Title: Filter bag cage

Abstract: A filter that is used to remove dust or other particulate matter from a carrier gas being directed therethrough. The filter comprises a cylindrical bag supported on a skeletal cage that may be shipped in an unassembled form and expanded to final configuration only when prepared for use. The arrangement permits shipping and storing the filter bag in a "knock-down" form that occupies but a small fraction of its final volume, while it may be readily assembled and held permanently rigid by an integral tension spring.
