Depth filtration vs Surface filtration.

For most baghouse operations this filter distinction applies to the initial dust layer.

Understanding what filter distinction your baghouse was designed for is important due to this being the only filtration happening after a new filter install or after a pulse cleaning cycle.

Once a layer of dust has developed into a cake this cake becomes the primary means of filtration.

The desired filtration approach also needs to be in line with the filter regeneration setup.

Filters using the mechanisms of straining and impingement for surface particle retainment profit from the regeneration pulse energy tuned to blocking vacuum pressure and fabic acceleration.

Filters using the mechanism of entanglement benefit more from tuning the cleaning energy to maximize the cleaning air permeating through the filter in the opposing direction of normal flow.
