Constructed from 304/316L stainless steel with PP/PTFE/stainless steel pleated cartridges, this system achieves pressure drops ≤70Pa, reducing system energy consumption by 15%-25%. The filter body operates at temperatures up to 200℃, with PTFE cartridges rated to 250℃.
Stainless Steel Sterile Filters: Manufactured from food-grade 304/316L stainless steel with surface polish to Ra≤0.8μm, meeting GMP and FDA standards. Equipped with 0.22μm/0.45μm filtration precision options, these units achieve 99.999% sterilization rates while withstanding working pressures of 1.0-1.6MPa and temperatures from -10℃ to 120℃.
High-Pressure Filter Systems: Engineered for working pressures up to 30/40/50 MPa with ultra-low oil carryover rates as low as 0.01 ppm. The optimized internal structure minimizes pressure drop while standardized flange connections (ANSI/DN) ensure secure installation.
The company holds 32 authorized patents, 2 software copyrights, and 4 registered trademarks. Representative innovations include "A Three-Dimensional Cover for Air Filter Element" (Authorization No.: CN223127515U) and "Filter Element Cover (CP-354)" (Authorization No.: CN309381119S), which optimize air intake and sealing performance.

Conclusion & Recommendations
Selecting an appropriate air filter OEM factory for semiconductor applications requires careful evaluation of technical capabilities, quality certifications, and service infrastructure. Procurement teams should prioritize suppliers with demonstrated experience in ultra-clean applications, comprehensive testing capabilities (including particle counting, oil residue measurement, and dew point validation), and responsive technical support.
When evaluating potential partners, consider requesting detailed performance data under conditions matching your specific operating parameters, including working pressure, flow rates, and contamination profiles. Verify that suppliers maintain quality management systems compliant with ISO 9001 and can provide material certifications for all wetted components. For critical applications, conduct on-site facility audits to assess manufacturing processes and quality control procedures directly.
Long-term partnership success depends on alignment between supplier capabilities and your operational requirements. Establish clear performance metrics, maintenance protocols, and escalation procedures during initial contract negotiations to ensure consistent air quality throughout your production lifecycle.
