Sintered metal fiber felt filter cartridgesAdmin2023-12-12T09:42:45+08:00
Sintered metal fiber felt filter cartridges are made of random metal fiber felt, in cylindrical or pleated shape.
Cylindrical sintered metal fiber felt filter cartridge
Cylindrical sintered metal fiber cartridges are butt or joint welded at the connection area. The sintered metal fiber felt for cylindrical type is often metal fiber felt with wire mesh on one side or both sides.

Pleated sintered metal fiber felt filter cartridge
For pleated sintered metal fiber cartridges, the metal fiber felt is usually wrapped with square weave mesh on both sides to protect the felt. On the outside of the pleats, there is possibly perforated metal sleeve to protect the pleats, or it may left naked if there is no backwash or backpressure working condition.

Outstanding features of the sintered metal fiber felt:
extreme high porosity (up to 80%)
multi layers 3D structure
in-depth filtration property
excellent resistance to temperature ( higher than 1000℃ as for FeCrAl fiber)
higher strength and ESD free comparing to glass fiber & other non-metallic filter media
Specification of sintered metal fiber felt:
Absolute Rating μm
Bubble Point Pressure Pa
Average Air Permeability
Dirt Holding Capacity mg/cm2
Sintered metal fiber felt specification datasheet
Specifications are based on Bekaert Bekipor AL3 metal fiber porous filter media. Other type of sintered metal fiber felt, like Bekipor BL3 CL3 CL4, is also available as required.

Sintered metal fiber felt – random laid metal fiber
The sintered metal fiber felt filter cartridges allow high flow rates while keeping excellent dirty holding capacity. Thanks to its porous structure, it is easy to be cleaned by backwashing.
Standard material for sintered metal fiber is 316L stainless steel. However, Hastelloy sintered metal fiber for high corrosion resistance and Inconel, FeCrAl sintered metal fiber fleece for high temperature resistance are also available as request.
Sintered metal fiber felt with protection mesh for tougher working conditions
Protection mesh can be sintered together with the ordinary sintered metal fiber felt to give extra support and higher strength. The protection mesh can be on the bottom side to give support, or the mesh can be on both sides to provide support and protection for cylindrical filter elements.
