Sintered Fiber Felt with High Porosity and Excellent Permeability

Two pieces of square sintered fiber felts with different sides.

High porosity and excellent permeability always satisfy our customers for filtering industries.

Sintered fiber felt, mainly made of stainless steel, is produced by lapping, laminating and high temperature sintering. Compared with woven wire cloth, sintered fiber felt has better filtration function, because it has high porosity, excellent permeability, dirt holding capacity and filtering accuracy. With high strength and long service life, it is widely added into various sintered wire mesh products for a filtering layer, it also can be sintered with multiple fiber felts to form filter media.

Feature

High dirt holding capacity, filtering accuracy.
High porosity and excellent permeability.
Low pressure loss and large flow.
High heat and corrosion resistance.
Easy cleaning and long service life.
