Abstract
A backflow blocking apparatus for axial fans may be provided. The apparatus may comprise a sheet. The sheet may comprise a first section and a second section. The first section may comprise a plurality of flaps cut out of and retained by the first section of the sheet. The second section may comprise a guard structure. The apparatus may further comprise a fold about which the first section and the second section are folded on one another. The guard structure may inhibit the movement of the plurality of flaps in a direction toward the guard structure when the first section and the second section are folded on one another.
