摘要： Provided are an air filter medium that can be reused with a small decrease in performance by performing a disinfection treatment, a pleated pack, an air filter unit, a mask filter medium, and a method for regenerating an air filter medium. An air filter medium (30) including a fluororesin porous membrane (31) and a supporting member (32) stacked on top of each other has a permeability ratio (permeability after disinfection treatment/permeability before disinfection treatment) of 5.0 or less, the permeability ratio being a ratio of permeabilities of the air filter media (30) before and after the disinfection treatment of the fluororesin porous membrane (31) as determined using NaCl particles having a particle size of 0.1 µm, and a pressure loss ratio (pressure loss after disinfection treatment/pressure loss before disinfection treatment) of 0.83 or more and 1.15 or less, the pressure loss ratio being a ratio of pressure losses of the air filter media (30) before and after the disinfection treatment of the fluororesin porous membrane (31).

An ambient air treatment system for a vehicle, a vehicle, and a cooling system for a vehicle comprising said filter element. A method for producing a filter element, comprising: defining boundary conditions comprising element geometry boundary conditions and filter media boundary conditions; computing a pressure loss for a plurality of different virtual filter elements selected from within the boundary conditions; selecting a subset of the plurality of virtual filter elements for which a pressure loss is within a predetermined range of speed or a variable that is derivable therefrom, wherein each filter element is characterized by a filter parameter set comprising element geometry parameters, filter media parameters, pressure loss, and pressure loss; selecting one virtual filter element of the subset, retrieve the properties of the one virtual filter element and electing a filter media having properties of about the one virtual filter element; and producing a filter element having the geometry of about the one virtual filter element.

摘要： An air cleaner assembly is disclosed. In one aspect, the air cleaner assembly includes a housing defining an inlet and an outlet, and including an access opening between the inlet and outlet. The air cleaner also includes a filter cartridge received within the housing and covering the access opening. The air cleaner also includes a lock mechanism. The lock mechanism is movable between an unlocked position in which the filter cartridge can be installed and removed from the housing and a locked position in which the filter cartridge is secured within the housing. The filter cartridge and lock mechanism include interacting features allowing the lock mechanism to be moved from the unlocked position to the locked position only when the filter cartridge is installed within the housing.

摘要： [Problem] To provide a filter pack capable of suitably maintaining pleat spaces while suppressing an increase in pressure loss, and an air filter including the filter pack.
[Solution] The filter pack incudes a filter medium having folds alternately repeated on upstream and downstream sides of airflow by a pleating process, at least one pair of upstream ventilation surfaces facing each other via the fold on the downstream side therebetween and into which the airflow flows, and at least one pair of downstream ventilation surfaces facing each other via the fold on the upstream side therebetween and from which the airflow flows out, and a plurality of space maintaining members formed on each of the upstream ventilation surfaces and each of the downstream ventilation surfaces to maintain spaces of each pair of upstream ventilation surfaces and each pair of downstream ventilation surfaces. The plurality of space maintaining members formed on the upstream ventilation surfaces are intermittently formed in a direction orthogonal to the fold. At least one space maintaining member formed on one side of the pair of upstream ventilation surfaces is in contact at two or more places with at least one space maintaining member formed on the other side of the pair of upstream ventilation surfaces.

Die Kassettenaufnahme (7) ist mit einer Luftdurchtrittsöffnung (16) versehen, die gegenüber einer Luftdurchtrittsöffnung der Filterkassette (6) mit wenigstens einem zweiten Dichtelement (26) abgedichtet ist. Die beiden Dichtelemente (26, 37) liegen unter einem spitzen Winkel entgegengesetzt schräg zu einer Längsmittelebene der Filtereinheit bzw. der Filterkassette (6).
Die Filterkassette (6) kann in eine Aufnahmeeinheit eingesetzt werden, die einen die Filterkassette (6) aufnehmenden Halteteil (41) aufweist, der vorteilhaft ein Rahmen ist, der die Filterkassette (6) umgibt.
