Filter bags for Reverse Air or Shaker designs
In baghouses using reverse air or shaker cleaning systems, particles are collected on the inside surface of the bag. The dust laden gas enters through the dirty side (inlet) of the collector and flows up through the bag. The particles are filtered by the dustcake and the fabric, and clean air exits through the outside of the bag.

Anti-Collapse Rings are metal rings of various wire gauges, metals, and platings sewn to the outside of the bag body to prevent the bag from collapsing during cleaning.
