Sintered Metal Fiber Felt

Sintered Metal Fiber Felt

Sinter metal fiber felt filter is made of overseas stainless steel fiber as raw material, and it is a high porosity porous deep filtration material with process of non-spinning, folding of the metal fiber.

Sintered metal fiber felt Cartridge (XKF) original uses imported stainless steel fiber as raw material. After non-woven laying and lamination of metal fiber, it is made into porous deep filter material by high-temperature vacuum sintering. Its most prominent feature is high porosity. Since the diameter of the metal fiber is very uniform, the pore size distribution is limited to a very narrow range, and the metal fiber felt provides good gas permeability while ensuring filtration precision. The metal fibers also increase the filtration area by folding, thereby increasing the amount of filter dirt.

Product Features and Benefits

Depth filtration and high retention
The structure of sintered fiber felt forms a gradual pore size gradient, realizing deep capture of small particles, and the filtration efficiency is as high as 99.9%, which is a real stainless steel sintered fiber filter.

Large specific surface area and low pressure drop
The felt-like fiber network provides a large specific surface area, keeping the pressure drop at the lowest level while maintaining high throughput, thus reducing energy consumption.

Excellent Mechanical Strength
The metal fibers have outstanding strength after sintering and can withstand multiple pulse washing and backwashing, with a service life far exceeding that of traditional membranes and ceramic cartridges.

High Temperature and Chemical Resistance


The 316L material is stable at 550°C and in strong acid and alkali environments, making it suitable for demanding chemical and high temperature gas filtration applications.

Washable and renewable
Supports high-pressure water, steam, chemical solvent or ultrasonic cleaning, with rapid performance recovery after cleaning, significantly reducing long-term operating costs.

FAQ

Determined by media particle size and downstream equipment requirements, generally 0.5–1 µm is used for high-precision filtration, and 3–5 µm is suitable for pre-filtration; LiandaFiltration can provide process selection guidance.

Standard 304/316L sintered metal fibers can withstand temperatures ≤550°C, but the pulse pressure should not exceed 4 bar to avoid fiber fatigue fracture.

The fiber felt has a more continuous pore structure, higher dust holding capacity, and more obvious gradient filtration, making it suitable for working conditions with high dust content, high temperature, or oil mist.

Yes. LiandaFiltration can customize the outer diameter, length, fiber diameter and material (such as Inconel, Hastelloy) according to customer needs to meet special working conditions.
