Five wire layers fused into one sheet: multi-layer sintered mesh is made by stacking woven stainless steel screens and vacuum sintering them together, so the pores interlock and the layers never separate. Filtration rating 1-200μm, uniform and stable, far stronger than single screen — ready for stamping, welding and cartridge conversion, cut to drawing within 1500×1200mm.
Multi-layer sintered mesh is built from several woven wire layers pressed and vacuum-sintered into a single rigid sheet. The interlocking pores form a uniform filter structure without the weakness of plain woven screen: low strength, poor rigidity and unstable pore shape. Porosity, permeability and strength can be matched to the duty, giving balanced filtration rating, pressure drop, mechanical strength and heat resistance.
The standard five-layer build places a protection layer, a filtration layer, a separation layer and support layers in one laminate: the filtration layer sets the rating, the outer layers take wear and pressure, and the separation layer keeps the flow paths open. The result combines stable accuracy with high strength, and works continuously under pressure.

Up to 高温高压工况 in Stainless steel·Ti·Ni·Cu. Near the ceiling, oxygen and velocity matter as much as temperature — reading one figure alone leads to the wrong grade.
Adjustable within 1-200μm. Finer rating costs flux, so the practical route is to work back from the allowed pressure drop.
We do — a drawing or a sample is enough to start, with tolerances agreed before quoting.
stock items go out same day, non-standard follows the production schedule.
Samples are quoted as a small batch and credited against the volume order, per the quotation.
All data above are obtained under specific test conditions; the actual solution must be engineered to site conditions. AIFILTECH provides custom design and sizing based on actual gas volume, temperature, dust characteristics and emission limits.
