Abstract
A filter holding frame that may be used agricultural environments. The filter holding frame may include a plurality of interconnecting members with an upstream hemmed edge and downstream opposing flanges. The opposing flanges of the members may define a sealing face configured for a plurality of air filters. The members of the outer periphery of the filter holding frame may include the mounting surface and the sealing face.
Claims18
A filter holding frame comprising:
- a plurality of intersecting members defining an outer periphery of said filter holding frame and a plurality of filter cells;
- each member includes an upstream hemmed edge extending towards downstream opposing flanges, wherein said downstream opposing flanges extend outwardly away from said upstream hemmed edge;
- said downstream opposing flanges define said outer periphery of said filter holding frame and a sealing face within each said filter cell;
- and
- wherein the downstream opposing flanges define the outer periphery and the downstream opposing flanges and the sealing face within each said filter cell are substantially in the same plane.
