Patent Images
1. A filter frame assembly comprising:
- a perimeter member surrounding a fluid aperture adapted to accommodate a fluid flow from an upstream direction to a downstream direction, the perimeter member comprising a perimeter upstream surface, a perimeter downstream surface, and a perimeter outer surface connecting the perimeter upstream surface to the perimeter downstream surface; and
a gasket carrier attached to the perimeter member and comprising a carrier outer portion facing generally away from the fluid aperture and a first outer portion sealing member projecting from the carrier outer portion.

34. A filter frame assembly comprising:
-
a perimeter member surrounding a fluid aperture, the perimeter member comprising a perimeter upstream surface, a perimeter downstream surface, and a perimeter outer surface connecting the perimeter upstream surface to the perimeter downstream surface; and a gasket carrier attached to the perimeter member by a snap feature and comprising a carrier upstream portion, a carrier downstream portion, and a carrier outer portion connecting the carrier upstream portion to the carrier downstream portion;
the gasket carrier further comprising;a first outer portion sealing member projecting outwardly from the carrier outer portion; a downstream sealing member projecting outwardly from the carrier downstream portion; and an upstream sealing member projecting outwardly from the carrier upstream portion; the snap feature comprising a recess on each of the perimeter upstream surface and the perimeter downstream surface, a protrusion projecting inwardly from the carrier upstream portion to snap into the recess on the perimeter upstream surface, and a protrusion projecting inwardly from the carrier downstream portion to snap into the recess on the perimeter downstream surface, wherein the gasket carrier is sufficiently resilient to bend to permit the protrusions and the recesses to snap together.

38. A filter frame assembly comprising:
-
a cage comprising a perimeter member surrounding at least two fluid apertures, the at least two fluid apertures being generally traversed by at least one primary cross member, at least one secondary cross member having a first end and a second end, and first and second wall members each having a first and second end, wherein each first end of each wall member is connected to the perimeter member and each second end of each wall member is respectively connected to the first and second ends of the at least one secondary cross member, the perimeter member comprising; a perimeter upstream surface, a perimeter downstream surface, and a perimeter outer surface connecting the perimeter upstream surface to the perimeter downstream surface; a gasket carrier attached to the perimeter member and comprising a carrier outer portion facing generally away from the fluid apertures and a first outer portion sealing member projecting from the carrier outer portion; and a filter element having at least four sections; wherein the cage generally surrounds the filter element, wherein the at least four sections of the filter element are arranged in a successive V-pattern having an open portion and a closed portion, wherein each open portion corresponds to a fluid aperture and each closed portion corresponds to a secondary cross member; and wherein each section of the filter element is secured in sealing relation to adjacent sections and to the cage. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45)
