Baghouse Misconceptions

Misconceptions About Baghouses

Several key misconceptions about baghouses tend to crop up.

Myth 1: Bags Do the Filter

It’s actually the control dust layer that does the filtering. This raises the importance of good start-up practice so that the bags are not blinded and a control layer is able to form. The first 24 “ 36 hours are most critical in a new bag’s life.

Myth 2: Clean Bags Are the Key to Efficient Baghouse Operation

Excessive cleaning knocks off the filtering control layer, leaving the bag media exposed and accelerating bag wear.

Myth 3: Filtering Wears Out Bags

The dominant factor in bag wear is cleaning energy.
