Name: 5um SS316L Special-shaped Porous Filter Disc For Precision Equipment
Brand: TOPTITECH
SKU: 269610619

Engineered for critical filtration applications, TOPTITECH's custom-shaped sintered 316L stainless steel filter disc features a trapezoidal geometry with precision-edge polishing, ensuring seamless integration into high-performance systems. The powder metallurgy manufacturing process achieves a controlled 5μm&10um pore structure with uniform permeability, optimized for particle retention in pharmaceutical, semiconductor, or aerospace fluid handling. Hydrogen-sintered 316L material delivers exceptional corrosion resistance against acids, alkalis, and sterilization protocols, while the graded porosity design enhances dirt-holding capacity without compromising flow rates.

5um SS316L Special-shaped Porous Filter Disc for Precision Equipment 4

Each disc, which is specially made in accordance with CAD specifications, is tested for bubble-point integrity and electrochemical passivation. The trapezoidal profile reduces dead zones in compact assemblies, with laser-cut edges meeting surface finish standards. Ideal for CIP/SIP processes, these discs maintain structural stability across -200°C to 600°C thermal cycles, outperforming polymer membranes in longevity. Optional multi-layer sintering is available for gradient filtration needs in catalyst recovery or nanobubble generation systems.
