Abstract: An air filtration cassette extending in a length direction between a first end and a second end, related to an intended air flow direction from the first end to the second end during use, the air filtration cassette comprising a filter material disposed between an outer boundary surface and an inner boundary surface, the air filtration cassette having an interior open space encompassed by the inner boundary surface and the filter material, and having an opening arranged at one end of the open space and being closed at the other end thereof, an average distance between said inner boundary surface and said outer boundary surface at said second end being larger than an average distance between said inner boundary and said outer boundary at said first end, the average distance between said inner boundary surface and said outer boundary surface being the average of all distances between the inner boundary surface and the outer boundary surface in a direction perpendicular to said length direction at a selected pos

Abstract: The present disclosure relates to pleated filter element comprising: a pleated filter media comprising a major upstream face and a major downstream face and comprising a plurality of oppositely-facing pleats extending between said major upstream face and said major downstream face such that the pleated filter media comprises a first corrugated edge and a second corrugated edge and a first noncormgated edge and a second noncormgated edge, wherein the pleated filter media comprises a main pleat section and a first edge pleat section at the first noncormgated edge, wherein the length of the first edge pleat section is less than 50% of the total length of the pleated filter element between the first noncormgated edge and the second noncormgated edge, and/or wherein the maximum pleat height in the first edge pleat section is lower than the maximum pleat height in the main pleat section. The present disclosure further relates to an air filter comprising the pleated filter element in a casing.

Abstract: The disclosure relates to a sealing arrangement comprising a gasket arranged to seal a gap formed between a first element and a second element, wherein the gasket is arranged to be located in the gap and to be in contact with the first and the second elements, where the gasket comprises two elongated gasket members located on a distance from each other so as to form an intermediate gasket space confined by the gasket members and said first and second elements, and in that the sealing arrangement further comprises a pressure source adapted to apply a pressure on the intermediate gasket space, said pressure source preferably being configured to maintain a set pressure difference towards the surroundings. The disclosure further relates to a method, a system, a computer program product arranged to perform the method, a further sealing arrangement and a further method of monitoring sealing integrity of a pharmaceutical production space.

Abstract: An air filter assembly and use thereof for filtration of air in wet or damp conditions, said air filter assembly comprising: an air filter comprising a front frame defining at least one rectangular aperture for receiving an air flow to be filtered; characterized in that said air filter assembly comprises a deflector element extending alongside edge portion of the rectangular aperture and adapted an to deflect an air flow passing through the rectangular aperture away from an adjacent inside surface of the air filter; and a liquid drain arranged such that liquid collected at said adjacent inside surface of the air filter can exit the air filter through said liquid drain.

Abstract: A test probe for filter leakage detection. The test probe (1) has an elongated housing (5) with a longitudinal inlet portion for admitting gas into a first chamber of the housing through an inlet of the inlet portion, and an outlet portion for letting gas out of a second chamber of the housing through an outlet of the outlet portion. Further, the test probe has an intermediate element comprising a throttling portion. The intermediate element is arranged between the inlet portion and the outlet portion, wherein the first and second chambers are fluidly interconnected via the throttling portion, wherein the throttling portion is elongated and extends longitudinally of the housing, wherein the throttling portion is arranged to cause a smaller vacuum upstream of the throttling portion than downstream of the throttling portion when gas is sucked through the test probe.

Abstract: The present invention relates to a filter frame for receiving a media pack, the filter frame comprising a front plate, and first and second gable plates arranged at opposite ends of the front plate. The front plate comprises a groove at each of the ends and a front edge portion of each gable plate is received in a respective one of the grooves. Each gable plate comprises a retainment member arranged at the front edge portion, which retainment member has been engaged with a complementary retainment member of the front plate. The invention also relates to a filter assembly and a method for assembling a filter frame.
