Filter Bag Flow Rates

Comparison of Filter Bag Models by Size and Flow Rate Capacity

 

The maximum flow rate through a filter bag is determined by the resistance to flow, indicated by its initial differential pressure when it is clean.  As the filter bag deisgn becomes more complex with thicker materials and multiple layers the maximum flow rate is reduced.  In the chart below the #2 size standard efficiency needle felt filter bags have a maximum capaicty of 176 GPM where as the same size ACCUGAF filter bag has a maximum flow rate of 66 GPM and that is because the ACCUGAF filter bag is fabricated from thicker, denser material and has multiple layers - a requirement to provide 99.9% efficiency.

 

The industry standard size filer bags are numbered 1 - 4.  The "SE, 152, 154 and Certa-Seal" filter bags are for obselete Ronningen-Petter bag filer housings, however the filter bags themselves are still available.
