Sintered Metallic Fiber Felt Laminates

The Sintered Metal Fiber Felt series of metal filtration products provide the ability to achieve high filtration efficiencies from a combination of depth and tortuosity while at the same time providing exceptional dirt holding capacity and flow characteristics.

Filter efficiency is achieved by the precise selection of fiber diameters and basis weight. The medium’s matrix is constructed to control the pore diameter throughout its thickness, allowing us to achieve a graded pore structure that captures the desired larger particles on the outer layers while allowing smaller particles to penetrate deeper into the medium matrix.

The result is higher dirt-holding capacity and subsequent longer on-stream life. The media filter can also be configured as a surface metal filter to trap particles on the outer layer if you desire backflush or back pulse regeneration applications.

Metal fiber felt can be bonded together and can also be bonded to woven wire support mesh for added strength and flexibility.
