316L stainless steel fiber felt is sintered from multi-layer laid fiber - high porosity, high dirt capacity, repeatable back-flush and water-wash regeneration, 2-100 um rating - for polyester and chemical fiber polymer filtration, hot gas dedusting and catalyst recovery.
Stainless fibers of 2-40 um are laid into multi-layer felts with graded pore structure, then vacuum-sintered to bond fiber crossings. The media combines high porosity (70-90%) with high strength and far higher dirt capacity than woven mesh or sintered powder. It can be pleated into large-area cartridges or made into discs and plates.
316L stainless steel sintered fiber felt is made of micron-grade steel fiber (1.5-30 μm diameter), non-woven into webs, layered in pore-size gradient and sintered into a 3D porous structure. Porosity 68-85% gives high dirt-holding capacity and slow pressure rise; filtration rating 3-100 μm across ten models (BZ3D-BZ100D), bubble point 630-12300 Pa, permeability up to 1220 L/(min·dm2). More clogging-resistant than woven mesh and stronger with higher flow than powder sintered parts, it serves chemical fiber, hot-gas filtration, petrochemical and hydrogen applications.
For polyester and chemical fiber polymer filtration, steam and heat-transfer fluid filtration, catalyst recovery, fluidized bed distribution and coalescing separation. Cartridges, discs and custom assemblies available.
All data above are obtained under specific test conditions; the actual solution must be engineered to site conditions. AIFILTECH provides custom design and sizing based on actual gas volume, temperature, dust characteristics and emission limits.
