is configured for fluid communication with an interior of an enclosure. The second airflow pathway is configured for fluid communication with the external environment, and the third airflow pathway extends between the first airflow pathway and the second airflow pathway. A membrane is coupled to the vent housing such that the second airflow pathway and the third airflow pathway are in communication through the membrane. Coalescing filter media is disposed within the vent housing such that the third airflow pathway and the first airflow pathway are in communication through the coalescing filter media. The vent assembly defines a spacing region between the coalescing media and the membrane.

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.
