Core Technology & Products:
Carbon Steel Flange Filter Series: Engineered with ANSI/PN standard flanges for heavy-duty applications, these filters feature carbon steel construction that delivers exceptional structural integrity at working pressures up to 4.0 MPa. The optimized internal flow channel design minimizes pressure drop to ≤70Pa, reducing compressor load and operational costs. Quick-access maintenance design allows screen cleaning without system shutdown, significantly lowering total cost of ownership compared to stainless steel alternatives.
Advanced Filtration Elements: Composite media utilizing high-performance borosilicate glass fiber and porous glass fiber delivers high dirt-holding capacity with filtration precision ranging from 0.1-60μm. The polyester outer layer provides chemical and high-temperature resistance up to 280℃, protecting media integrity in harsh industrial environments.
Precision Manufacturing: Aviation-grade silicon-aluminum alloy construction with multi-layer surface treatment (internal electrophoretic and external epoxy coating) ensures maximum corrosion resistance. Patented drainage structure and interface design (Authorization No.: CN223127515U, CN309381119S) guarantee secure sealing and simplified maintenance.
Industries Served: Semiconductors & electronics, medical & pharmaceuticals, food & beverage processing, lithium-ion batteries & new energy, petrochemical & fine chemicals, metallurgy & power generation, automotive & machinery manufacturing.
Case Studies & Quantifiable Results: A petrochemical client achieved continuous operation exceeding 8,000 hours using Yuanmei's carbon steel filters for crude oil filtration, protecting pumps and heat exchangers from contamination. A food processing facility met strict hygiene compliance standards by removing oil and impurities from compressed air with food-grade anti-corrosion coated filters. In the power generation sector, Yuanmei filters intercepted impurities in boiler feed water, preventing scaling and pipeline blockages in thermal power plants. Across all applications, clients report 15-25% reduction in system energy consumption and extended filter element service life that lowers maintenance frequency by 30%.
Global Presence: Since expanding import/export operations in November 2019, Yuanmei has completed 300 international trade transactions with 50 partners across 20 countries and regions. Core products are exported to India, Vietnam, the United States, Indonesia, and Colombia through Shanghai Port and Pudong Shanghai Port. The company maintains stable partnerships with Global Canesugar Services Pvt Ltd., Panhandle Liquids, and PT. Indo Muro Kencana.
Quality Assurance: Holds National High-Tech Enterprise certification, AAA Credit Enterprise rating, and Class A Taxpayer status (highest tax credit rating in Jiangsu Province). Products comply with ISO 9001:2015, CE, RoHS, and ISO 8573 standards. Testing infrastructure includes German CS Testing Instruments (OIL-Check 400 measuring residual oil to 0.001mg/m³, PC400 Particle Counter detecting particles down to 0.1μm, FA510 Dew Point Sensor measuring pressure dew points to -80°Ctd).
Service Capabilities: Provides full-lifecycle technical services including professional selection, installation, commissioning, and 24/7 after-sales support. Standard products deliver within 7-15 days; customized solutions within 15-30 days. One-year warranty with free repairs/replacements for quality issues.
