FLOW STRAIGHTENER ARRANGEMENT FOR USE WITH AIR CLEANER ASSEMBLIES; METHODS OF ASSEMBLY AND USE; AND, AIR CLEANER ASSEMBLIES WITH FLOW STRAIGHTENER ARRANGEMENT

摘要

A flow straightener arrangement usable with an air cleaner assembly is described. The flow straightener, generally, comprises first and second permeable screen sections, spaced from one another. The screen sections can comprise portions of woven wire screen pieces. In an example depicted, one of the screen pieces is configured in a bowl-shape and the other is a flat piece positioned in extension across the bowl-shaped first piece to form the flow straightener. Methods of assembly and use are described, as well as systems having the flow straightener positioned therein.
