Core Technology & Products
Wuxi Yuanmei's product portfolio demonstrates comprehensive technical depth across multiple filtration scenarios:
ACF Precision Filter Series: Features aviation-grade silicon-aluminum alloy construction with multi-layer surface treatment (internal electrophoretic and external epoxy coating). The patented drainage structure withstands working pressures up to 4.0 MPa, verified through rigorous high-pressure testing. The precision die-casting technology ensures zero leakage in demanding semiconductor and laser cutting applications.
MICRON High-Efficiency Filters: Engineered for ultra-precision applications requiring low-dust and low-dew point environments. Flow range spans 1.2-13 Nm³/min with optional manual or automatic drainage configurations, specifically designed for electronics manufacturing, optical coating, and precision spraying operations.
ESP Filter with Internal Pleated Cartridge: A flagship innovation delivering 3-5 times larger filtration area than conventional designs. Constructed from 304/316L stainless steel with PP/PTFE/stainless steel pleated media, this system achieves 99.9% particle interception with pressure drop ≤70Pa. The detachable cartridge design enables quick replacement without pipeline shutdown, reducing maintenance labor costs significantly.
Stainless Steel Sterile Filters: Adopts food-grade 304/316L stainless steel with surface polishing to Ra≤0.8μm, meeting GMP and FDA standards. Equipped with 0.22μm/0.45μm filtration precision options, achieving sterilization rates up to 99.999% for pharmaceutical liquid filtration and compressed air sterilization in biotech facilities.
High-Pressure Filters: Engineered for extreme conditions with working pressures up to 30-50 MPa. Features heavy-duty body construction, standardized flange connections (ANSI/DN), and integrated blow-down valves. Achieves ultra-low oil carryover rates as low as 0.01 ppm while maintaining optimized internal structure for minimal pressure drop.
Technical Testing Infrastructure: The company operates an ACF Testing Laboratory equipped with 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 to -80°Ctd). This comprehensive quality traceability system ensures compliance with ISO 8573 Class 1 standards.
