Sintered fiber media

Metal fiber fleeces are laid, sintered, and calendered from different fiber layers with stainless steel fibers from 2 μm diameter. The result is a filter media that is easy to process and made of corrosion-& heat-resistant, and stable stainless steel material with precise filtration performance. We can design metal fiber fleece so that filter fineness, porosity, dirt-holding capacity, and stability meet the requirements.

Sintered fiber media is widely used in burner applications, but many other industries also take advantage of its excellent filtration performance.

Excellent filtration characteristics

Our sintered fiber media achieves superior filtration efficiency by combining exceptional dirt-holding capacity with excellent flow properties. The precise selection of fiber diameters and basis weight are the key factors the success.

The structure of the stainless steel fiber felt is designed to control the pore diameter throughout the thickness. The result is a graded pore matrix. This allows our nonwoven fiber to trap the larger particles in the outer layers, while smaller particles can penetrate deeper into the matrix.

As a result, our sintered fiber media achieve a higher dirt-holding capacity and a longer service life in operation. Our metal fiber media can also be configured as a surface filter to trap particles on the outer layer when you want backflush applications.
