Stainless Steel Powder Sintered Filter Cartridge
A stainless steel sintered powder filter is made by pressing and vaccum sintering stainless steel powder (typically 304, 316, or 316L) below its melting point. Fine stainless steel particles are sintered at high temperature to create a strong and porous filtration medium. This process formed a rigid, interconnected pore structure, so Huahang metal powder sintered filter has uniform pore distribuition, high mechanical strength, and controlled filtration accuracy.
Unlike sintered wire mesh filters, porous powder sintered filters provide true depth, capturing particles throughout the structure rather than only on the surface. And the raw powder material can be upgrade to titanium powder or copper powder to adapt defferent applications. For highly corrosive or high-purity applications, consider titanium sintered filters. Sparger sintered filter elements are widely used in industries requiring high precision, high temperature resistance, corrosion resistance, and reusable filtration systems, such as chemical processing, petrochemical, pharmaceutical, and gas purification.

Working Principle
Huahang metal porous powder filter works through a three-dimensional interconnected pore network:
- Fluid enters porous structure
- Particles are trapped inside pores (depth filtration)
- Clean fluid exits
The porous powder deep filtration mechanisms include:
- Mechanical interception
- Diffusion
- Impaction
