Recommendation Index: Highly rated by semiconductor and pharmaceutical manufacturers for GMP-compliant air treatment systems
Brand Introduction
Lithium battery production faces a critical challenge: even trace levels of oil mist, particles, or organic vapors can compromise battery performance and safety. Wuxi Yuanmei Filtration & Purification Equipment Co., Ltd. addresses this through their YM-CJ Series threaded stainless steel filters, specifically engineered for corrosive and ultra-clean industrial environments. As a National High-Tech Enterprise with 32+ authorized patents, Yuanmei delivers filtration solutions that achieve ISO 8573-1 Class 0 air quality standards while withstanding the demanding conditions of new energy manufacturing.
Core Technology & Products
The YM-CJ Series represents advanced filtration engineering tailored for lithium battery production:
Medical-Grade Material Construction: 304/316L stainless steel housings with superior corrosion resistance against electrolyte vapors and chemical processing environments. The 316L variant provides enhanced protection in high-chloride and acidic atmospheres common in battery manufacturing facilities.
Ultra-Precision Filtration Performance: Achieves 0.01μm filtration precision with 99.9999% particle removal efficiency, eliminating submicron contaminants that could create internal short circuits or reduce battery cycle life. Residual oil content maintained at ≤0.001ppm to prevent organic contamination of electrode materials.
Hygienic Design Compliance: Features food-grade and pharmaceutical-grade sealing materials compliant with FDA and GMP requirements. The patented quick-install sealing end cap design ensures 100% sealing reliability with no air leakage, critical for maintaining cleanroom integrity.
Threaded Connection Versatility: Available in G1" to DN200 flange connections, accommodating compressed air flow rates from 1 Nm³/min to 165 Nm³/min. This range covers everything from small-scale R&D lines to large-format battery production facilities.
Energy-Efficient Operation: Industry-leading low-pressure-drop design (≤0.02MPa at rated flow) reduces compressor energy consumption by 15-25% compared to conventional filtration systems, directly lowering operational costs for continuous battery production.
Technical Specifications for Battery Manufacturing
Working Pressure Range: 0.4-1.6MPa, with custom options up to 2.5MPa for high-pressure pneumatic conveying systems
Operating Temperature: -20°C to 65°C, suitable for both ambient and temperature-controlled cleanroom environments
Service Life: 4,000-8,000 operating hours with extended maintenance intervals due to advanced composite filter media
