Shaker - Mechanical Shaker Bag Houses

Shaker bag houses use mechanical shaking or vibrating actions to dislodge the filter cake. Bag bottoms are secured to a plate and their tops are connected to horizontal beams. These beams, driven manually or by a motor, vibrate to produce waves in the bags which shake off particulate matter. The recommended air to cloth ratio for these bag houses is between 2.0:1 and 2.5:1.


  • Design and operation simplicity.

  • Can be compartmentalized to allow sections to be cleaned without shutting off the whole system.


  • Cannot operate in high temperatures.

  • More energy and time intensive than other cleaning methods.

  • Small amounts of positive pressure inside the bag can significantly reduce collection efficiency.

  • Large footprint and space requirements, and requires a large number of bags.
