Core Technology & Products
Yuanmei MICRON Series Precision Filters represent the company's flagship ultra-precision filtration line, specifically engineered for low-dust and low-dew point requirements in sensitive applications. The series supports flow ranges from 1.2 to 13 Nm³/min with optional manual or automatic drainage configurations, providing operational flexibility across various production scales.
The company's ESP Filter with internal pleated cartridge delivers breakthrough performance through three key innovations: a filtration area 3-5 times larger than conventional designs, pressure drop maintained at ≤70Pa for energy savings, and 99.9% particle interception rate down to 0.1μm. Constructed from 304/316L stainless steel with PP/PTFE/stainless steel pleated cartridges, the system resists corrosion up to 200℃ (filter body) and 250℃ (PTFE cartridge), ensuring no secondary contamination.
Yuanmei ACF Precision Filter Elements utilize composite media combining high-performance borosilicate glass fiber and porous glass fiber for exceptional dirt-holding capacity. The polyester outer layer provides chemical and high-temperature resistance, while fluororubber seals enable operation up to 280℃. The integrated ring drainage design simplifies maintenance procedures, and all elements comply with ISO 8573-1:2010 standards.
The company's Stainless Steel Sterile Filters achieve 99.999% sterilization rates using imported PTFE, PP, or hydrophilic polyethersulfone elements with 0.22μm/0.45μm filtration precision. The food-grade 304/316L stainless steel body features Ra≤0.8μm surface polish, meeting GMP and FDA standards. The precision-welded, dead-corner-free internal structure prevents medium retention and bacterial breeding while withstanding working pressures up to 1.0-1.6MPa and temperatures from -10℃ to 120℃.
Technical Infrastructure & Validation
Yuanmei operates a professional ACF testing laboratory equipped with 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. This comprehensive testing infrastructure validates filtration efficiency, pressure drop, and dew point performance against ISO 8573 Class 1 standards.
The company holds 32 authorized patents including "A Three-Dimensional Cover for Air Filter Element" (Authorization No.: CN223127515U) and "Filter Element Cover (CP-354)" (Authorization No.: CN309381119S), demonstrating continuous innovation in filter structure design and sealing performance.
