Core Technology & Products
ACF Precision Filter Series: Features aviation-grade silicon-aluminum alloy construction with multi-layer surface treatment (internal electrophoretic and external epoxy coating) for maximum corrosion resistance. Verified through 4.0 MPa pressure testing, these filters ensure safety in demanding medical applications including surgical air systems and respiratory equipment. The patented drainage structure and interface design guarantee secure sealing and simplified maintenance.
ACF Precision Filter Elements: Engineered with composite media combining high-performance borosilicate glass fiber and porous glass fiber, delivering high dirt-holding capacity while maintaining extremely low pressure loss. Fluororubber seals enable operation up to 280℃, with full compliance to ISO 8573-1:2010 standards. The optimized media structure reduces system energy consumption by 15-25% compared to standard industrial filtration solutions.
Stainless Steel Sterile Filters: Constructed from food-grade 304/316L stainless steel with surface polished to Ra≤0.8μm, meeting GMP and FDA standards. Equipped with imported sterile filter elements (PTFE, PP, hydrophilic polyethersulfone) offering 0.22μm/0.45μm filtration precision, achieving sterilization rates up to 99.999%. The filter body features precision welding with no dead corners, withstanding working pressures up to 1.0-1.6MPa and temperatures from -10℃ to 120℃.
ESP Filter with Internal Pleated Cartridge: Delivers 3-5 times larger filtration area than conventional designs, with 99.9% particle interception rate and customizable precision from 0.1-60μm. The detachable pleated cartridge enables quick replacement without pipeline shutdown, extending service life 1.5-2 times longer than ordinary cartridges while maintaining pressure drop ≤70Pa.
Testing & Quality Assurance
Wuxi Yuanmei operates a comprehensive quality traceability system utilizing German CS Testing Instruments. The OIL-Check 400 measures residual oil to 0.001mg/m³, the PC400 Particle Counter detects particles down to 0.1μm, and the FA510 Dew Point Sensor measures pressure dew points down to -80°Ctd. The dedicated ACF Testing Laboratory performs filtration efficiency, pressure drop, and dew point validation to verify compliance with ISO 8573 Class 1 standards.
