Desceiption
Sintered metal filter cartridge, is made of stainless steel woven wire mesh, or stainless steel fiber felt. It is constructed by using multi-layered wire mesh overlapped and then sintered together in vacuum furnace, rolled into a cylinder shape with two ends welded together. Rolling seam welding process is added for roundness and flatness of entire structure. Its interlaced mesh forms a rigid structure which overcomes the disadvantages of ordinary wire mesh, such as low strength, unstable hole shapes, also beats sintered powder filter, ceramic filters, etc. Above all, this stainless steel filter cartridge wins great favor with prominent features like high temperature resistance, smooth wire pores, good permeability, high dirt holding capacity, in many industries such as food, environmental protection, chemical, aerospace.

Properties for sintered wire mesh with different layers
SMFB-2 Single layer sintered mesh filter
Single layer sintered mesh:
Sintered woven wire mesh filter is closely bonded together by diffusion leading to permanent geometry, pore size and filter rating.
Features: one-layer stainless steel woven wire mesh is an alternative for low-cost mesh filter and doesn't require sealing methods according to its construction. Common shapes are round disk, ring and simple cylinder.
SMFB-3 3-layer light-duty sintered mesh construction
2-3 Layers Sintered mesh
Sintered dutch woven wire mesh has good mechanical strength and medium aperture. The filtration layer with desired aperture is sandwiched between outer & inner protection layers.
Features: ideal for manufacturing pleated cylinder filter or candle filter and sintered discs.
SMFB-4 5-layer sintered mesh construction
5-layer sintered wire mesh
A single layer of fine woven wire mesh which decides the filtration is placed between two protective layers of coarser woven wire mesh, and then these three-layer wire meshes will be sintered together with two support-layers to improve the stability.
Features: 5-layer sintered wire mesh laminates has extensive fields in chemical processing, food & beverage, pharmaceuticals and transportation. It is used in liquid & gas filtration, fluidized beds and others.
SMFB-5 Perforated sintered mesh
6-layer sintered wire mesh
6-layer sintered wire mesh laminates has an additional drainage player compared with 5-layer mesh.
Features: improves the quantity of the filter capacity.
