FILTER BAG FAILURE ANALYSIS

Treat the cause NOT the symptom

Filter bags fail if any of the primary functions of the bag requirements yield unsatisfactory performances:

Filterability, Cleanability, Durability

Unlike most textiles, filter bags are in use until effective performance ends. If premature failure occurs, the results often are: Throwing away 30 feet of good bag for 2 feet of failed bag. Increased maintenance costs for bag installation/removal. Production slowdown or shutdown. Bag replacement expense.

Baghouses contain only two basic performance measurements: pressure differential and stack opacity. These instruments report only the symptoms of faulty performance – they do not determine the causes.

Reacting to these symptoms without knowing the cause can further aggravate the problem and even render the bags incapable of satisfactory performance.

E.C.C. Laboratories incorporates state of the art testing equipment and unparalleled personnel expertise for complete testing and evaluation of filter bags, addressing all causes for failure.

Thorough reports generated from bag testing include microscopic photography, supporting data, chemical analysis and particle size evaluations as appropriate to the cause of failure. Conclusions and appropriate operator corrective actions are based on scientific facts.

Included with each report is a DATA PAGE on each bag tested. Click HERE to see a sample.

Symptom: High Baghouse Pressure Differential Possible causes: Bags not properly cleaning due to gas stream moisture Compartment not isolating preventing cleaning Faulty pressure gauges Cleaning mechanism not functioning Higher dust loading Bag seal leaking, causing reverse blinding Higher air flows Bags plugged/Surface restrictions Bags blinded/Internal dust in depth Improper filter media selection
