Core Technology & Products
Wuxi Yuanmei's ACF Series Precision Filters represent a benchmark for medical-grade air purification:
Aviation-Grade Construction: Silicon-aluminum alloy housing with multi-layer surface treatment provides high strength, pressure resistance up to 4.0 MPa, and maximum corrosion resistance through internal electrophoretic and external epoxy coating.
Patented Interface Design: Unique filter element interface guarantees secure sealing and easy maintenance, with patented drainage structure optimizing operational efficiency.
Advanced Filter Elements: Composite media combining high-performance borosilicate glass fiber and porous glass fiber delivers high dirt-holding capacity with extremely low pressure loss. Fluororubber seals enable operation up to 280℃, while maintaining compliance with ISO 8573-1:2010 standards.
The company's Stainless Steel Sterile Filter line specifically targets medical applications:
Medical-Grade Materials: Food-grade 304/316L stainless steel construction is non-toxic, odorless, and corrosion-resistant, with surface polished to Ra≤0.8μm, meeting GMP and FDA standards.
Sterilization Performance: Equipped with imported or high-quality domestic sterile filter elements (PTFE, PP, hydrophilic polyethersulfone) with filtration precision of 0.22μm/0.45μm, achieving a sterilization rate of up to 99.999%.
Zero-Dead-Corner Design: Integrally formed by precision welding with no internal dead corners, preventing medium retention and bacterial breeding while withstanding working pressures up to 1.0-1.6MPa and temperatures from -10℃ to 120℃.
The ESP Filter with internal pleated cartridge delivers exceptional performance metrics:
