1um Outer-thread Connector SS316L Porous Filter Element Muffler

TOPTITECH's 1um Outer-thread Connector SS316L Porous Filter Element Muffler utilizes gas-atomized 316L stainless steel powder with controlled particle size distribution for uniform porosity. The sintered matrix achieves precise 1-micron absolute filtration through optimized compaction pressure and hydrogen atmosphere sintering, ensuring consistent pore structure with high mechanical strength and corrosion resistance. The outer-thread design enables direct integration into hydraulic/pneumatic systems without additional adapters, while the muffler function dampens pulsation through tortuous porous pathways.

This filter element undergoes post-sintering electrolytic polishing to enhance surface cleanliness and reduce particulate shedding. The austenitic SS316L microstructure provides pitting resistance in chloride environments, validated by ASTM A262 Practice E testing. Applications include high-purity gas filtration, pharmaceutical process equipment, and semiconductor manufacturing where metallic filters outperform polymer alternatives in high-temperature sterilization cycles. The monolithic sintered construction eliminates delamination risks associated with layered designs.

Products Features

 

 

Precision Filtration Performance‌

Gas-atomized 316L powder achieves consistent 1-micron absolute rating through controlled sintering parameters, eliminating bypass risks common in wound fiber filters.

Structural Integrity‌

Monolithic sintered construction prevents delamination under pulsating flows, outperforming layered mesh or laminated designs in shock resistance.

Corrosion Resistance‌

Austenitic SS316L matrix with electrolytic polishing passes ASTM A262 Practice E testing, ensuring pitting resistance in chloride-rich environments.

Process Integration‌

Outer-thread connection eliminates adapter requirements, reducing potential leak points in hydraulic/pneumatic systems while maintaining ASME BPE-compliant surface finishes.

 

 

Multi-Functional Design‌

Tortuous porosity not only filters particulates but also attenuates pressure pulsations, serving as integrated muffler without flow restriction penalties.

High-Temperature Stability‌

Solid-phase sintered structure maintains pore integrity during autoclave sterilization cycles where polymer membranes degrade.

Cleanability‌

Backflush-compatible architecture with ultrasonic-cleaning-friendly surface morphology minimizes particulate retention.

 applications
