Dealing with Shortened ACA Series Filter Bag Life
If ACA filter bags wear our rapidly, refer to the following list to diagnose certain difficulties:
Chemical Attack
Filter bag material may degrade from certain chemicals in the dust of the air stream.
Moisture
Filter bag material may shrink or degrade from excessive moisture in the filter chamber.
Abrasion
If filter bags are improperly installed, bags can rub together or against filter chamber walls,
resulting in excessive wear. Abrasion on the filter bags near the air inlet area indicates that a
dust-impingement baffle may be required.
High Temperature
If operating temperatures are above the recommended limit for filter bag material, damage
may result.
Consult the Service Department for assistance if difficulties occur.
