Sintered metal fiber felt filter cartridges are made of random metal fiber felt, in cylindrical or pleated shape.

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.

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)

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 FeCrAl sintered metal fiber fleece for high temperature resistance are also available as request.

Typical applications of sintered metal fiber felt filter:

  • alternative to glass fiber filters for oil and fuel filtration
  • polymer melt filter and other high viscosity fluid filtration
  • high temperature gas / air dedusting or filtration

Bekaert  sintered metal fiber felt and top-rated made-in-China sintered metal fiber felt are available on request.
