Reverse Air Filter Bags

Particulate is collected on the inside surface of the bag in baghouses using reverse air cleaning systems. The dust-laden gas enters through the dirty side (inlet) of the collector and flows up through the bag. The particulate is filtered by the dustcake and the fabric, and clean air exits through the outside of the bag. The steel bottom of the bag protects the filter bag from collapsing. Reverse air bag top and bottom designs vary by cleaning system and original equipment manufacturer (OEM).
