Metallic fiber felt is made of metal fiber in
micrometer through lapping, laminating and high temperature sintering.
Multi-layer metallic fiber felt formed by layers of metallic fiber
with different pore sizes can achieve
high filtering accuracy and larger dirt holding capacity than single-layer felt. Metallic fiber
felt has uniform pore size distribution, high permeability and mechanical
strength. It is not only
resistant to corrosion and high temperature, but also can be welded, folded and reused. The metallic
felt is an ideal high efficiency filter media suitable for working at high temperature, high
differential pressure and high corrosion conditions.
Applications
Polymer filtering
Filtration in chemical and medical fields
Food and beverage filtering
Gas, water and printing ink filtering
Dust collecting for high temperature gas
Filtration in of oil refinery
Viscose rayon filtering
Pre-filtering in ultra-filter, protective
filter in vacuum pump
Support for gauze filter and carrier for
catalyst
Airbag in automobile
Fuel and hydraulic system filtering in
airplanes and ships
