Baghouse Cleaning Methods

Baghouses come in 4 main design classifications based on "How the bags are cleaned" in other words, how the dust cake accumulation is removed and "managed".

Styles Method Airflow A/C Ratio
Pulse Jet System Uses high-pressure air directed down into the clean side of a filter bag in order to remove the dust cake from the surface of the media. This cleaning system can operate with airflow still going through the bag to the exhaust fan (on line cleaning). Generally, from 4-6 to 1.
Shaker Style System Physically shakes the bags in order to mechanically release the dust cake. The style of cleaning method requires the bag “module” or compartment to be isolated from the gas stream to the exhaust fan (off-line cleaning). Generally, from 2-4 to 1.
Reverse Air System Physically collapses the bags in order to mechanically “shear” the dust cake from the bag surface. Airflow: This style of cleaning method requires the bag “module” or compartment to be isolated from the gas stream to the exhaust fan (off-line cleaning). Generally, from 1-3 to 1.

Combinations and variations

  • Shaker with Reverse air assist: (off-line cleaning)
  • Traveling manifold reverse air: (on-line cleaning)
  • Plenum pulse: usually off-line
