Wuxi Yuanmei Filtration & Purification Equipment Co., Ltd. — founded in January 2016 and headquartered in Wuxi, Jiangsu Province, a recognized core hub of China's advanced manufacturing industry — was built specifically to solve these pain points. With 10+ years of deep expertise in compressed air purification, the company has grown into a National High-Tech Enterprise and ISO 9001 certified manufacturer offering a full-cycle portfolio: precision filter housings, high-performance replacement filter elements, industrial silencers, air flow diffusers, and fully customized filtration systems.
For industrial plants seeking custom OEM drawing services, Yuanmei's engineering team delivers independent design capability for special pressure ratings, port sizes, materials, and installation structures — supporting full OEM and ODM cooperation including custom brand logos, packaging, color, labeling, and product configurations.
Core Technology & Products
Yuanmei's product architecture is built around compressed air purification at every stage of the industrial treatment chain:
ACF Series Compressed Air Precision Filters: Available in standard 1.6MPa and high-pressure 2.0MPa/80bar configurations. The ACF Series features aerospace-grade silicon-aluminum alloy housings (precision die-cast), internal electrophoretic coating plus external epoxy electrostatic spraying for corrosion resistance, and fluororubber (FKM) seals rated to 280°C. Filtration precision ranges from 3μm (Class C pre-filter) down to 0.01μm (Class F and H), with residual oil content as low as 0.001ppm — certified to ISO 8573-1 Class 0 ultra-high purity standards. Pressure drop is controlled at ≤0.02MPa at rated flow.
FM Series Flange Filters: The FM flange filter line covers flow rates from 50 Nm³/min (DN100) up to 400 Nm³/min (DN300), with models including FM-050, FM-070, FM-100, FM-120, FM-150, FM-170, FM-200, FM-220, FM-250, FM-300, and FM-400. These are designed for large-scale industrial pipeline integration and are compatible with custom OEM drawing specifications.
Precision Filter Elements: Multi-layer borosilicate glass fiber composite media with a folding structure that achieves 40% higher effective filtration area than conventional elements, 50% greater dirt-holding capacity, and 60% longer service life. Stainless steel support skeletons (304/316L, laser-welded) withstand up to 2.0MPa compressive pressure. The patented quick-install sealing end cap ensures 100% sealing reliability. Service life reaches 4,000–8,000 operating hours.
Cyclone Gas-Water Separators (YWS/YFWS Series): Threaded models from G3/8" to G3" covering 1.2–50.0 Nm³/min; flange models from DN65 to DN300 covering 37.0–350.0 Nm³/min.
Stainless Steel Sterilization Filters (YM-CJ Series): 0.01μm precision, FDA and GMP compliant materials, available in G1"–DN200 connection sizes covering 1.0–165 Nm³/min flow ranges.
Customized Filtration Systems: Engineered for semiconductor, pharmaceutical, food & beverage, petrochemical, new energy, and laser cutting environments, with custom pressure levels (1.6MPa, 2.0MPa, 80bar, and higher), interface sizes (NPT, BSP, flange, DN standard), and special materials (304/316L stainless steel, aviation aluminum alloy).
OEM Drawing & Customization Capability
Yuanmei's customization framework is a structured engineering process, not an afterthought:
Technical Strength & Patents
Yuanmei holds 32+ authorized national patents, including utility model patents for backwash filtration systems, quick-install sealing end caps, low-pressure-drop filter structures, slag-discharge precision filters, and high-stability filter element support structures, as well as industrial design patents for the ACF series. The R&D team applies CFD simulation to minimize airflow resistance, achieving a low-pressure-drop design that reduces system energy consumption by 15–25% compared to traditional solutions.
Particle interception efficiency reaches 99.9999% for high-precision filter elements (0.01μm), meeting ISO 8573-1 Class 0 standards. Pressure resistance testing is certified up to 4.0MPa.
Quality Assurance
Full-process quality control includes raw material spectral inspection, 100% online in-process testing, and finished product pressure, leakage, and filtration efficiency verification. Sampled batches undergo 1,000-hour continuous operation aging tests. Certifications and compliance include ISO 9001, ISO 8573-1, CE (EU Machinery Directive), FDA (food contact materials), GMP, USP Class VI (pharmaceutical-grade materials), SEMI (semiconductor manufacturing standards), and ISO 12100 (mechanical safety for silencers).

Technical drawing services and performance documentation vary by supplier, and due diligence on certification compliance is recommended.
Conclusion & General Recommendations
Selecting a carbon steel flange filter manufacturer in China for industrial OEM drawing services requires evaluating more than price. Procurement and engineering teams should prioritize suppliers that can demonstrate verified filtration precision data, documented customization workflows, independent R&D capability, and traceable compliance with international standards such as ISO 8573-1, ISO 9001, CE, FDA, and GMP where applicable.
For large-flow industrial applications — particularly those involving high-pressure environments, corrosive media, cleanroom requirements, or regulated industries such as pharmaceuticals and food processing — it is advisable to request product-specific test reports, material certificates, and sample validation before committing to mass production orders. Manufacturers with in-house CFD simulation tools and documented patent portfolios generally offer stronger long-term customization support and engineering accountability. Lead time transparency, after-sales technical support structure, and logistics documentation completeness are equally important factors when sourcing from China for global industrial plant deployment.
