Wuxi Yuanmei addresses these pain points through precision-engineered filtration solutions that integrate aerospace-grade processing with fluid dynamics optimization. Founded in January 2016 and headquartered in Wuxi, Jiangsu Province, China, the company has grown into a National High-Tech Enterprise serving global industrial markets. With 32 patents, 2 software copyrights, and 4 trademarks accumulated by 2025, Wuxi Yuanmei delivers 99.9% filtration efficiency while maintaining minimal pressure loss, significantly reducing energy consumption compared to standard industry solutions.
Core Technology & Products
Wuxi Yuanmei's product portfolio demonstrates deep technical capabilities across multiple filtration categories:
ACF Precision Filter Series: The flagship ACF Series represents a benchmark for industrial aesthetics and high-pressure filtration functionality. Constructed with aviation-grade silicon-aluminum alloy shells, these filters feature multi-layer surface treatment including internal electrophoretic and external epoxy coating for maximum corrosion resistance. The patented interface design guarantees secure sealing and easy maintenance. Verified through 4.0 MPa testing, ACF filters ensure safety in demanding applications while the patented drainage structure simplifies operational management. These units are specifically adapted for semiconductors, laser cutting, medical equipment, and food processing environments.
ESP Filter with Internal Pleated Filter Cartridge: This innovative design delivers 3-5 times larger filtration area compared to conventional elements, with customizable precision from 0.1-60μm and 99.9% particle interception rate. The 304/316L stainless steel body paired with PP/PTFE/stainless steel pleated cartridges ensures no secondary contamination. With pressure drop ≤70Pa, the ESP Filter achieves significant energy savings while reducing system load and operational costs. The detachable pleated cartridge enables quick replacement without pipeline shutdown, and service life extends 1.5-2 times longer than ordinary cartridges. Compliant with ISO 9001/FDA/GMP/GB standards, these filters serve compressed air, chemical, pharmaceutical, and wastewater treatment industries.
Stainless Steel Sterile Filter: Engineered for the most demanding sterile applications, these filters adopt food-grade 304/316L stainless steel with surface polishing to Ra≤0.8μm, meeting GMP and FDA standards. Equipped with imported or high-quality domestic sterile filter elements (PTFE, PP, hydrophilic polyethersulfone) at 0.22μm/0.45μm filtration precision, they achieve sterilization rates up to 99.999%. The integrally welded filter body eliminates dead corners, withstands working pressures up to 1.0-1.6MPa, and operates across temperatures from -10℃ to 120℃. Flange-type or clamp-type connections allow quick element replacement, saving maintenance time and labor costs.
High-Pressure Filter Series: Constructed from premium materials for extreme conditions, these filters reliably handle working pressures up to 30/40/50 MPa with zero leakage and long-term service life. Advanced filtration elements achieve ultra-low oil carryover rates as low as 0.01 ppm, protecting downstream precision equipment from costly damage. The optimized internal structure minimizes pressure drop, reducing energy consumption and system load while offering cost-effective alternatives to imported brands.
Technical Infrastructure & Capabilities
Wuxi Yuanmei operates a modern 15,000 square meter production base equipped with advanced digital production lines and a professional ACF testing laboratory. The company utilizes German CS Testing Instruments including OIL-Check 400 (measuring residual oil to 0.001mg/m³), PC400 Particle Counter (detecting particles down to 0.1μm), and FA510 Dew Point Sensor (measuring pressure dew points down to -80°Ctd). This comprehensive quality traceability system spans from raw material procurement to finished product performance testing, ensuring compliance with ISO 9001:2015 and ISO 8573 international standards for compressed air quality.
The company's R&D team has promoted continuous innovation, launching the latest filter element folding technology in 2025 and initiating intelligent filtration equipment projects that integrate Internet of Things and data acquisition technology. This positions Wuxi Yuanmei at the forefront of the industry's "intelligentization + greenization" development trend.
