Dust Collection Bags for Reverse Air Bag houses

Reverse air (R/A) bag-houses use continuous streams of low pressure air to remove collected solids. Bags are cleaned by back washing (reversing the air flow) within a chamber after shutting off the dirty gas flow and isolating the compartment. The recommended air to cloth ratio for these bag houses is between 1.75:1 and 2.5:1.


  • R/A bag houses are typically compartmentalized, allowing sections to be cleaned without shutting off the whole system.

  • Cleaning action is very gentle, which lengthens bag life.

  • Preferred for high temperatures due to gentle cleaning action.


  • Cleaning air must be filtered.

  • Provides no effective means for removing residual dust buildup.

  • Requires more maintenance than other types due to dust re-entrapment on the bags.
