Sintered Metal Fiber Felt with Porous Construction for Gas Filter
Sintered metal fiber felt is produced in a vacuum furnace, with metal fibers randomly laid. We select the fiber diameters and basis weight precisely, then control the pore diameter through thickness. The sintered metal fiber felt keeps a three-dimensional reticulated porous structure with high permeability, low-pressure drop, and excellent dirt holding capacity. The bigger particle could be captured at the outside surface, and small particles pass through the sintered metal fiber felt.
The metal fiber felt is usually sintered together with metal wire mesh to enhance the strength and subsequent longer on-stream life. Sintered metal fiber felt could be cleaned in sit and minimized the shutdown time, saving cost.
The usual available material is stainless steel 304, 316L, Hastelloy, Inconel, FeCrAl, etc. The sintered metal fiber felt is mainly used for gas filter and polymer filter. We have rich experience and could help suggest the most siutable material. If you have questions on choosing sitnered metal fiber felt, pls contact us.
