ACCUGAF Series Filter Bags have an all-welded, multi-pleated construction that increases the surface area of the bag as compared to standard filter bags. This construction also results in high efficiencies and long service life. The bags have a pleated pre-filtration layer and a complex design of final filtration layers. This permits the removal of difficult-to-filter gels and deformable particles with a high capacity of solids loading. An outer web covering eliminates any downstream fiber migration contamination. Four different models provide filtration efficiencies ranging from 95 to 99 percent.
