Metallic fibre felt

Metallic Fiber Felt is made of metal fiber in micrometer through lapping, laminate, and high-temperature sintering. Multi-player metallic fiber felt which has pore diameter grads formed by layers of different pore size can achieve high filtering accuracy and larger dirt holding capacity than single layer Felt. Metallic Fiber Felt has uniform pore size, high permeability, and mechanical intension. 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 efficient filter media suitable for working at high temperatures, high differential pressure, and high corrosion atmosphere.

Characteristics of Metallic Fiber Felt

High porosity

High dirt holding capacity (for in-depth filtration), Long on-stream life-time, High flow rates : up to 20 times higher versus other media, +Low pressure drop (lower energy cost)

Thin membrane

Cleanable, superior backwash and back pulse capabilities, Easy to pleat and weld.

Stainless steel and other alloys available

Heat and corrosion resistant (dep. on alloy). Not brittle, Chemical cleaning possible, Weldable, Low thermal expansion and no thermal shock.
