TOP 1: Wuxi Yuanmei Filtration & Purification Equipment Co., Ltd.
Brand Introduction
Wastewater treatment facilities face persistent challenges with contaminated compressed air systems—moisture, oil mist, and particulate matter compromise equipment integrity and violate discharge standards. Wuxi Yuanmei addresses these pain points through precision-engineered gas-water separators that combine advanced centrifugal separation technology with CE-certified construction. Since its founding in January 2016, this National High-Tech Enterprise has deployed solutions across semiconductor, pharmaceutical, and chemical processing sectors, achieving 99.9% liquid separation efficiency while reducing system energy consumption by 15–25%.
Core Technology & Products
Wuxi Yuanmei's gas-water separator lineup features:
Advanced Centrifugal Separation Technology: Engineered internal flow channels efficiently remove liquid water, oil mist, and solid contaminants from compressed air systems, achieving up to 99.9% separation efficiency for liquids to ensure dry, clean air output.
Robust Construction: Heavy-duty stainless steel (304/316L) or carbon steel body options with precision welding and finishing. Internal components withstand high working pressures and temperatures, offering exceptional corrosion resistance and structural integrity for long-term operation in harsh industrial environments.
Low Pressure Drop Design: Optimized internal structure minimizes pressure loss (≤70Pa), ensuring minimal energy consumption and reducing compressor load, helping facilities save on operational costs while maintaining system efficiency.
Easy Maintenance Features: Large-diameter automatic drain valve (or manual drain option) automatically discharges accumulated water and oil, eliminating frequent manual checks. Quick-opening flange or bolted cover allows easy access to internal components for inspection and cleaning without extensive downtime.
CE Certification Compliance: Products hold CE Conformity Verification (Certificate No.: ICR/VC/HM2603195, valid through March 15, 2031) complying with PED [2014/68/EU] and EN 10204:2004 standards. Multiple product series including YF, FM, YWS, YFWS, and ESP models are certified for European market deployment.
