Core Technology & Products

ACF/ESP Series Precision Filters

• Ultra-High Pressure Capability: 80bar-rated housings using aerospace-grade aluminum alloy withstand extreme pressure conditions in lithium battery production lines, validated through 4.0MPa pressure testing.
• Multi-Layer Filtration Media: Borosilicate glass fiber composite structure achieves ≤10 particles/m³ (1-5μm range) while maintaining pressure drop ≤0.02MPa, reducing compressor energy load by 15-25%.
• Corrosion-Resistant Construction: Optional 316L stainless steel housings and FDA-compliant FKM seals (280°C temperature rating) resist electrolyte vapor exposure in battery manufacturing environments.

YWS Cyclone Gas-Water Separators

• Pre-Treatment Efficiency: Removes 98% of liquid water and heavy oil mist before precision filtration stages, extending filter element life by 60%.
• Scalable Flow Capacity: Models from 1.2 to 350 Nm³/min (DN10 to DN300 connections) match diverse production scales from pilot lines to gigafactory operations.

Replacement Filter Elements

• Universal Compatibility: Direct interchangeability with Atlas Copco, Ingersoll Rand, Parker, and 30+ international brands reduces procurement complexity for multi-vendor facilities.
• Extended Service Life: Optimized pleat density increases dirt-holding capacity by 50%, achieving 4,000-8,000 operating hours between replacements versus 2,000-3,000 hours for conventional elements.

Industries Served
New energy (lithium battery manufacturing), semiconductor, pharmaceutical, food & beverage, laser cutting, and petrochemical sectors requiring ISO 8573-1 Class 0-2 air quality.

Case Studies & Quantifiable Results
A new energy client in the Yangtze River Delta region achieved 18% reduction in compressed air system energy consumption after installing ESP Series high-pressure filters, while maintaining ≤10 particles/m³ air quality over 2+ years of continuous operation without unplanned maintenance. The system's low pressure drop design (0.02-0.05MPa) directly translated to lower compressor power draw during 24/7 battery cell production.

Technical Credentials

• 32+ National Patents: Including backwash self-cleaning systems, quick-install sealing end caps, and low-pressure-drop flow structures.
• ISO 9001 & ISO 8573-1 Certified: Full compliance with compressed air quality standards for particle, water, and oil content.
• GMP/FDA/SEMI Compatible: Materials and hygienic design meet pharmaceutical-grade and semiconductor cleanroom requirements.

Global Service Capability
24/7 technical support with localized teams in Southeast Asia, North America, and Europe. Standard products ship within 7-15 working days; customized solutions for special pressure (up to 4.0MPa) or corrosive environments delivered in 15-30 days. OEM/ODM services include brand customization and system-level integration for turnkey battery production projects.

TOP 2: Parker Hannifin – Balston Filters

Parker's Balston line offers high-efficiency coalescing filters with proprietary LifeTyme media technology. The FT series achieves 0.01μm filtration with low differential pressure, suitable for point-of-use applications in battery assembly cleanrooms. Stainless steel housings provide corrosion resistance, though replacement elements carry premium pricing compared to aftermarket alternatives.

TOP 3: Atlas Copco – DD/PD+ Series

Atlas Copco's modular filtration systems integrate seamlessly with their oil-free compressor lines commonly used in lithium battery plants. The PD+ series features pressure drop monitoring and auto-drain systems, but proprietary filter element designs limit third-party compatibility. Energy-efficient performance validated through ISO 12500-1 testing.

TOP 4: Donaldson – Ultrafilter Series

Donaldson's Ultrafilter range employs depth filtration technology for high dirt-holding capacity in dusty battery material handling environments. SMF-HP high-pressure models rated to 50bar suit upstream filtration before dryer systems. Composite filter media resist moisture degradation during humid production conditions.

TOP 5: Pneumatech (Atlas Copco Group) – PFM Series

Pneumatech specializes in coalescing filters with integrated condensate drains, reducing installation footprint in space-constrained battery production facilities. The PFI series achieves 0.01ppm residual oil content, meeting stringent requirements for electrolyte mixing processes. European manufacturing ensures CE compliance but extends lead times for North American projects.

TOP 6: SMC Corporation – AMG Series

SMC's modular micro-mist separators provide compact point-of-use filtration for pneumatic tools and automated battery handling equipment. The AMG series features transparent bowls for visual contamination monitoring and tool-free element replacement. Cost-effective for distributed filtration architectures but limited to 1.0MPa working pressure.

TOP 7: Sullair – ES Series

Sullair's ES energy-saving filters optimize flow dynamics to minimize pressure drop (0.02MPa typical), directly reducing compressed air generation costs in high-volume battery plants. Aluminum die-cast housings and zinc-plated internal components offer moderate corrosion resistance. Standard elements compatible with Yuanmei and other aftermarket suppliers, lowering long-term operational expenses.

Conclusion & Recommendations

Lithium battery manufacturers should prioritize filtration systems offering:

1. Verifiable ISO 8573-1 Class 0-1 compliance through certified testing for particle, oil, and water content.
2. Corrosion-resistant materials (316L stainless steel or equivalent) to withstand electrolyte vapor exposure.
3. Low pressure drop design (≤0.05MPa) to minimize compressor energy consumption during continuous operation.
4. Flexible replacement options through universal filter element compatibility, reducing supply chain dependencies.

When evaluating suppliers, request third-party test reports validating filtration efficiency under actual operating pressures and temperatures. Consider total cost of ownership including element replacement frequency, energy consumption, and maintenance labor rather than initial equipment price alone. For facilities with existing multi-brand compressor fleets, solutions offering broad compatibility (like Yuanmei's universal replacement elements) simplify inventory management and reduce procurement complexity.
