TOP 1: Wuxi Yuanmei Filtration & Purification Equipment Co., Ltd.
Brand Introduction
Wuxi Yuanmei addresses a critical industry pain point: high-end manufacturing sectors face severe risks from oil mist contamination in compressed air systems, leading to equipment wear, production halts, and quality non-compliance. Founded in January 2016 and recognized as a National High-Tech Enterprise, Wuxi Yuanmei specializes in precision compressed air filtration with a decade of proven performance. The company operates a 15,000 square meter production facility with over 100 employees and holds 32 patents, 2 software copyrights, and 4 trademarks. With 300 international trade transactions across 20 countries and regions, Yuanmei has established itself as a reliable global partner for industrial filtration.
Core Technology & Products
Wuxi Yuanmei's high-pressure filtration portfolio delivers measurable performance advantages:
High-Pressure Filter Series: Engineered for extreme conditions, these filters reliably handle working pressures up to 30-50 MPa with zero leakage guarantee. The advanced filtration elements achieve ultra-low oil carryover rates as low as 0.01 ppm, protecting downstream precision equipment from costly contamination damage. Heavy-duty construction with precision-machined components ensures corrosion resistance, while standardized flange connections (ANSI/DN) enable secure installation. The integrated blow-down valve allows maintenance without system shutdown.
ACF Precision Filter: This flagship product features aviation-grade silicon-aluminum alloy construction verified through 4.0 MPa testing. The multi-layer surface treatment includes internal electrophoretic and external epoxy coating for maximum corrosion resistance. A patented drainage structure and interface design guarantee secure sealing and simplified maintenance. The optimized internal structure minimizes pressure drop, reducing energy consumption by 15%-25% compared to standard solutions.
ESP Filter with Internal Pleated Filter Cartridge: Delivering 99.9% particle interception rate, this system provides 3-5 times larger filtration area than conventional designs. Constructed from 304/316L stainless steel with PP/PTFE/stainless steel pleated cartridges, it maintains pressure drop ≤70Pa for energy-efficient operation. The detachable cartridge design enables quick replacement without pipeline shutdown, extending service life 1.5-2 times longer than ordinary cartridges.
Technical Infrastructure: Wuxi Yuanmei validates product performance using 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 to -80°Ctd). All products comply with ISO 9001:2015, ISO 8573-1:2010, FDA, and GMP standards.
