Filter assemblies are described and shown. Components, features and methods of assembly and use are described. Many of the principles relate to preferred cartridge configurations for engagement with selected housings. Selected optional features described can be used to provide indication to a service provider that a proper cartridge is not positioned appropriately in the housing for use.

Various example embodiments relate to rotating coalescers. One embodiment includes a housing comprising a first housing section having a blowby gas inlet structured to receive crankcase blowby gases from a crankcase. The housing further comprises an oil outlet. The rotating coalescer includes an endcap and filter media. The filter media is arranged in a cylindrical shape and is coupled to and positioned between the first housing section and endcap. The filter media is structured to filter the crankcase blowby gases passing through the filter media by coalescing and separating oils and aerosols contained in the crankcase blowby gases. The rotating coalescer includes a hollow shaft extending through the housing and positioned radially inside of the filter media. The hollow shaft forms a blowby gas outlet structured to route filtered crankcase blowby gases out of the housing. The rotating coalescer further includes a drive mechanism operatively coupled to the hollow shaft.

A filter baffle assembly, including a filter cap engageable to a mouth of a container, the filter cap including a filter vent operatively attached to a liner situated within an inner space of the filter cap, and a gas permeable baffle disposed between a mouth of the container and the filter vent, covering the filter vent, the baffle including a single perforation to permit gas exchange between an interior of the container and the filter vent, and to protect the filter vent from contact with contents housed in the interior of the container. A gas permeable point baffle for protecting a filter vent from contact with the contents of a container, including a single perforation, the point baffle being welded to a liner and covering a filter vent operatively attached to the liner, housed within a cap engageable to the mouth of the container. A method for protecting a filter vent from the contents of a container.

In order to solve the problem of providing an improved hob assembly which can be integrated into kitchen furniture of any type in a particularly easy manner, a hob assembly is proposed which includes at least one cooking zone, at least one air-purifier device arranged beneath the cooking zone, and at least one connecting element for connecting the cooking zone to the air-purifier device such that air can be conducted from the cooking zone to the air-purifier device via the connecting element, wherein the connecting element is arranged on the cooking zone in a mechanically removable manner and is height-adjustably mounted in the air-purifying device.

A portable air filter and method of use are provided. The portable air filter includes a semi-permeable air filter, optionally disposed within a frame. An attachment surface, such as an adhesive, is disposed on the frame, for attaching the portable air filter to an air vent. In certain embodiments, a second air filter and frame are slidably connected to the frame. If the portable air filter is not disposed within a frame, the portable air filter is cut to fit over an air vent, and an adhesive, such as tape, is provided for a user to attach the cut filter to fit over the air vent. The method includes attaching the portable air filter to an air vent by pressing the adhesive to a wall, ceiling, or floor such that the portable air filter covers the air vent. The invention is useful for improving air quality in a variety of spaces, including in an airplane, in a hotel, on a cruise ship, on a travel bus, and other public spaces.

A ventilating device including: a frame provided with an air inlet and an air outlet, an air blowing unit for directing air, a control circuit board for controlling the air blowing unit, an operation switch for adjusting a rotating speed of the air blowing unit, and a circuit board box for accommodating the control circuit board. The circuit board box includes: a first accommodating portion in which the operation switch is housed and a second accommodating portion in which the control circuit board is housed. The first accommodating portion includes: a first opening that functions as an operation port; and a panel for covering the first opening. The frame is provided with a second opening opposite to the first opening. The panel is exposed from the second opening to exterior of the frame. A sealing portion is provided around the first opening.

An NBC filtration system whose main components are a filter unit, a blower, a manual air exchange backup unit and a changeover valve. The filter unit is elongated horizontally positioned along a top portion of a wall of the protected space. Inlet and outlet ports of the filter unit are located close to each other near a first extremity of the filter unit. The blower is driven by the electric motor through a second speed increasing transmission enabling rotation of an impeller of the blower. The blower is positioned along the filter unit near a second extremity distal from the inlet and outlet ports; The changeover valve has a tubular housing extending along the filter unit near the first extremity, and an internal displaceable tubular valve member. Each of the components may be replaced with a component of different capacity without effecting the other components.

A vent filter and a Radio Remote Unit having the vent filter. The vent filter includes a first member including a first body having a ventilation path extending through the first body, an inner wall constituting a ventilation hole which is communicated with the ventilation path, and an outer wall constituting a gap between the inner wall and the outer wall. The vent filter also includes a second member including a second body and at least one enclosure wall protruding out from the second body, wherein at least one of the at least one enclosure wall is located outside the outer wall and surrounding the outer wall. Both the inner and outer walls have at least one first groove at an end and each of the at least one enclosure wall has at least one second groove at an end.

Apparatuses, systems, and methods are provided for and in conjunction with an oil coalescing breather which may comprise a breather housing with a standpipe for at least receiving an air flow containing oil, a first end, a second end, and a molded coalescing material. The first end may be configured for at least receiving the air flow containing oil into the standpipe. The second end may be located at an opposite side of the standpipe from the first end and be configured for at least emitting air from the standpipe. The molded coalescing material may be positioned in the standpipe and comprise a plurality of openings enabling the air flow from the first end there through. Each of the plurality of openings is large enough to allow coalesced oil from the air flow there through to fall into the first end under a force provided by gravity.
