An extensive study has now compared the performance of multi-layered constructions of these media in terms of filtration efficiency, pressure drop and cleanability. One special focus of the study was a comparison of the combination of nonwovens and stainless steel meshes as opposed to multi-layered constructions made exclusively of woven metal meshes. The study showed that in both variants, an upstream filter using Optimized Dutch Weave (ODW) made by GKD – Gebr. Kufferath AG was particularly efficient. Combinations with this woven mesh type significantly increased the service life of the filter media in hot gas filtration.
