1.Metal Fiber Sintered Felt

 

Metal Fiber Sintered Felt is made of non-woven metal fibers, which are laminated and sintered together£¨generally SUS316L£©. The Sintered Felt has excellent durability, corrosion and abrasion resistance and is a kind of deep-filtering, which has advantages of excellent filtering result, low filtering resistance and high dirt holding capability. Sintered felt is mostly used in polymer and gas industries, which has high temperature/pressure processions. The excellent filtering capability largely improves product quality, reduces production cost and extends life span of facilities.

Remarks

Above data refers to Bekaert AL3 series sintered felt;

- Bubbling pressure test meets Standard ISO 4003;

- Average air permeability test meets Standard ISO 4022,

- Dirt holding capacity test meets Standard ISO 4572, and final pressure drop is 8 times of initial pressure drop.

2. Multi-Layer sintered mesh

Filtering meshes with different filtering properties are sintered into metal mesh, which is mainly used for high temperature/pressure media filtration. Metal meshes with different wire diameter and mesh are sintered together in order under high temperature in vacuum condition. During utilization, each layer of mesh are not separated and connective is excellent, so it doesn¡¯t need to replace frequently.

3. Wire mesh filter

Filtering meshes with different filtering properties are laminated together without sinter, and in this series, Pleated filter has better strength, not easy falling off, easy cleaning, high temperature resistance and low cost etc.

 

4. Metal powder for filter

The products are made from metal powder. (Generally, the powder is sphericity or subsphaeroidal shape) compacting¡ªsintering¡ªfinishing operation. Metal powder can be copper and stainless steel, or nickel and titanium. The product has such characteristics as accurate pores (99.8%), easy to cut and weld, high temperature resistance and have different corrosion resistance with the variation of material.
