Air filter construction
First Claim
1. An improved V-cell filter construction for emplacement within a walled conduit through which a contaminated air stream passes and comprising:
- (a) a plurality of separate, V-shaped wire mesh members arranged in side-by-side relationship presenting a plurality of V-shaped cells extending across said walled conduit in the path of said air stream, each of said wire mesh members having lateral edges thereof positioned on the upstream side of said filter construction;
(b) a connecting means for engaging and holding in position the corresponding lateral edges of adjacent wire mesh members, said connecting means including a pair of spaced, outer trackways into which said lateral edges extend and means for retaining said lateral edges therein;
(c) a plurality of separate, fibrous, filter media members folded into a generally V-shape and of a size, shape, and number generally corresponding to the size, shape and number of said V-cells, one of said filter media members inserted into each of said cells;
(d) said connecting means further including a central trackway opening in the opposite direction from said outer trackways and of a width less than the combined thickness of two of said filter media members; and
(e) the lateral edges of each of said filter media members extending around the sides of said connecting means and into said central trackway and retained therein.

Abstract
A plurality of separate V-shaped wire mesh members are arranged and connected in side-by-side relationship to provide a plurality of V-shaped cells across an air stream. A W-shaped retainer or connector formed of perforated sheet metal has outer, downstream facing trackways which receive side edges of the wire mesh members, and a central, upstream facing trackway which receives and retains the free edges of V-shaped filter media bags which are inserted into the V-shaped cells overlying the wire mesh. A stabilizer bar extends across and attaches to the exposed adjoining edges of the V-cells to support the cells in proper relation and retain the filter media in place.
