ABSTRACT:
A filter screen assembly for use with an air intake structure, the structure including a face within which is formed an air intake opening. The filter screen assembly includes a screen having a flexible mesh material and an outer perimeter edge. A three-dimensional component, including such as a multi-sided frame or a plurality of spacer collars, are secured to the face of the intake structure surrounding the opening. The screen is secured about locations associated with its outer perimeter to the face of the air intake structure to space the screen from a surface of the air intake structure and in order to filter out contaminants associated with an air stream entering the intake structure. Spacing the screen also prevents objects impacting the screen from damaging such as the surface coils associated with the air intake opening.
