FMS filter bag is a highly efficient high temperature resistant, corrosion resistant, acid and alkali resistant, wear resistant composite product. Flumes is a new high-temperature filter material developed for dry dust removal of blast furnace gas.

The Flumes filter bag adds P84 fiber to the fiberglass needle felt, which makes the felt layer tighter and the entanglement between the fibers is enhanced, which can cope with higher filtration wind speed.

P84 fiber has a trilobal cross section, which forms a high surface area coefficient, which increases the dust collector rate. Moreover, the special cross-sectional shape of the fiber makes the dust mostly concentrated on the surface of the filter material, which is difficult to penetrate into the filter material. The gap reduces the running resistance and thus increases the filtering wind speed.
