What Are Sintered Stainless Steel Filters?
Sintered stainless steel filters are porous sintered steel elements. It mainly has two types of materials: SS304 and SS316. It is the most essential component of your filtration system, providing you with long-term effective filtration effects and stable production processes. You can use it to process high-temperature and high-pressure filtration processes in petrochemical, pharmaceutical, food and beverage, gas-liquid separation.
Classification Of Sintered Stainless Steel Filters
FiltEdge can provide you with over 100 types of sintered stainless steel filters, including different filter cartridges, seamless filter tubes, multi-layer mesh, and filters, perfectly matching your filter housing.
Made of high-quality 316L stainless steel sintered, it is sturdy and durable, and can be repeatedly rinsed and reused to reduce consumable costs.
Equipped with standardized interfaces such as NPT thread and 222/226 double opening (DOE), it can replace mainstream brands’ filters such as Parker and Mott.
By stacking and firing multiple layers of woven stainless steel mesh with different thicknesses, it not only has a good flow rate but also can deal with high viscosity media.
Adopting micrometer sized metal fibers for non directional paving and sintering, it has an ultra-high porosity and pollutant holding capacity of about 80%.
Using spherical or irregular stainless steel powder for molding and sintering, the accuracy can reach 0.2-20 microns, and the interception efficiency is extremely high.
Precision cut disc-shaped sintered components, including single-layer powder, multi-layer mesh, or composite structures, are used in filter presses, laboratory filtration devices, and valve protection ends.
Customized length, diameter, and wall thickness for high flow gases or liquids.
Flat large-area sintered plates can be cut and welded as needed.
