SFFILTECH’s Steven Zhai Contributes Filter Bag Cleaning Article to AFS
SFFILTECH is pleased to share a new technical contribution by Steven Zhai, Founder & Brand Director of FiltEdge LLC and SFFILTECH. His article, When Pulse Jet Cleaning Leaves Dust on Filter Bags, was published on the American Filtration and Separations Society (AFS) website on October 5, 2026.
The article brings together filter-bag and operating-system considerations for a familiar maintenance question: what does remaining dust after pulse-jet cleaning actually tell us?
Its discussion connects cleaning performance with operating measurements, pulse-air delivery, dust and moisture conditions, and the construction of the filter medium. For readers working with needle-felt or PTFE membrane bags, it encourages evaluating the system and the media together.
Sharing this experience supports SFFILTECH’s ongoing technical dialogue with customers and filtration professionals. The complete article, with Steven’s author information, is available from AFS.
