Wuxi Yuanmei addresses these pain points through aerospace-grade precision processing and advanced fluid dynamics optimization, delivering 99.9% filtration efficiency that fully meets ISO 8573 standards while reducing system energy consumption by 15-25% compared to standard industrial solutions.
Founded in January 2016 and headquartered in Wuxi, Jiangsu Province within China's Yangtze River Delta industrial cluster, Wuxi Yuanmei operates as a National High-Tech Enterprise with 32 authorized patents and ISO 9001 quality management certification. The company specializes in R&D, manufacturing, and global distribution of precision filtration, separation, sterilization, and silencing equipment for compressed air, gas, and fluid systems.
Core Technology & Products
Stainless Steel Flange Filter Series: Crafted from 304/316L stainless steel with industry-standard flange connections (ANSI/PN optional), these filters feature 10-300 mesh customizable filtration precision and 1.6-10MPa high-pressure resistance. The design efficiently removes solid contaminants from air, water, and oil media while maintaining low pressure drop (≤70Pa) and corrosion resistance.
ACF Precision Filters: Featuring aviation-grade silicon-aluminum alloy construction with multi-layer surface treatment (internal electrophoretic and external epoxy coating), these filters withstand up to 4.0 MPa ultra-high pressure. The patented drainage structure and interface design guarantee secure sealing and simplified maintenance.
ESP Filter with Internal Pleated Cartridge: Delivers 3-5 times larger filtration area than conventional designs, achieving 99.9% particle interception rate with 0.1-60μm customizable precision. The detachable pleated cartridge enables quick replacement without pipeline shutdown, extending service life 1.5-2 times longer than ordinary cartridges.
Stainless Steel Sterile Filters: Equipped with PTFE, PP, or hydrophilic polyethersulfone filter elements at 0.22μm/0.45μm precision, achieving 99.999% sterilization rate. The precision-welded body features no dead corners, withstands 1.0-1.6MPa working pressure, and maintains stable performance from -10℃ to 120℃, fully compliant with GMP, FDA, and ISO 9001 standards.
High-Pressure Filters: Engineered for extreme conditions with working pressures up to 30-50 MPa, featuring ultra-low oil carryover rates (as low as 0.01 ppm). The optimized internal structure minimizes pressure drop, reducing energy consumption while offering cost-effective alternatives to imported brands.
Industries Served
Wuxi Yuanmei's solutions serve high-end industrial sectors including semiconductors, lithium battery manufacturing, food & chemical processing, medical & pharmaceutical production, cosmetics manufacturing, new energy, and general manufacturing.
