A blow-by gas filtration assembly has an axis and includes a main body having a filtration chamber fitted with an outlet mouth at the axis. A filter group extends along the axis having a hollow cylindrical shape with a central chamber. An engine group operatively connects to the filter group for controlling its rotation about the axis. The engine assembly includes a rotor and a stator. A support and control shaft formed as a hollow body extends along the axis and includes an engine portion on which the rotor integrally mounts and a filter portion on which the filter group integrally mounts so that controlled rotation of the rotor corresponds to rotation of the shaft and thus of the filter group. The filter portion includes an outlet duct of the filtered blow-by gases inside which the outflow of the filtered blow-by gases towards the outlet mouth takes place.

Methods and apparatus for sterilization are presented. An exemplary embodiment includes a sterilizing cabinet assembly. The sterilizing cabinet includes a cabinet having an access port, a door connected to the cabinet, the door moveable between an open position permitting passage through the access port to an interior of the cabinet and a closed position precluding passage through the access port. The sterilizing cabinet assembly also includes at least one of the cabinet and the door having a vent port. The sterilizing cabinet has a primary filter overlying the vent port and forming a sealed interface with an adjacent portion of the one of the cabinet and the door and a secondary filter overlying at least a portion of the primary filter.

A vacuum insulated structure includes a first panel having an inner surface defining an area. The first panel includes a vacuum port. A trim breaker interconnects the first panel with a second panel in an air-tight manner to define a vacuum cavity therebetween. A first filter member is disposed on and substantially covers the area of the inner surface of the first panel and the vacuum port of the first panel. A second filter member substantially covers the first filter member to define a channel therebetween. The channel includes an area commensurate with the area of the inner surface of the first panel. The first panel may also include a mesh member covered by a filter member to define a channel therebetween to improve evacuation time using the channel to evacuate the vacuum cavity.

A vent assembly (100) has a vent body (110) defining a first end (104) and a second end (106), a central axis extending from the first end to the second end, and an inner surface defining a cavity. A first retainer extends across the cavity towards the first end of the vent body, and a second retainer (140) extends across the cavity towards the second end of the vent body. The first retainer defines a first retainer opening extending to a first radial distance from the central axis, and the second retainer defines a second retainer opening extending to a second radial distance from the central axis, where the second radial distance is greater than the first radial distance. Coalescing filter media is disposed in the cavity between the first retainer and the second retainer. The coalescing filter media, the cavity, the first retainer, and the second retainer cumulatively define an airflow pathway.

A vent having a continuous, elongate mat having an upper face and a lower face, and having a first portion and a second portion. The mat includes a plurality of columns of patterned three-dimensional structures of a network of randomly convoluted polymeric filaments having a first density, at least one of the plurality of columns of patterned three-dimensional structures being provided in the first portion, and at least one other of the plurality of columns of patterned three-dimensional structures being provided in the second portion. The mat includes a throat portion between the first portion and the second portion, the throat portion having a network of randomly convoluted polymeric filaments of a second density different than the first density, a first cover layer covering an outer edge of the first portion, and a second cover layer covering an outer edge of the second portion.

A kitchen appliance has a compressible filter media block for removing odor-causing contaminants from cooking fumes. The sintered-fiber media exhibits low pressure drop and high flow rate. Embedded sorbent particles are adhered to the media block, preferably via sintering, thus leaving a substantial proportion of adsorbent surface area exposed for filtration purposes. The media block can be elastic or viscoelastic making it useful in retrofit applications for use in filtration circuits not originally designed to accommodate a filter. In preferred embodiments, the media block is composed of sintered plastic fibers wherein the sorbent particles are adhered thereto via sintering.

The first panel may also include a mesh member covered by a filter member to define a channel therebetween to improve evacuation time using the channel to evacuate the vacuum cavity.

The present invention relates generally to a passenger compartment air vent filtering device. More specifically, the invention includes a cover that can be placed over top of an existing air vent in a passenger seating compartment to filter the air flowing therefrom, and comprises both a HEPA filter and a UV light disinfection filter. In a preferred embodiment, the novel air vent filtering device further comprises a moveable element, a plurality of LED lights and a scent diffuser.

This present invention relates to a unique HVAC air filter holder designed to prevent or reduce air from escaping or otherwise bypassing the HVAC air filter. The HVAC air filter holder comprises a filter securing device, and is a material that is compressible, moldable, expansible or the like such that it can be secured around the perimeter of the air filter.

The facility includes a first connection mechanism connecting a filter unit to a floor discharging section to establish communication between an opening portion of the floor discharging section and an upper face opening portion of the filter unit and a second connection mechanism connecting the filter unit to an exhausting chamber to establish communication between an opening portion of the exhausting chamber and a side face opening portion of the filter unit. The first connection mechanism includes a seal portion that comes into contact with an entire circumference of an outer face of an upper end portion of the filter unit, thus preventing leakage of exhaust gas. The seal portion includes an introducing portion for introducing the upper end portion of the filter unit to the seal portion from a horizontal direction.
