FeCrAl Sintered Fiber Felt With 3D Mesh Porous Structure

FeCrAl sintered fiber felt is a multilayer metal felt made of micron metal fibers sintered at high temperatures, whose different pore size layers form a pore gradient, thus achieving extremely high filtration accuracy and greater dirt holding capacity than the single-layer fiber felt. The material features three-dimensional mesh, porous structure, high porosity, large surface area, uniform distribution of pore size, etc., which can continuously maintain the filtering effect of the filter cloth. Compared with metal mesh, which is easy to block and damage, powder filtration products that are easy to break and have a small flow rate, and filter paper and filter cloth that are not resistant to temperature and pressure and other defects. FeCrAl sintered fiber felt has excellent filtration performance, high temperature resistance performance, corrosion resistance performance, high precision, and it is an ideal filtration material.

Multiple FeCrAl sintered fiber felts each with 2 holes of different sizes
