Valuable, practical knowledge results from Neundorfer bag testing consulting services that assess the condition of baghouse/fabric filter bags quickly and at about 1/3 the cost of other bag tests. Regardless of how well a baghouse is operated or maintained, there is a progressive reduction in air flow permeability during the normal life of a fabric filter bag that causes increased baghouse pressure drop and required cleaning frequency. This regression in air flow (or blinding) is the primary reason that fabric filter bags are replaced. By performing regular bag testing and plotting results, Neundorfer can predict remaining bag life based on the reduction in permeability, to assist with:
- Scheduling/planning bag replacements
- Avoiding increased costs related to emergency bag procurement
- Process curtailments and/or shutdowns
- Confirmation of maximum filter bag life
- Energy optimization for cleaning
