Fabric Filter Bag Testing

Fabric Filter Bag Testing

Our fabric laboratory is the only independent facility in North America that is equipped with a test apparatus which complies with internationally recognized test standards (ASTM D6830-02 & VDI/DIN Standard 3926), based on the German VDI method 3926, and allows the user to measure baghouse filter media performance under defined conditions with regard to the fabric filtration velocity (G/C), particle size distribution, and cleaning requirements.

The fabric lab is also equipped to measure tensile strength, mullen burst strength, and flex strength, and can conduct particle size analysis, microscopic analysis, fabric permeability analysis, and chemical analysis. To more closely simulate actual operating conditions, ETS has modified a standard Frazier permeability apparatus to allow fabric filter bags to be tested non-destructively at elevated temperatures and pressure drops.

The test data are reviewed and interpreted by skilled staff, including some of the nation's most noted baghouse consultants. The data are reviewed by a committee approach, with each member offering various perspectives and unique insight as to the cause of fabric filter bag failure and potential remedies. A report is prepared for each project, including test data, analytical results, photographs, and recommendations/conclusions. For used fabric filter bag troubleshooting projects, proper solution to the root cause of the problem can often be recommended from review of the project results, ETS's filter bag testing database, and the client's baghouse operating characteristics.
