Sany stainless steel sintered metal fiber felt is made of extremely fine steel fiber (micron grade) by sintering in high temperature after special non-woven matching and laying with the pore gradient formed by layers of different pore sizes.The stainless steel sintered fiber felt product can achieve higher rating and larger holding capacity,and larger filter area,and can keep the filtering working continuously.
Sany sintered non-woven fiber felt structure
There are two types of Sany sintered non-woven fiber felt, the conventional sintered fiber felt and the sintered fiber felt with protective mesh. The second type is added a layer of wire mesh(it may be on a side or on the interlayer ) on the conventional sintered fiber felt, or a layer of wire mesh on each side.Then sintering together forms a high strength sintered fiber felt.

Compare with other filtering media
Sany sintered non-woven fiber felt can overcome the disadvantages of easy to be blocked and damaged of stainless steel mesh, and the disadvantages of fragile and low flow rate of sintered stainless steel powder filter,and has the advantages of resistant to high temperature and high pressure, of which normal filter paper and glass fiber can’t compare with.
