Sintered Metal Fiber Filter Media and Cartridge for High-Flow Gas and Liquid Filtration

Sintered Metal Fiber Filter

CMI Sintered Metal Fiber Filters are high-performance filtration media engineered for applications requiring maximum permeability and minimal pressure drop. Manufactured by layering non-woven metal fibers and bonding them through high-temperature vacuum sintering, these filters form a highly porous and uniform structure with a narrow pore size distribution.

Compared to sintered powder or mesh, this metal fiber media provides significantly higher porosity and flow capability, making it exceptionally effective for high-velocity gas filtration and high-viscosity fluid processing. Available in versatile forms—including pleated cartridges, discs, and tubes—and primarily crafted from 316L stainless steel, CMI fiber filters offer excellent dirt-holding capacity and thermal stability. They are fully cleanable and robust enough for demanding industrial tasks such as catalyst recovery, chemical fiber filtration, and high-temperature transpiration cooling.

High-Porosity Filtration Media for High Flow and Low Pressure Drop Applications
CMI sintered metal fiber filters are manufactured by layering non-woven metal fibers and bonding them through high-temperature vacuum sintering, forming a highly porous and uniform filtration structure.

This structure provides extremely high porosity, narrow pore size distribution, and stable performance under high temperature and pressure conditions.

Compared with powder and mesh structures, sintered metal fiber media offers significantly higher permeability and lower pressure drop, making it especially suitable for high flow and gas filtration applications.

The material can be fabricated into cartridges, discs, sheets, plates, tubes, and pleated elements, allowing flexible design for a wide range of liquid and gas filtration systems.
