Abstract: A V-bank air filter having a high air flow rate with low pressure drop is provided. In one embodiment, a V-bank filter includes a first side panel and a second side panel having parallel first edges oriented perpendicular to a flow direction through the filter. A plurality of filter elements are arranged in at least two pairs of vees extending between the first and second housings. The side panels and the filter elements comprise a unitary disposable filter, wherein at least three filter elements have a unique orientation relative to the flow direction.

Abstract: A method and apparatus for economically filtering air into swine farms and other animal enclosures are provided. Advantageously, the invention substantially reduces the risk to airborne transfer of disease into animal enclosures. In one embodiment, a method for providing clean air to an animal enclosure includes providing an animal enclosure having an animal containing volume for containing a plurality of animals, removing air from the internal volume via at least one exhaust fan, and filtering air being pulled into the enclosure by the at least one exhaust fan using a fully sealed filter, the fully sealed filter having a particle separation sufficiently efficient to prevent detection of live (PRRS-) virus downstream of the filter, using polymerase chain reaction (PCR) analysis of samples collected with a cyclonic aerosol collector.

Abstract: A pocket filter assembly includes a frame structure having a plurality of filter pocket openings and a corresponding plurality of filter pockets, each filter pocket having a pocket mouth securely sealed in a corresponding filter pocket opening. The frame structure includes an outer subframe and a corresponding inner subframe connected and locked to each other by means of locking elements at locking positions distributed along opening portions of the subframes defining the filter pocket openings. At each locking position, the filter pocket mouths are sealed clamped and sealed between co-operating opening portions of the subframes. The locking elements include an undercut hook-shaped projection on the inner subframe and a co-operating receiving hole on the outer subframe, such that an interlock of the subframes to each other is obtained, while including filter pocket mouth material of the associated filter pocket between said projection and said aperture such that said interlock is sealed thereby.

Abstract: A pocket filter assembly comprises a frame structure having a number of filter pocket openings (3) and a corresponding number of filter pockets (2), each filter pocket having a pocket mouth sealingly secured in a corresponding filter pocket opening. The frame structure comprises an outer subframe (15,16,17) and a corresponding inner sub-frame (14) connected and locked to each other solely by means of locking elements at distributed locking positions along opening portions of the subframes defining the filter pocket openings. At each locking position, the filter pocket mouths are sealingly clamped between co-operating opening portions of the subframes.

Abstract: Embodiments of the invention generally include a filter assembly having a media pack having a single web of pleated media having at least two mini-pleated regions arranged in non-linear orientation. In one embodiment, a filter assembly includes a media pack defined by a single web of media, and an adhesive layer coupling a flat end of the media pack to a frame assembly to form a lap joint. In another embodiment, a filter assembly includes a media pack sealed to a frame assembly. A discontinuous layer of adhesive couples at least one edge of the media pack to the frame assembly.
