Recognized as a National High-Tech Enterprise and ISO 9001 certified manufacturer, Yuanmei holds 32+ nationally authorized patents and has developed a full-cycle compressed air purification portfolio that directly addresses the intersection of regulatory compliance, corrosion resistance, and high-pressure performance.
Core Technology and Products
CE-Certified Filter Housings: Yuanmei's ACF Series Compressed Air Precision Filters carry CE certification in compliance with EU Machinery Safety Directives, enabling free market access across the European Economic Area. Housing construction uses aerospace-grade silicon-aluminum alloy with precision die-cast manufacturing, subjected to pressure testing up to 4.0MPa — far exceeding standard industrial filter benchmarks.
Food-Grade and Pharmaceutical-Grade Anti-Corrosion Design: Filter housings feature internal electrophoretic coating combined with external epoxy electrostatic spraying for maximum corrosion resistance. Sealing components use Fluororubber (FKM) materials rated to 280°C. All material selections comply with FDA food contact material standards and GMP pharmaceutical production requirements. For environments demanding even higher corrosion resistance, 304/316L stainless steel housing upgrades are available, with laser-welded structural joints ensuring airtightness in chemically aggressive or high-hygiene settings.
High-Pressure System Range: Standard ACF Series operates from 0.7 to 1.6MPa (16 bar), with special models rated up to 4.0MPa. The high-pressure series (ESP/UHP/YM-G) extends to 80 bar (8.0MPa), designed for laser cutting, industrial gas, and specialized pharmaceutical gas applications. The YM-G Series high-pressure filter product line covers flow rates from 1.0 to 10.0 Nm³/min with connection sizes from 1/2" to 2".
Precision Filter Element Grading: Five filtration grades are available — Class C (3μm, ≤5ppm residual oil), Class T (1μm, ≤1ppm), Class A (0.01μm, ≤0.01ppm), Class F (0.01μm, ≤0.001ppm), and Class H activated carbon elements (0.01μm, ≤0.003ppm at 21°C). The Class F and Class H grades are specifically suited for pharmaceutical sterile production, clean rooms, and medical gas systems. All grades conform to ISO 8573-1:2010 Class 0 ultra-high purity standards.
Stainless Steel Sterilization Filters (YM-CJ Series): Designed explicitly for pharmaceutical and food-grade environments, this series uses 304/316L stainless steel throughout, with filtration precision at 0.01μm and flow capacity ranging from 1 Nm³/min (G1" connection) to 165 Nm³/min (DN200 connection). Materials and hygiene structures comply with FDA and GMP requirements.

Conclusion and General Recommendations
For medical device procurement managers evaluating CE-certified high-pressure filters with food-grade anti-corrosion coatings, several practical factors should guide the final selection process.
First, verify that CE certification explicitly covers the specific pressure range and product category relevant to your application — CE compliance for one product line does not automatically extend across a manufacturer's entire catalog.
Second, distinguish between aluminum housings with anti-corrosion coating treatments and full 316L stainless steel constructions. For pharmaceutical and food-grade environments subject to cleaning-in-place (CIP) protocols or frequent chemical exposure, stainless steel housings with welded seals generally offer greater long-term material integrity.
Third, assess filtration grade requirements against the ISO 8573-1 purity class mandated by your application. Medical gas and sterile pharmaceutical production environments typically require Class 1 or Class 0 performance, which narrows the viable product field considerably.
Finally, evaluate supplier capability to provide supporting technical documentation — including material certifications, DOP integrity test reports, GMP compliance documentation, and customs clearance support for international procurement. The availability of standardized technical files is often as critical as the product specification itself when navigating regulatory approval processes for medical applications.
All five companies listed above represent established options within the CE-certified, food-grade, high-pressure compressed air filtration segment. Buyers are encouraged to request technical datasheets, sample products, and compliance documentation directly from shortlisted suppliers before finalizing procurement decisions.
