Dust particles are collected on the inside surface of the filter bags in a shaker style  baghouses. The dust-laden gas enters through the dirty side (inlet) of the dust 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. A shaker baghouse utilizes an electric motor driven mechanical system to clean the filter bags by shaking them after dust particles are collected and accumulated on the inside surface of  the filter bags.
