VENTURI-CAGE ASSEMBLY

摘要

A skeletal support cage that supports a porous filter bag while it simultaneously provides an optimum spacing for a concentrically disposed aspirator that subjects the filter bag to a blast of cleansing air. The support cage is formed from a series of longitudinally extending spring members that include a "snap-in" detent locking the filter bag in an apertured tube sheet while also concentrically supporting a tubular aspirator within the filter bag to obtain optimum operation thereof.
