The 304 stainless steel sintered mesh filter cartridge is made by stacking five layers of stainless steel wire mesh in a specific sequence, then sintering them in a vacuum to form a standard-structure filter medium. The typical five-layer structure includes a framework layer, control filtration layer, dispersion layer, protection layer, and supporting framework layer, offering high mechanical strength, good air permeability, and stable separation performance. It is suitable for harsh conditions involving high temperature, high pressure, and strong corrosion, especially for high-temperature gas filtration, and can be customized in various shapes, precision levels, and connection types.
