摘要:
An incubator for cell and tissue culture under controlled atmospheric conditions has a primary air flow control device that forms a primary, preferably laminar flow, air veil across an opening that allows access to the cells or tissue cultures disposed within the incubator. Preferably, most if not all of the air in the primary (laminar flow) air veil is recirculated, and a secondary air flow control device is used that forms a secondary, preferably laminar flow, air veil between the primary (laminar flow) air veil and a user of the incubator.

An air intake includes an air channel for an air stream passing through the air intake into the plant, and a particle filter assembly arranged in the air channel for removing particles from an air stream passing through the air channel, the particle filter assembly including a front and a back filter unit. The front filter unit is arranged before and in series with the back filter unit such that an air stream passing through the air channel passes through the front filter unit before passing through the back filter unit. The front filter unit is removable and replaceable by a fresh front filter unit while the back filter unit remains in the air channel and while an air stream is passing through the air channel during operation of the plant. The front filter unit has at least equal efficiency and dust holding capacity as the back filter unit.

An indoor unit (200) for an air-conditioning apparatus includes a cartridge (50) provided to an air inlet (2) so as to be freely mountable and dismountable. The cartridge (50) accommodates a filter (40) so as to be freely movable in a right-and-left direction and has an opening port (60) formed in one end portion in the right-and-left direction. A dust box (90) is provided on a side of the end portion of the cartridge (50). The dust box (90) includes a cleaning mechanism (110) configured to clean the filter (40) and a dust collecting portion (91) configured to collect dust.
摘要:
A filtration article including a composite filtration structure, a seal region positioned within the composite filtration structure, and an attachment weld that interconnects the seal region and an outer casing is provided. The composite filtration structure includes a stacked filter material including at least two fluoropolymer membranes and a support layer. The support layer may be formed of a thermoplastic or thermoset polymer. When heated, the polymer in the support layer melts and flows into the fluoropolymer membranes. In exemplary embodiments, the polymer is imbibed through the thickness of the fluoropolymer membranes. The attachment weld may be positioned at any location within the seal region so long as the attachment weld is positioned a distance from the outer periphery of the composite filtration structure. The filtration article is small in size, is lightweight, and may be used as a sterilizing grade filter. Methods of producing the filtration article also provided.
摘要:
A plate-type filter element has a filter-medium body and a seal surrounding the filter-medium body, said seal fitting sealingly against a first sealing surface that is on the filter housing side and that extends on a filter-element plane, a sealing handle, designed to fit sealingly against a second sealing surface on the filter housing side, being connected to the surrounding seal, said second sealing surface extending at least partially outside the filter element plane.

A filter device for gas filtration has a plate-type filter element in a filter housing that can be closed by a housing cover. The filter element is provided with a cavity which forms a clean-side gas collection chamber and in the gas collection chamber a through-bolt is guided through a sealing eyelet, which is connected to a sealing element on the clean side of the filter element, in order to connect the cover element to the filter housing.
摘要:
Die vorliegende Erfindung betrifft eine Filtervorrichtung, insbesondere Rauchgas - oder Staubfiltervorrichtung, mit einem Gehäuse (2), einem Einlass (3) für das zu filternde Medium, einem Auslass (4) für das gereinigte Medium und mindestens einem Filter (8), der in dem Gehäuse zur Abtrennung der aus dem Medium zu filternder Stoffe angeordnet ist, wobei die Filtervorrichtung weiterhin eine Hohlwelle (5) mit einem Hohlwelleninnenraum aufweist, wobei die Hohlwelle drehbar in dem Gehäuse aufgenommen ist und mit dem Auslass verbunden ist oder diesen bildet, wobei der Filter als Filterscheibe (8) ausgebildet ist, und wobei die Filterscheibe Filtermaterial und einen Hohlraum aufweist, der zumindest teilweise von dem Filtermaterial umgeben und mit dem Hohlwelleninnenraum verbunden ist, sodass das zu reinigende Medium über den Einlass in das Gehäuse, durch das Filtermaterial in den Hohlraum des Filters und vom Hohlraum des Filters zum Hohlwelleninnenraum und von da zum Auslass gelangen kann. Weiterhin betrifft die Erfindung ein Verfahren zum Betrieb einer derartigen Filtervorrichtung.
