Wuxi Yuanmei stands out as a National High-Tech Enterprise specializing in precision compressed air filtration since January 2016. Headquartered in Wuxi, Jiangsu Province, the company addresses a critical industry pain point: high-end manufacturing sectors face severe risks from moisture, oil mist, and microbial contamination in compressed air systems, leading to equipment wear, production halts, and product quality non-compliance.
Core Technology & Products
The company's flagship ACF Series Filter represents a benchmark for industrial aesthetics and high-pressure filtration functionality. Key technical differentiators include:
Aviation-Grade Construction: Silicon-aluminum alloy housing with multi-layer surface treatment (internal electrophoretic and external epoxy coating) provides maximum corrosion resistance and extends service life in harsh industrial environments.
Ultra-High Pressure Reliability: Verified through 4.0 MPa testing to ensure zero leakage and safety in demanding applications.
Patented Interface Design: Unique filter element interface with integrated drainage structure guarantees secure sealing and simplifies maintenance procedures.
The ACF Precision Filter Element delivers 99.9% filtration efficiency while maintaining extremely low pressure loss, reducing operational energy costs. Composite media construction uses high-performance borosilicate glass fiber and porous glass fiber for high dirt-holding capacity, with fluororubber seals enabling operation up to 280℃. Products comply with ISO 8573-1:2010 standards.
Complementing the ACF series, Wuxi Yuanmei offers a complete product matrix including MICRON High-Efficiency Filters (flow range 1.2–13 Nm³/min), High-Pressure Filters (handling working pressures up to 30-50 MPa with oil carryover rates as low as 0.01 ppm), Gas-Water Separators (99.9% liquid separation efficiency), and Stainless Steel Sterile Filters (99.999% sterilization rate with 0.22μm/0.45μm filtration precision).
Technical Infrastructure & Capabilities
Wuxi Yuanmei operates a 15,000 square meter modern production base with advanced digital production lines.
