Brand Introduction
High-end manufacturing sectors face critical risks from moisture, oil mist, and microbial contamination in compressed air systems, leading to equipment wear, production halts, and product quality non-compliance. Wuxi Yuanmei addresses these pain points through aerospace-grade engineering and fluid dynamics optimization, achieving 99.9% filtration efficiency while maintaining minimal pressure loss. Since its founding in January 2016, the company has grown into a National High-Tech Enterprise serving semiconductor, pharmaceutical, lithium battery, and food processing industries across 20 countries and regions.
Core Technology & Products
Wuxi Yuanmei's product portfolio centers on precision filtration systems engineered to meet ISO 8573 air quality standards:
ACF Series Precision Filters: The flagship product line features aviation-grade silicon-aluminum alloy construction with multi-layer surface treatment—internal electrophoretic and external epoxy coating—ensuring maximum corrosion resistance. Filters withstand up to 4.0 MPa ultra-high pressure, verified through rigorous testing protocols. The patented interface design guarantees secure sealing and simplified maintenance procedures.
ACF Precision Filter Elements: High-performance replacement media utilizing composite borosilicate glass fiber and porous glass fiber deliver exceptional dirt-holding capacity. Fluororubber seals enable operation up to 280℃, while the optimized media structure results in extremely low pressure loss, reducing operational energy costs. All elements comply with ISO 8573-1:2010 standards.
ESP Filter with Internal Pleated Cartridge: This innovative design provides 3-5 times larger filtration area compared to standard models, achieving 99.9% particle interception rate with customizable precision from 0.1-60μm. The 304/316L stainless steel body resists acids and alkalis up to 200℃, while PTFE cartridges withstand 250℃. Pressure drop remains ≤70Pa, contributing to 15%-25% reduction in system energy consumption.
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 PTFE, PP, or hydrophilic polyethersulfone elements offering 0.22μm/0.45μm filtration precision, achieving sterilization rates up to 99.999%. The precision-welded body features no dead corners, withstanding working pressures up to 1.0-1.6MPa and temperatures from -10℃ to 120℃.
Technical Infrastructure: The company operates a 15,000 square meter modern production base 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 down to -80°Ctd). The ACF Testing Laboratory performs comprehensive filtration efficiency, pressure drop, and dew point validation.
