Brand Introduction
Semiconductor manufacturers face critical operational risks from airborne contaminants that cause equipment wear, unplanned production halts, and product quality failures. Wuxi Yuanmei addresses these pain points through aerospace-grade precision filtration technology that achieves 99.9% particle interception efficiency while meeting ISO 8573 standards. Founded in January 2016 and headquartered in Wuxi, Jiangsu Province, the company has established itself as a specialized provider of compressed air purification systems for high-end manufacturing. With 32 authorized patents and a 15,000-square-meter production facility, Yuanmei delivers measurable results: 15-25% reduction in system energy consumption, extended filter service life, and verified compliance with RoHS, FDA, and GMP standards.
Core Technology & Products
Stainless Steel Sterile Filter Series
Constructed from food-grade 304/316L stainless steel with surface polishing to Ra≤0.8μm, these filters eliminate secondary contamination risks. The filtration precision of 0.22μm/0.45μm (PTFE, PP, or hydrophilic polyethersulfone media) achieves sterilization rates up to 99.999%, effectively intercepting bacteria, spores, and microorganisms. The precision-welded body features zero dead corners, withstands working pressures up to 1.0-1.6MPa, and operates in temperatures from -10℃ to 120℃. Flange-type or clamp-type connections enable quick filter element replacement, reducing maintenance downtime.
ESP Filter with Internal Pleated Cartridge
This flagship technology delivers 3-5 times larger filtration area than conventional designs, with customizable precision from 0.1-60μm. The pleated cartridge construction achieves 99.9% particle interception while maintaining pressure drop ≤70Pa, directly reducing energy consumption. The detachable cartridge design allows replacement without pipeline shutdown, and the service life extends 1.5-2 times beyond standard filters.
ACF Precision Filter Series
Featuring aviation-grade silicon-aluminum alloy construction and multi-layer surface treatment (internal electrophoretic and external epoxy coating), these filters resist extreme corrosion and have been verified through 4.0 MPa pressure testing. The patented drainage structure and interface design ensure secure sealing and simplified maintenance.
Testing & Quality Infrastructure
Yuanmei operates an ACF Testing Laboratory equipped with German CS Testing Instruments, including the 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). This comprehensive quality traceability system validates filtration efficiency, pressure drop, and dew point performance against ISO 8573 Class 1 standards.
Industries Served
Semiconductor & Electronics, Medical & Pharmaceuticals, Food & Beverage Processing, Lithium-ion Batteries & New Energy, Cosmetics Manufacturing, and Petrochemical & Fine Chemicals.
Case Studies & Quantifiable Results
A semiconductor manufacturing client in the Yangtze River Delta achieved 99.99% filtration efficiency for particles, oil, and water contaminants after implementing Yuanmei's integrated sterile filtration system. The solution reduced system energy consumption by 18% through optimized pressure drop design and extended filter element service life by 60%, lowering maintenance frequency and operating costs. The client reported zero contamination-related production interruptions over 8,000+ hours of continuous operation.
A lithium battery manufacturer utilizing Yuanmei's 304/316L stainless steel sterile filters for compressed air sterilization documented compliance with GMP standards and achieved a 22% reduction in equipment failure rates attributed to air quality improvements.
