You need a filter that can:
Withstand high temperature & high pressure without deformation · Maintain consistent filtration accuracy · Resist corrosion from aggressive chemicals · Operate in harsh or extreme industrial environments · Offer long service life and support repeated cleaning · Provide full customization to match your system
SINFT powder sintered filters are designed precisely for these needs.
SINFT powder sintered filters are precisely engineered to meet these exact requirements.

Broad material options — 316L, 304, 904L, 2205/2507, C276, Inconel 600, Monel 400, Ti, Ni — built for harsh chemicals and gas-liquid systems.


Multiple interface types including M20, M30, M36, threaded ends, flanges, and fully customized designs to fit any installation.
Perfect for fine chemicals, petrochemicals, gas purification, catalyst recovery, and other demanding applications.

At SINFT, every powder sintered filter undergoes strict quality control to ensure stable filtration accuracy and long-term reliability. Using professional equipment — including pore size testers, multi-pass benches, universal testing machines, and ultrasonic flaw detectors — we verify key parameters such as pore size, porosity, dirt-holding capacity, strength, airtightness, and sintering quality.
This comprehensive testing guarantees consistent performance in every product we deliver.

| Comparison Dimension | SINFT Powder Sintered Products | Common Market Products |
|---|---|---|
| Material Purity & Traceability | High-grade stainless steel / alloys with material certificates; fully traceable batches | Material sources unstable; often lack certificates |
| Pore Size Accuracy & Consistency | Maximum/mean pore size tested; uniform distribution | Large deviations; uneven pore channels |
| Mechanical Strength | High-strength structure verified by universal testing machine | Weak bonding → prone to cracking |
| Temperature Resistance | –200°C to 600°C stable performance | Limited heat resistance |
