Abstract: A shelf assembly can comprise a plurality of stanchions, each stanchion having an axis of elongation and comprising a pair of generally parallel legs that define a slot therebetween and respective front edges. A shelf can have an underside and an opposed upper surface that defines a plane. The shelf can be pivotably coupled to the stanchions about an axis about and between a stowed position and a use position. The axis can extend through the plurality of stanchions at a location above the plane when the shelf is in the use position. At least one biasing element can be disposed at least partially within the slot and configured to bias the shelf toward the stowed position.

Abstract: A primary filter cage wall element is adapted to form, together with at least one complementary filter cage wall element, a tubular baghouse filter cage segment. The filter cage wall elements are provided with snap-locks, for snapping a first long side of the primary filter cage wall element to a second long side of the complementary filter cage wall element, and for snapping a second long side of the primary filter cage wall element to a first long side of the complementary filter cage wall element.

Abstract: A filter support cage for a baghouse filter comprises a first filter cage segment comprising elongated body portion having a top end and a bottom end, a second filter cage segment comprising a second elongated body portion having a top end and a bottom end, and a coupling member positioned between and connecting the bottom end of the first filter cage segment and the top end of the second filter cage segment.
