Dust Collector Bags

Shaker bags are used in an older concept dust collector design which goes back several decades before the introduction of pulse jets. In the shaker concept, the filter bag collects dust on the inside surface. The typical shaker collector is compartmentalized so that a single compartment can be taken off-line for cleaning. After closing the dampers, the bags in the off-line compartment are mechanically shaken by the bag hanging system in the top of the compartment. In all cases, the bag is physically agitated in order to dislodge the dust. As the filter bags are shaken down, the dust drops down into the hopper below to be removed by airlock, screw conveyer or slide gate.
