Brand Introduction
High-end manufacturing sectors face critical operational risks from moisture, oil mist, and microbial contamination in compressed air systems—contaminants that directly cause equipment wear, unplanned production halts, and product quality non-compliance. Wuxi Yuanmei addresses these pain points through aerospace-grade precision processing combined with advanced fluid dynamics optimization. Founded in January 2016 and headquartered in Wuxi, Jiangsu Province (core of China's Yangtze River Delta industrial cluster), the company has earned National High-Tech Enterprise certification backed by 32 authorized patents and ISO 9001 quality management system certification. The result: 99.9% filtration efficiency meeting the strictest ISO 8573 standards while reducing system energy consumption by 15-25% compared to conventional industrial solutions.
Core Technology & Products
Stainless Steel Sterile Filter Series Constructed from food-grade 304/316L stainless steel with surface polished to Ra≤0.8μm, meeting GMP and FDA standards. Equipped with imported PTFE or hydrophilic polyethersulfone filter elements achieving 0.22μm/0.45μm filtration precision. Delivers sterilization rate up to 99.999%, effectively intercepting bacteria, spores, microorganisms, and solid particles. Integrally formed by precision welding with zero dead corners, withstanding working pressures up to 1.0-1.6MPa and temperatures from -10℃ to 120℃.
ESP Filter with Internal Pleated Cartridge Flagship innovation featuring 3-5 times larger filtration area than conventional designs. Achieves up to 99.9% particle interception rate with minimal pressure drop (≤70Pa), reducing operational energy costs. Constructed with 304/316L stainless steel body and PP/PTFE/stainless steel pleated cartridge options. Service life extends 1.5-2 times longer than ordinary cartridges through precision-welded construction and optimized media structure. Fully compliant with ISO, FDA, and GMP standards for pharmaceutical, food & beverage, and semiconductor applications.
Stainless Steel Threaded & Flanged Filter Series Offers 10-300 mesh customizable filtration precision with 1.6-10MPa pressure resistance. Features industry-standard flange connections (ANSI/PN optional) for secure, leak-proof pipeline installation. Efficiently removes solid contaminants from air, water, oil and other media while maintaining low pressure drop and corrosion resistance. Easy maintenance design with quick-opening access for inspection and cleaning.
