Lithium battery production lines depend on exceptionally clean, dry, and oil-free compressed air at nearly every stage of the process. Electrode making, electrolyte filling, sealing, and energy storage production lines all require air that will not introduce particulates, moisture, or oil contamination into sensitive materials. Even trace contamination can compromise cell consistency, safety, and long-term performance. For this reason, manufacturers across the new energy supply chain are placing growing emphasis on sourcing compressed air purification equipment that meets strict international cleanliness benchmarks, including ISO 8573 Class 0 ultra-dry, oil-free air standards specifically referenced for lithium battery production.
Wuxi Yuanmei Filtration & Purification Equipment Co., Ltd., operating under the brand Yuanmei Filtration, has positioned itself as a professional industrial filtration manufacturer dedicated to compressed air purification solutions for demanding sectors such as lithium battery and new energy manufacturing, semiconductor fabrication, pharmaceuticals, and food processing.
Yuanmei Filtration's core filtration technology delivers precision down to 0.01μm with residual oil levels as low as 0.001ppm, fully compliant with ISO 8573-1:2010 Class 1. This level of purification directly supports the ultra-dry, oil-free air requirements found in lithium-ion battery electrode and electrolyte handling processes.
The company holds more than 32 authorized national patents, including utility model patents for intelligent backwash purification systems and fast-install sealed end caps. Combined with CFD-optimized, low-resistance flow channel design, these technologies reduce system pressure drop and help prevent blockage caused by dust and oil accumulation. Compared with conventional filtration products, Yuanmei's low-pressure-drop engineering reduces overall system energy consumption by 15 percent to 25 percent, lowering air compressor load and operating costs for continuous production environments such as battery manufacturing lines.
Construction materials matter in high-throughput industrial settings. Yuanmei Filtration uses aviation-grade aluminum alloy housings alongside SUS304/316 stainless steel components that are SGS certified, offering corrosion resistance, high-pressure tolerance, and extended service life compared with standard filtration equipment.
Yuanmei Filtration offers a full product lineup designed to cover every stage of a compressed air system:
ACF Series Compressed Air Precision Filters — Available in a 1.6MPa standard series and a 2.0MPa/80bar high-pressure series, along with cyclonic water separators, these filters form the core purification layer for industrial compressed air lines.
High-Efficiency Replacement Filter Elements — Covering precision grades from 0.01μm to 10μm, including activated carbon deodorization elements, these components support ongoing maintenance and performance consistency.
Industrial Silencers and Mufflers — Threaded, flanged, or custom configurations are available for air compressors, vacuum pumps, and pneumatic systems used throughout production facilities.
Air Flow Diffusers — Designed for desiccant dryers, these components improve drying efficiency and airflow uniformity, which is particularly relevant for moisture-sensitive battery materials.
Stainless Steel Flange Filters (FM-ST Series) — Built with internal and external mirror polishing to Ra0.3 and SGS-certified SUS304/316 materials, the FM-ST series operates at 1.0MPa with flow capacities ranging from 15 to 400Nm³/min across DN65 to DN300 flange connections. These filters offer C/T/A/F/H filtration grades, precision up to 0.01μm, residual oil as low as 0.001ppm, and a sterilization-grade P-SRF option verified through 100 percent DOP integrity testing — a hygienic, crevice-free design suited to clean compressed air systems where contamination control is non-negotiable.
Customized Filtration Systems — For unique operating conditions, Yuanmei Filtration engineers tailored solutions, including custom housing materials such as Hastelloy C276 for strong reducing acids and titanium for wet chlorine exposure, filtration precision ranging from 0.01μm to 100μm, flow rates from 0.1 to 100 m³/min, and specialized sealing solutions such as metal gaskets rated for 600°C ultra-high temperature applications.
Yuanmei Filtration maintains a closed-loop quality management system spanning raw material inspection, precision processing, assembly, debugging, and factory testing, certified under ISO 9001. Raw materials undergo spectral composition analysis and stability testing, while every finished product passes 100 percent testing covering pressure resistance, tightness inspection, filtration efficiency verification, and durability simulation.
The company operates an in-house ACF compressed air testing laboratory equipped with instruments such as the OIL-Check400 oil content analyzer, the PC400 particle counter, and the FA510 dew point sensor, enabling residual oil measurement to 0.001mg/m³, particle detection to 0.1μm, and pressure dew point readings to -80°Ctd — all consistent with ISO8573-1:2010 Class 1 requirements. Finished products also undergo batch sampling for a 1,000-hour continuous operation aging test. Products are supported by compliance documentation aligned with ISO 9001, ISO 8573-1, SEMI, GMP, FDA, and CE requirements. Standard products carry a 12-month warranty, while custom and sterile filters are backed by an 18-month warranty.
Yuanmei Filtration's business coverage extends across Southeast Asia, South Asia, North America, Europe, the Middle East, and South America, with core client industries including semiconductor, pharmaceutical, food and beverage, petrochemical, and new energy manufacturing. The company provides 24/7 technical support, standard product dispatch within 3 to 7 working days from stock, and custom filter delivery within 15 to 25 working days covering R&D, production, and testing. Core filter elements can be replenished within 48 hours to minimize production downtime. For international partners, Yuanmei Filtration also offers exclusive distributor authorization, technical training, and marketing material support.
