Air intake filter screen assembly

A filter screen assembly for use with an air intake structure, the structure including a face within which is formed an air intake opening, said filter screen assembly comprising:

• a screen including a flexible mesh material and about which extends an outer perimeter edge, a plurality of perimeter defined apertures in said screen each further comprising a grommet:
• a plurality of fasteners projecting from locations of an intake face surrounding the intake opening and engageable through said perimeter edge for securing said screen to the air intake face, said fasteners each further comprising an end-projecting component insertable through an aligning grommet and rotatable about an axis extending perpendicular to a surface of the air intake;
• and
• said perimeter edge being secured at specified locations against the face of the air intake structure in order to prevent air from bypassing the air permeable material, to filter out contaminants associated with an air stream entering the intake structure, and to prevent said screen from being drawn into the air intake opening.

• a screen including a flexible mesh material about which extends an outer perimeter edge, a plurality of perimeter defined apertures in said screen each further comprising a grommet;
• a plurality of fasteners mounted to locations associated with the air intake face surrounding the intake opening and which are engageable through said perimeter edge for securing said screen to the air intake face, said fasteners each further comprising an end post insertable through an aligning grommet in a first projecting position relative to the intake face and subsequently rotatable about an axis parallel to the air intake face to a crosswise extending position overlaying said grommets to retain said screen in place;
• and
• said perimeter edge being secured at specified locations in contact with the face of the air intake structure to prevent the admittance of air bypassing the air permeable material, to filter out contaminants associated with an air stream entering the intake structure, and to prevent said screen from being drawn into the air intake opening.

A filter screen assembly for use with an air intake structure, the structure including at least one face within which is formed an air intake opening, said filter screen assembly comprising:

• a screen comprising an air permeable material and having an outer perimeter edge;
• at least one elongated and interiorly channeled track secured to the face and proximate an extending edge of the air intake opening;
• and
• a plurality of trolley hooks supported by said track and engageable with edge locations associated with said screen in order to advance said screen across the air intake opening.
