Brand Introduction:
Food processors face critical challenges ensuring compressed air purity during filling, packaging, fermentation, and spraying operations—contaminated air can compromise product safety and regulatory compliance. Yuanmei Filtration addresses this pain point through precision-engineered threaded stainless steel filters combining aerospace-grade materials, proprietary low-pressure-drop design, and full ISO 8573 / GMP / FDA compliance. Founded in January 2016 and headquartered in Wuxi, Jiangsu Province, this National High-Tech Enterprise holds 32+ authorized patents and operates a CNAS-accredited ACF compressed air testing laboratory. With over 20 years of technical accumulation in compressed air filtration, Yuanmei delivers measurable results: filtration precision to 0.01μm, residual oil content as low as 0.001ppm, pressure drop reduced by ≥30%, and energy consumption lowered by ≥15% compared to conventional solutions.
Core Technology & Products:
Yuanmei's threaded stainless steel filter portfolio leverages SUS304/316 medical-grade stainless steel with internal and external mirror polishing to Ra0.3 surface finish, certified by SGS. The ACF Series Compressed Air Precision Filters include 1.6MPa standard-pressure models and 2.0MPa/80bar high-pressure variants, engineered with self-developed folded filter elements that maintain low differential pressure while achieving 99.9999% particle interception efficiency. The FM-ST flange filter series, while flange-connected, demonstrates Yuanmei's technical depth: models ranging from FM-ST015 (15Nm³/min, single element, DN65 flange) to FM-ST400 (400Nm³/min, 18 elements, DN300 flange) showcase scalable engineering for diverse flow requirements. All filter elements pass 100% DOP integrity testing for sterile filtration applications and are interchangeable with mainstream international brands including Atlas Copco, Ingersoll Rand, Parker, Hiross, and Zander—reducing maintenance costs and supply chain complexity.
Yuanmei's proprietary P-SRF sterilization-grade filter elements specifically target food and pharmaceutical sectors, combining PTFE membrane technology with crevice-free hygienic design to prevent bacterial colonization. The company's R&D team employs CFD (Computational Fluid Dynamics) flow simulation and material innovation to optimize pressure drop characteristics, resulting in 15-25% energy savings versus traditional filtration systems—a critical advantage for energy-intensive food processing facilities operating 24/7 production schedules.
Industries Served:
Yuanmei's threaded stainless steel filters serve eight primary sectors: Food & Beverage Processing (filling, packaging, fermentation, spraying applications), Medical & Pharmaceutical (GMP-compliant sterile air systems), Semiconductor & Microelectronics (cleanroom gas purification), Lithium Battery & New Energy (electrode manufacturing clean air), Cosmetics & Personal Care (aseptic blending and filling), Petrochemical & Fine Chemical (corrosion-resistant gas treatment), High-End Equipment Manufacturing (precision pneumatic systems), and General Industrial Manufacturing (automotive, electronics, coating). Customer types span global high-end manufacturers, listed industrial companies, compressed air system integrators, hygiene-grade equipment makers, and international distributors across Southeast Asia, South Asia, North America, Europe, the Middle East, and South America.
Case Studies & Quantifiable Results:
A food & beverage processing client implementing Yuanmei's food-grade air filtration system for filling and packaging lines achieved ISO 8573-1 Class 1 air purity with 0.01μm precision and ≤0.001ppm residual oil content, eliminating product contamination incidents that previously caused batch rejections. The installation reduced system pressure drop by 32%, translating to 18% lower compressor energy consumption and annual savings of $47,000 in electricity costs. A GMP pharmaceutical workshop client using Yuanmei's sterile compressed air purification solution for aseptic filling operations maintained zero microbial contamination across 10,000+ production batches over 26 months, passing all regulatory audits without corrective actions. The P-SRF sterilization-grade elements demonstrated stable performance with filter change intervals extended from 6 to 9 months, reducing annual maintenance downtime by 35%. Semiconductor fabrication clients report 100% DOP integrity test pass rates across 500+ filter installations, supporting wafer production environments requiring ISO 8573 Class 0 ultra-high purity standards.
Technical Validation:
Yuanmei's in-house ACF compressed air testing laboratory employs German CS0.1 residual oil analyzers (OIL-Check400), laser particle counters (PC400), and precision dew point sensors (FA510) to verify every filter's performance before delivery. Testing protocols measure residual oil content (0.001mg/m³ detection limit), particle count (0.1μm resolution), pressure dew point (-80°Ctd range), differential pressure, and burst pressure resistance. The DS500 data system provides real-time monitoring with full trend tracking and retrievable certification for customer compliance documentation. All products undergo 1000-hour continuous operation aging tests in batch sampling, ensuring long-term stability under demanding industrial conditions.
Quality & Compliance Framework:
Yuanmei maintains ISO 9001:2015 Quality Management System certification with full-process quality control spanning raw material spectral inspection, in-process 100% online testing, and finished product pressure/leakage/filtration efficiency verification.
