A system including the housing is also provided. Methods of providing biosecurity for animal confinements are also provided. | 12-05-2013 |
20130269531 | Membrane-Free Filter and/or Integral Framing for Filter - A filter for an electronics cooling unit of a telecommunications base station, the electronics cooling unit adapted to receive fresh air into a housing of the cooling unit through an opening communicating with the external environment. The filter includes a structural support configured to be mounted to said housing, a gasket sealingly engaging the structural support and adapted to engage the housing; and a filter media supported by the structural support, the filter media being free of a membrane type layer and including a fiber entanglement selected to prevent ingress of water sufficient to pass a salt fog test consistent with GR-487-CORE and in accordance with ASTM B 117. | 10-17-2013 |
20120318144 | FILTER FRAME HOUSING AND FILTER FOR ANIMAL CONFINEMENT BUILDING - A filter assembly including a rectangular inlet frame having a rectangular inlet opening to receive a primary filter and optional a prefilter. The filter assembly may include a rectangular outlet frame and a housing body that is collapsible to have a flattened shipping state and an erect state. The rectangular inlet frame may also be used as a housing by itself to support and house primary filters and prefilters. A gridwork including one or more grid dividers may be used in the rectangular inlet frame to provide 2 or more openings for receipt of filters. | 12-20-2012 |
20120317941 | FILTER SYSTEM USING PLASTIC FRAMES ALONG STRUCTURAL WALL OF ANIMAL CONFINEMENT BUILDING - A filter assembly including a rectangular inlet frame having a rectangular inlet opening to receive a primary filter and optional a prefilter. The filter assembly may include a rectangular outlet frame and a housing body that is collapsible to have a flattened shipping state and an erect state. The rectangular inlet frame may also be used as a housing by itself to support and house primary filters and prefilters. A gridwork including one or more grid dividers may be used in the rectangular inlet frame to provide 2 or more openings for receipt of filters. | 12-20-2012 |
20120291406 | V-Bank Air Filtration System Such as for Animal Confinement - A filter system includes a housing having an inlet opening surrounded by a sealing surface, an outlet opening. The housing may be rotational molded or be configured to be nestable with additional housings for shipping purposes. The system may also be configured such that the filter to be mounted therewith can be placed interior to the filter housing during shipment. A V-bank filter or a single-header box filter is positioned in the inlet opening, has a flange in general alignment with the sealing surface, and a plurality of filter media sections projecting away from the flange and into the housing interior. A seal is disposed between the flange of the V-bank or single-header box filter and sealing surface. A pre-filter, such as a panel filter, may be provided upstream from the primary filter. | 11-22-2012 |
20120167535 | SELF SUPPORTED PLEATED PANEL FILTER WITH FRAYED MEDIA EDGES - A panel filter is provided such as for HVAC applications in which one of the cut edges is frayed and attached with adhesive to the inner peripheral surface of a paper board frame. The frayed edges may facilitate better gluing of pleated filter medium to the frame especially for self-supported filter media applications and may increase structural rigidity and sealibility as a whole. Frayed edges also provide flexibility to assist in installation of a card of pleated filter medium into a paper board frame. | 07-05-2012 |
20110057022 | Box/Carton for Shipping Filter Cartridges - A shipping and display carton is provided that may be used for panel filters.
