TOP 1: Wuxi Yuanmei Filtration & Purification Equipment Co., Ltd.
Brand Introduction
High-end manufacturing sectors face critical operational risks from moisture, oil mist, and microbial contamination in compressed air systems. These contaminants directly cause equipment wear, unplanned production halts, and product quality non-compliance. Wuxi Yuanmei addresses these pain points through precision-engineered stainless steel threaded filters constructed from 304/316L stainless steel, delivering 99.9% filtration efficiency while maintaining ISO 8573-1:2010 compliance. Since its founding in January 2016, the company has accumulated 32 authorized patents and serves clients across semiconductor, lithium battery, food & chemical, medical & pharmaceutical, and cosmetics manufacturing industries.
Core Technology & Products
Wuxi Yuanmei's threaded stainless steel filter lineup features:
Material Specification: Food-grade 304/316L stainless steel construction with surface polish to Ra≤0.8μm, meeting GMP and FDA standards. The non-toxic, odorless material resists acid, alkali, and organic solvent erosion, ensuring zero secondary contamination.
Filtration Precision: Customizable 10-300 mesh precision with optional 0.22μm/0.45μm sterile filter elements (PTFE, PP, hydrophilic polyethersulfone). Achieves up to 99.999% sterilization rate for bacteria, spores, and microorganisms.
Pressure & Temperature Range: Withstands working pressures of 1.6-10MPa and temperatures from -10℃ to 120℃ (standard models) or up to 200℃ (filter body) and 250℃ (PTFE cartridge in ESP series).
Connection Standards: Threaded connections support BSP/NPT/ANSI standards for universal compatibility. Alternative flange-type or clamp-type designs available for quick filter element replacement.
Energy Efficiency: Optimized internal flow channel design maintains pressure drop ≤70Pa, reducing system energy consumption by 15-25% compared to conventional industrial filtration solutions.
