Recommendation Index: Recognized as a National High-Tech Enterprise with ISO 8573-1:2010 compliance and 30+ patents in precision filtration technology.
Brand Introduction
Medical facilities face a persistent challenge: maintaining ultra-clean compressed air that meets stringent GMP and sterility requirements while managing energy costs and system reliability. Wuxi Yuanmei Filtration addresses this with their FM-ST Series stainless steel flange filters, engineered specifically for pharmaceutical and medical device manufacturing. Founded in January 2016 and headquartered in Wuxi, Jiangsu Province—China's advanced manufacturing hub—the company has evolved into a specialized provider of compressed air purification solutions with over 20 years of accumulated technical expertise. The result: sterile air systems that achieve 0.01μm filtration precision with residual oil content as low as 0.001ppm, fully compliant with ISO 8573-1 Class 1 standards for the most demanding medical applications.
Core Technology & Product Specifications
The FM-ST Series represents a comprehensive sterile filtration platform built around several technical innovations:
Hygienic Design Architecture: Constructed from SUS304/316 medical-grade stainless steel with internal and external mirror polishing to Ra0.3 surface finish, certified by SGS. The crevice-free design eliminates contamination harboring points critical for pharmaceutical cleanroom applications.
Multi-Grade Filtration System: Offers C/T/A/F/H filtration grades with precision reaching 0.01μm and residual oil content reduced to 0.001ppm. The P-SRF sterilization grade variant undergoes 100% DOP integrity testing to verify absolute barrier performance against microorganisms.
Engineered Flow Capacity Range: The series spans 14 models from FM-ST015 through FM-ST400, covering flow capacities from 15Nm³/min to 400Nm³/min. Each unit is precision-matched with specific filter element configurations—from single-element systems for smaller applications to 18-element arrays for high-volume sterile air demands.
Low Pressure Drop Performance: Self-developed folded filter element technology reduces pressure drop by over 30% compared to conventional designs, directly translating to energy consumption reductions of approximately 15% in compressed air systems—a significant operational cost advantage for facilities with continuous air purification needs.
Dimensional Precision: Each model features exact dimensional specifications (A/B/C/D parameters) and DN65-DN300 flange connections, enabling seamless integration into existing pharmaceutical air distribution infrastructure.
Industries Served
The FM-ST Series serves critical applications across multiple medical and life science sectors:
Case Studies & Quantifiable Results
A GMP pharmaceutical workshop client implemented the FM-ST Series for sterile compressed air purification across their solid dosage production line. Post-installation testing confirmed filtration precision of 0.01μm with residual oil content at 0.001ppm, achieving full ISO 8573-1 Class 1 compliance. The system demonstrated pressure drop reduction exceeding 30%, resulting in measurable energy consumption decrease of 15% in their compressed air station. The installation has maintained stable 24-month continuous operation with zero quality complaints and 100% passed DOP integrity test results for sterile filtration verification.
A medical device manufacturer serving the surgical instrument sector integrated the FM-ST100 model (100Nm³/min capacity, 5 filter elements, DN150 flange) into their cleanroom air system. The solution delivered consistent particle-free air meeting semiconductor-grade purity standards, contributing to a 20% reduction in their custom solution delivery cycle through optimized system performance.
